Let us talk about retaining rock walls, now this picture has been taken from the internet, where I could not find what I wanted, however, this is how a hybrid rock wall can look like when built properly. And this is what we explain in this text. But in the text, the wall is a different shape. 

Welcome to part two, DIY Retaining walls.  

Deciding to build your own rock wall.  

Anyhow, you needed more space, because you wanted to build a car port, and put a trampoline for the kids. So, you have been digging in the backyard, and finally you are satisfied that they can fit them in the space you have made. But now you have this bank that stands almost vertical in the backyard, it looks ugly, and you know that when the first heavy rain comes it is going to start washing it down, and worse still it may collapse. So, you think of building a retaining wall to hold the soil up. 

For this reason, you have had a couple of quotes and had a good talk to the contractors as you did not want to spend more money that was strictly necessary, they did their best but still you cannot afford to pay the full price, beside that you found that if you lay a dry stone wall, ether you have to use stones that have been cut at the quarry and they cost a lot, or you have to have a rock wall with a wider base and this is going to take away some of the space you created when you dug, so really you need to think about it.

So, you have decided to build the stone retaining wall yourself, what you have decided is that you are going to build an hybrid stone wall, which you believe can do the job without costing too much; therefore, you have looked for a rock supplier and ask for prices of the different materials you may need, because you think that you can afford it, if you do the job yourself.

By pure chance you have learned from the blokes that have given you the prices, how many cubic meters of rocks you need and other things that you were not sure before; well done sometimes in the building game things work out this way, you learn a bit from here a bit from there and then you can decide what to do with the information you have collected. There is nothing wrong for doing this, unless you do it purposely to learn something, but if it does not work out, then it is okay to use what you have learned from them.

I have to say that it has been done to me many times and that I have done this myself; not only on quoting but also in buying something new, if I have to buy something that I have never used before, I go to at least three places and inquiry about it, by asking the right questions not only I learn how much it is going to cost me, but I have learned how to use whatever I was going to buy in the first place, of course, I end up buying from one of them what I wanted to buy in the first place; sometimes I call this let me go first to spy and then to buy, I know that some of these people are going to feel a bit hurt, for using their time for nothing, but so what, sometimes you win and sometimes you lose, as I have said it has been done to me as well and I have felt a bit hurt, when I had to spend some time working out a price to build something, and at the end I did not get the job, so, I spent all that time for nothing, but that is life and we should accept the outcome whichever way it goes. Anyhow, now let us go back to building the rock wall.

-------------------------

Building the hybrid rock wall.   

This hybrid wall that we are going to build is a big job, it starts at the same level, as we have dug the ground approximately level, but because we are building the wall only to the height of the natural ground level, it is going to start from almost nothing and at the highest point will be 1.8 meter, it is really two walls that meet and forms a square at the highest point.

Here we must say that today some people think that this should not be done, as this is neither a rock wall nor a concrete masonry wall, as it mixes about everything, but so what, if it is convenient, why not do it? I must say that in my life time I have built walls like this with whatever was available on the site; and I mean everything in fact I was using stones that were laying in this small creek bed and pieces of concrete that we had broken to do some alterations and old bricks, some concrete and some mortar, this has happened a few year ago and last time I have seen the owner he said that the wall is still there. So, most things can be done if you know that it has got a good chance to last a long time.

Let us go back to build our hybrid rock wall. Now, to build this wall you need a few cubic meter of rocks, because you want the wall to look as a rock wall, you don’t need very big rocks or special size rocks, because you can use the cement wherever necessary to fill the gaps and this is good, since the cement is less costly, you need a mixer, you need some gravel, sand and cement; and of course, you must have the tools to do the job.

You got all this on site, and you can start to build. First of all, drive a couple of pegs in the ground, exactly where you want the face of the wall to be, tie and stretch a line on these pegs and see any adjustment that you need to do before you start laying the first stone. What you are looking for here is that the bank you are going to build the wall against has been dug straight, it is almost vertical or a few degrees sloping, you have dug a shallow foundation, because you want the wall to be strong and last for a long time, so, you are satisfied that the foundation is going to be solid enough, since it is well below the original natural ground, therefore, it can hold a lot of weight and pressure, because the ground is very compact. 

You have done all this, you have set the pegs again so that your wall is set to be at least 10” thick overall, you have chosen this thickness because most of the large rocks seem to be that thick, so now you are ready to lay the first course of stones, mix a few batches of concrete and lay it in the foundation and then before this concrete sets lay the first course of stones on this concrete making sure that the bottom of the stones are below ground level, so that the entire stone wall seems to start from below the ground; once you have done that you can fill the back of the stone with concrete a bit above ground level but below the full height of the stones, because you want to leave enough room to lay next course of stone easily. Now the wall is all set to go, but we need to reset how we must continue and complete the hybrid rock wall, the right way with the right lean against the bank. You need to lean the wall against the bank, so that the weight of your wall by itself adds strength to the wall.

-----------------------------------

Completing the hybrid rock wall. 

So, before we build this retaining wall, we must work out how much lean against the bank we want, here we must keep in mind, how tall and how thick is the wall, we don’t want the wall to lean too much and rely only on the dirt behind it to hold it back, but at the same time we want to lean it against the bank so that the weight of the wall is used to hold the dirt back.

Here we must go back to look at what happens if you lean a monolithic object to the point it is going to fall; what happens here is that the monolithic object is going to fall, only after its centre of gravity falls outside the area of the base. Now we don’t want to go this far, and we don’t want to use the centre of gravity to decide that, but we are going to lean the wall about two third of the thickness, so that the very top layer is still vertically one third of its thickness above the base; we believe that it is very safe to go this far and the wall would stand up even if we don’t backfill it. Anyhow, in our case we are not going to backfill it, because we have cut the bank exactly as the wall is going to be, you see we are going to use the bank as a template, so, we believe that we are not going to backfill it at all.

Now that we know how much we are going to lean the wall; we are setting a leaning profile on every corner leaning approximately 10 to 12 centimetres per metre and we are ready to resume building our hybrid rock wall. But there is still another important thing to work out; we need to make sure that when it rains the water that seeps behind the wall can run out, so, we must leave a way to drain this water out and at this level is the right place to do that, so, we choose a few spots about a meter apart and mark them, then when you lay next course of stones make sure that you leave a space between the stones that the water can run out, you must also leave the back free of abstractions for a course or two around this space, so, in this space after laying the front stone, just lay some smaller stones dry against the bank to stop the concrete blocking the drain, then you can resume to concrete the lot. Alternatively, you can lay a few short pieces of pipe across the wall for drainage, but you have still to make sure that they are clear of any obstruction at the back near the bank.  

So, now you can go back to mix some cement to lay your stones, you can mix a batch of river sand four to one that you can lay between the rocks to give them a bit of grip, you are laying the rocks in a straight line that you have tied on the profiles, when you do that make sure that this cement does not come too far forward, because you still want the rock wall to look like a rock wall, at the same time do not forget that you have to leave these spaces with no cement at all for the seepage where you have marked, after you have used the batch of river sand and cement and laid say a course of rocks, you can mix one or two batch of concrete to fill the back of the stones, then you repeat this procedure until you build the entire wall.

At the top of the wall, because the wall in not going to be level, you may have to do some adjustment to follow the height of the ground, here you have to use common sense the best way you can, if you happen to have enough wide and long rocks that can be used for a coping, use them to finish your wall, if not, just use your common sense and use anything that is available, even if it is going to be a strip of concrete in the back of the wall, so that all the wall is tied up.

I hope I have explained well enough for you to follow my way of building this hybrid rock wall. Here I want to add that this is just one way out of several other ways that can be used. A lot depends how the bank has been cut and if it follows very closely the shape of the wall, so, you can use it as if it is formwork, but if there is going to be some back filling to be done, you may have to consider some temporary formwork that can be easily removed before you backfill. All these things can vary from job to job, and if you see that it is hard to build your hybrid rock wall, then you must consider other ways to build your retaining wall.    

---------------------------------------------    

Why we need these retaining walls?  

We need retaining walls, when the block of land is steep. So, it requires a lot of work to be done, if you want a small portion of your land flat, so that you can stand and enjoy whatever is there to enjoy and do whatever you want to do in the open air.  See the photo here under, they have built a Besser block retaining wall with an indent in it, mainly to give extra strength to the block wall and to put this concrete slab and use this indent with whatever they want to do next. Note that above this block wall there is another sleeper retaining wall, these sorts of things are very costly, and we must plan it out before we start, anyhow, under below we are going to write about a Besser block retaining wall, first just a normal strong retaining wall and after that we are going to build a leaning Besser block wall, similar to the hybrid rock wall. 

Most retaining walls are made of concrete blocks, Besser block retaining walls are usually made with hollow concrete blocks, they are 190 x 190 x 390 mm. They are laid with mortar 10 mm thick joint, steel reinforcement bars are placed in the hollow part of the block, then they are filled with concrete once the walls are dry enough.    

Building a Besser block retaining wall

Besser blocks retaining walls require a reinforced concrete foundation with steel starter bars placed exactly in the centre of the hollow part of the block, when you look at the wall from the front or back, and if possible, a bit close to the side where the pressure of the soil is going to be, but that can be asking too much from the concrete man and the steel fixers. So, a profile must be in place before you can even concrete the foundations, or fix the steel in the foundation, because all measurements need be known and easily measured while working on it.

This is a very demanding job and it is not a do it yourself job. So, the name that I have given this article DIY retaining wall would not apply in this case, you see I apologise because I was forced to use DIY just to overcome the problem of the title that happens when we start a new article and find that the name we have chosen has already been taken.

Anyhow, when you start laying the first Besser block in most cases, it is helpful if you can start the first course with an open block, this block looks like a square C, and you lay it with the open side facing away from the bank that it is going to hold back when everything is done, the corners are built with normal blocks and most of the walls are built with blocks that look like an H, so, it is easier to fill up with concrete, once the wall has been built. Now while the block layer is laying the blocks, he will have to lay horizontal steel bars between the courses of blocks as specified, if there is a plan and specifications, or use common sense, or copy from the specifications of a similar job he has done, the vertical steel bar will be inserted from the top before or while pouring concrete into the blocks.

Now the reason why we need to use an open C shaped block for the first course, it is because it is necessary that before we fill up the blocks we remove the mortar that has fallen down at the bottom of the blocks while we were laying them, you see, we want a solid base and we want the concrete to bind around the starter steel bars that we have laid in the foundation and this is the best way to make the retaining wall as strong as we can. Once that is done, we can fix a plank against the openings, and we are ready to pour the concrete in the wall. 

Here we must say that for this retaining wall we have not mentioned any drainage yet, so, what happen to the water that seeps behind the wall needs to be worked out, you see, sometimes when we build walls this strong, there could be a reason that we do not want any water past the wall, it can be part of a base of a house being built, so, we have not even left any weep holes in the wall, because there is going to be a drainage pipe laid behind the wall surrounded by gravel. The wall might also be treated with special paints to waterproof it.

This is one type of blocks retaining wall, and I am going to write about another type, where we lean the retaining walls towards the bank for future back fill that it is going to hold up, this is a large job that we did years ago in a yard of a new large home in Redhill a Brisbane suburb. We are going to write it here, to show you another type of retaining wall and the many ways that can be built.

 

Redhill backyard problem solved. 

Years ago, we worked on this part brick house in Redhill, we say part brick house because the top floor of the house and the interior was made of timber, so, it was a brick veneer, the base was solid bricks and blocks, it was a large house, on a large block of land had two street frontages. It was on a hill and the difference between the front and the back yard was a lot, but the two street frontages was good, because the house was being built on the higher part of the block of land, where it was nearly flat there and almost level with the road, so, there were no problem building the house; but the back yard was very steep, in some places could have been up to 45 degrees.

So, when we finished the brickwork on the house we were asked from the owner, if we could build some retaining walls, because the backyard was useless as it was. So, after discussing the financial part how he would pay us; we discussed how we could fix the back-yard building block retaining walls. So, it was agreed that we had to lay these block retaining walls leaning a few degrees towards the bank. We had to build concrete stairs on one side, so that the house could also be entered from the back street, so, working together with the owner we did the following.

Because you cannot build a very high wall on the road boundary, first a section of about 4 feet wide (1.2 m) was dug and a foundation was poured, with starter steel bars as needed and the main wall was set about a meter from the road where the first retaining wall was to be build, this was the main foundation for a start, some of the small foundations and other adjustment we had to work out as the work progressed.

The decision was that we had to build the wall leaning towards the bank for extra strength; you see, when building retaining walls the weight of the retaining wall with the weight of the foundation must be more than the weight that the backfill can move, if possible that you can build a very strong monolithic wall and foundation together this is the best solution, in this case it was not possible, because the job was too big, beside that you need to have a very wide and heavy foundation and a very strong bond between the foundation and the wall, since this bond between the foundation and the wall is the weakest point unless it is concrete and poured together, but we were using blocks to build the wall, therefore, it had this weakness at the bottom of the wall, therefore, by leaning the wall towards the bank, the weight of the wall becomes  the first point or resistance.

Now, how much we must lean the wall was left to us block layers, because for sure there will be problems, and there were several problems to overcome; the first problem is that if you have to return the corners it cannot be done, but we had corners on the boundaries of the joining block of land, so, we had to think how to overcome this drawback, for this it was decided that we would not build the corners as usual, we should treat them as separate, but we would place a corner steel rod every course, instead of every second course, as in the wall itself.

There was also the possibly that while we were building the wall, if we lean it too much it could fall on the inside, while we were building it, so, we had to strike a balance. Knowing that this first wall was going to be no more than 3 meters high, we worked out that if we lean the wall 5 centimetre per meter, the top of the wall was going to be about 15 centimetre back from the perpendicular, the blocks were 19 centimetre wide and it would be okay, as once the wall was built it could stay up on its own without falling inside, but while we were building we should be very careful not to apply any extra weight on the leaning wall, just for fear that this could happen we added a couple of block piers behind the wall, this would not only make the wall safe for us while we were building it, but it also would make the whole wall stronger. 

Anyhow, we built this block wall placed the reinforcing rods in place, we also built some concrete steps on one side of it, so, that if you happened to be on the back road you could walk to the house, the ready-mix truck came, and the wall was filled with concrete and that was the first stage finished. We had to wait for this wall to become strong before we could backfill it, and then we could build another retaining wall halfway the backyard to finish the job.

Dear readers, be warned that this type of work can only done from very experienced block layers, as it breaks all the rules in the building trade, but we did it and it worked. 

Anyhow, this article is becoming too long, so, see you in our next article, Mix your own cement.

Building retaining walls, one.

WELCOME TO FRANK MENCHISE BLOG OF GENZANO DI LUCANIA, YOU ARE INVITED TO BROWSE AS LONG AS YOU LIKE. 

Hereunder let me paste of few links of my other blogs. 

(http://menfranko.blogspot.com,) (http://menfrancore.blogspot.com/,) ( http://ifyoubelieveingod.blogspot.com/,) (http://manneedsgod.blogspot.com,) 

This blog can be found in full at this link, DIY Retaining walls

We can build many types of retaining walls, this above is a masonry stone retaining wall, these types of retaining walls last for a very long time, when they are built well, like the one above, but they cost a lot more than other types of retaining walls. So, let us talk about how we build them. 

Welcome to our article, DIY Retaining walls. 

Dear readers, let us talk about how we build retaining walls, and why we build them. You see, most people that own a standalone house, want to improve their property by doing a few things in the yard, where they can stay outside and have a garden, or have a barbecue with their family and friends. But there are times when it is not easy to stay outside, because the yard is not level and, in some places, it is hard even to stand up straight, so, something needs to be done to improve the situation. In this case retaining walls can help solve that problem. But how do we build retaining walls one may ask?

Before we answer that question, let us talk about the retaining stone wall shown here in this article, I reckon that it is a well-built stone wall, but a wall like that is very costly and hard to build, unless you are an expert and know what needs to be done.

But, let us see what we can learn from this stone wall picture, just by looking at it and trying to imagine how this wall has been built. What we can note from the picture is that the retaining wall has been built leaning towards the bank it is holding up, we can see this at the right end of the wall where the wall goes around the corner,  the stones are laid dry as there is no sign of any mortar around, the stones are not all the same size, and they are longer and shorter stones, but they are all the same thickness and they are laid the same way as we lay a course of bricks, but at the same time the mason has made sure that the vertical join are not setting one above the other, and this is a hard thing to do with stones all different size, everything is so tidy, the wall thickness is not shown anywhere, but because there is a very low wall started near, it seems that the wall has been built like a double brick wall, we can also guess that perhaps some of the short stones are not really short, but they have been laid like a header brick to tie the front with the back of the wall, at the top the last course of stone, the stones are longer and as wide as the whole wall itself, so that they would tie everything together. These are the main features that we can learn from looking at this stonewall picture.

Now that we have explained that, let us write how to do it yourself retaining walls. You know, there are many types of retaining walls, some are easy to build others are hard to build, and there are many reasons for building them. So, this article is going to be a long article, because we want to tell you about them, as much as we can. Anyhow, because this is a long article, I need to tell you, that we have split this article and we are writing two blogs, this is part one.   

---------------------------------- 

How to build retaining walls.

Okay, there are several ways how to build a retaining wall, and there are several types of retaining walls that we can build. Therefore, first we must see what we gain by building this type of retaining wall, or that type of retaining wall, and above all how much it could cost, before we can decide what type of retaining wall to build. Now we want to build our retaining walls with building materials that are easily available, to avoid extra cost. So, look what local materials are available, where you are. You see, if you are in a place where stones or rocks are plentiful, and you may even have some of them in your yard, then it is cheaper to build your retaining wall with these materials, and even if you have to buy the lot they are cheap anyhow; but if you are in a place where there are plenty of trees and there is even a sawmill nearby, then it is more appropriate to build it with timber.    

Having said that, it is obvious that for you to decide, what is the best retaining wall to build; we need to explain to you what could be done and how can it be done. Therefore, hereunder we will try to do that. Let us start with a very easy and cheap retaining wall that most people can do themselves, even if they don’t know much about building, as long as they have a few tools and know how to use them; here we are saying that anyone of us can dig a few holes in the ground to place a few short posts and place a couple of sleeper timber planks against those posts, then secure them by nailing or screwing them to the posts. It sounds and is simple, isn’t it? But this is not the only retaining wall that we want to show you, so, keep reading this article, while we add more descriptions, because you can even learn how to build them.  

Timber sleeper retaining walls. 

Building a low timber sleeper retaining wall is easy, just about everybody can do it, you can do it yourself, if you follow our explanation in this text here, all you need is a crowbar, a post hole shovel, a hammer a few long nails or screws, a saw, a type measure and a few treated pine sleepers that today are easily available at most timber yards.

If you are in Brisbane Australia, these are a couple of addresses of local timber merchants and hardware to get what you want. If you are somewhere else, you need to find your own.  ‎

 http://en.wikipedia.org/wiki/Bunnings_Warehouse

Now, let us assume that you have visited your local supply, and you have got all you need, so, you are ready to start, you have also worked out where you want your sleeper wall to go; So, start digging the first hole where the wall starts, you need to dig this hole about 600 mm or more in the natural ground for the post to be strong enough to hold the pressure of the retaining wall when the wall is back filled; you may have to concrete around the post for extra strength, but this is not a must do, if the retaining wall is low, because you can replace this with, packing the soil tightly around the posts and if you have some rocks, wedge them between the top of the hole you have dug and the post at ground level, because the rocks will exercise their pressure on a larger surface of the natural soil than the post, they will be able to hold back the soil pressure of the wall more easily, now that you have done the first post, you can repeat the same procedure for next post and so on.

The posts can be made from the same material of the sleepers; you can saw them to the right length and fix them in the ground as we have said above. Now, to make it easy let us say that your wall is going to be the length of a sleeper plank, and you have dug the two holes and fixed the two posts. So, now you can just place the first sleeper against the posts at the required level; the levels of the sleepers is better if you work it out from the top down, because it is easier to change the bottom than the top, you see, in this case you can always dig a bit or add a bit of soil at the bottom to fit the bottom sleeper. So, mark on the posts the level you want to reach with your last sleeper, and then mark down from this level the number of sleepers you are fixing on these posts, once you have done that you are ready to fix your sleepers on the posts. 

We believe that most people can build a timber retaining wall, perhaps not as high as this one shown in the picture, but say a couple of timber sleepers high. Anyhow, let us explain how it is done.  

Fixing your sleeper to the post. 

To fix the sleepers to the post now is simple, but still you need to do a few things right, if you want your wall to last a long time, with the materials you are using now; it is useful to know that in this case it is highly advisable that you use galvanized nails or screws to fix the planks to the posts, because the retaining wall is in contact with the wet or humid ground constantly, therefore, normal nails or screws will rust easily.

You have bought some 75 mm and 100 mm galvanized nails to do the job, so, you hope that you can drive these nails into the sleepers and posts just by using a hammer, because it is the fastest way to get the job done. 

Okay, if you are good with your hammer and can drive nail easily it is the best way to go, provided that the timber is soft enough to do that, and if you have used treated pine sleeper it can be done, as all you need to do now is to place the sleepers where you have marked on the posts and nail them in, and then you can backfill behind the retaining wall and the job is done.

But what about if you are using hardwood or old dry hardwood, because you got it very cheap from a second hand timber yard, because they were overstocked they sold this timber at a very special price, which was less than half the price of the treated pine sleepers; so, you were happy to buy it because it was cheap and the timber being hardwood lasts for a very long time, but now you may have a problem to fix the sleepers to the posts, because it is near impossible to drive nails into this old dry hardwood timber, unless you drill a hole for every single nail, and even then the nails can bend even if you are an expert with the hammer.

If this is the situation and it is hard to nail this timber together, you can overcome the problem by using couch screws or bolts, so, you use a drill and drill a hole for your galvanized couch screws or bolts and tighten the screws or the bolt nuts with a spanner. But if you don’t want to do this extra work and you want to use the galvanized nails that you have already bought, then you can do the following: drill a hole as deep as you can just use a bit a fraction smaller than the diameter of your nails, then try first with the 75 mm nails how you go, if it works and you believe that the nail go deep enough into the supporting post and hold well then your problem is solved, but if the nail bends or don’t go deep enough then you can try the following, and this is one of the last tricks of the old trade, which not many people know or use, this trick is not a trick at all and once you know it, you can feel even stupid for not thinking about it yourself; so what is it? Okay, when you pick up your nail to nail in the hole you have drilled, dip the point of the nail a couple of centimetres into a bit of Vaseline or mechanical grease, if this is not available just wet a bar of soap and rub the point of the nail on the wet soap, this greasing of the end of the nail will make it easier to drive it into any wood including dry old hardwood.

I believe that I have said enough about simple timber retaining walls, for you to have some idea how to build them, so, now let us talk about another type of retaining wall that can be easy to build, it is a type of concrete wall that the blocks are laid dry, so, anyone can have a go; and if you don't get it right the first time it is easy to fix.

Link Block Mortar-less Walls. 

Link Block Mortar-less Retaining Wall Blocks

This is a different type of retaining walls made with dry blocks, the mortar is not required, it is a low wall easy to build, so, most people can do it themselves. Now let me tell you this, on the internet I have found this local supplier who has placed a few short videos how to build these walls; the videos are at the bottom of the page, please use the link here-under, I reckon it is worth to watch them, if you want to build any retaining walls. As I have said this is only a local supplier in Brisbane Australia, therefore, the same materials may not be available where you are living, but by watching these videos you are going to learn something useful anyhow. 

No need for Mortar

So, I hope you have used the link above and you have been able to see the videos. Anyhow, whatever you have learned can be helpful one day.

And now I want to explain a certain situation that I have come across while I was writing this article.

 

Now, as I have said, not all concrete retaining walls require fresh cement when you build them, some of these concrete blocks are made to be laid dry, like the one in this photo and many other sort. 

Let me explain the situation. 

Dear readers this article was supposed to be about retaining walls, but as it happens I was forced to change that name because it was already taken in Hub Pages, so do not aspect that all the retaining walls described here are suitable to do it yourself, because we have named our article, DIY Retaining walls, because the retaining walls that we are going to describe here are not easy to build, so, they are jobs for trades people, but if you feel that you can do it then have a go, sometimes a bit of challenge is good for you. Now that we have explained the situation let me continue to describe how to build a garden rock retaining wall.

------------------------------------------- 

We must say that rock retaining walls blend well in the garden, they are natural since rocks are found everywhere in the natural state among trees and grass. 

 Building a garden rock retaining wall. 

To build a garden rock wall as shown in the picture is a lot harder than you think, and you need to know how to go about it, you see, you need to have a good eye to see how the rocks that you have can fit together to make a wall. There are a few ways how to do this depending how tall the wall is going to be and lots of other things.

You see, if you have only a very low wall you can just lay one single rock one after another, or two rocks one on top of another making sure that you choose the best face to show at the top and at the front, the other part of the rock can be hidden in the ground, or at the back since you are backfilling behind the wall; in this case it is not necessary to use any concrete, as the stones can be laid dry, but if you want you can use concrete.

Before you start the wall, you must dig all the grass and loose soil, even if your wall is going to be low. If the wall is going to be in a place where the ground is slopping down, make sure that you dig at least a few inches into the solid natural ground, so that the wall you are building can sit on firm natural ground, so, your wall is not going to slope down the first heavy rain you have after building.

Now, in this example, we are building a low stone wall and we are not going to use anything to bind the wall together, so, there is no cement or anything else between the stones, in this case because there is nothing to stop the rainwater to run between the stones you don’t need to worry about drainage. You see, one of the greatest problems with retaining walls is the water that can build behind them, the water and wet soil puts pressure on the wall and if the water cannot get out the wall is going to fail.

Now it is helpful to have a look at some stone retaining wall, and for this reason in mind I have found this link in the Internet; so, have a look at the pictures in this link; www.australianrockwalls.com.au/  there are several types of stone walls, now you can start thinking how and why they have been built that way. 

Anyhow, this is the first part of this article, see you in next part, buiding rock retaining walls.

In Brisbane there are many stand alone houses, this type of house above we were building in the eighties, they were more expansive that the houses that we were building in the sixties, but they were better houses than the smaller timber house of the sixties. 

The houses that we were building in the seventies, were mostly timber houses on concrete stumps, then they started enclosing part of the house below, with brick walls or timber partitions, later they were built with mixed up building material.   

Welcome to my article, House building in Brisbane. 

House building explained. 

Dear readers, today we build many different houses, depending on the country or even the zone where we are living. 

Anyhow, we must build houses to live in them, so, in this article we are talking about that, because this is what I did when I came to Brisbane Australia in the sixties. I know that today building houses can be different from then, but not very much. Anyhow, we are going to talk about house brick bases, and working as a brickies labor.

House building in Brisbane in the sixties, was and is different from the old continent of Europe, because over there most houses are made of masonry, timber over there is more expensive than in Australia, and because of the colder climate. You see, thick walls of masonry absorb the heat during summer and act as storage of this heat by releasing it slowly during the colder months.  Anyhow, houses over there are built mostly from masons’ bricklayer and concreters, and the carpenters play a smaller part than they do in Australia.

Therefore, when we the European migrants came to Australia in the sixties, we thought this is strange to live in timber houses, and we were surprised to see that the carpenter played the role of builders, when houses were being built, because in the sixties most houses were made of timber, we are saying this to compare houses building, between the old continent and Australia in those times. Now we are not saying that this was good or bad practice, since we soon accepted the way of life we found, and we thought there must be a good reason for it.

So, we all did what we had to do in whatever employment we found, and those of us who ended up working in the building industry, we did what we were told to do. But as we know, everything changes with time. As we will see later, when building houses with timber will change even here. Now that we have made this comparison, let us go back to what I was doing myself in helping to build these houses. Therefore, let us talk about how most houses were being built by teams of workers, because that is how we were building houses in Southeast Queensland in the sixties.

------------------------------------------

House building in Brisbane in the sixties.  

In the sixties and seventies, most houses building were done from teams of subcontractors, who had their own team of building workers, even if they were only a small team of two or three people, like the team I was working with, which had two tradesman and one labor (myself).  Now let me tell you, what sort of teams were there; first there were the concreters and bricklayers. When building small houses that did not have a lot to do with these trades, concrete and brickwork could be done from the same team; then there was the carpenter team, then the roof, the electrician and the plumber and the plasters. The work of the builder, which most times was the leading carpenter, because he had the largest job; not only he was building the timber frame of the house, but had to organize all the teams in a way that was appropriate, so that they were not in each other way while they were working, and finally do all the finishing work required.

In those times to be a builder of these standalone houses on an approved block of land was easy, as long as you were a building tradesman and had building knowledge and had the money to build them, you had this opportunity to build one of these houses, of course there were local authority inspections to be had while we were building, but if you knew what you were doing it was easy to pass. So, there were many house builders around that would hire teams of building workers as we were.

I need to say that the building industry in Australia is one of the main driving forces of the economy, since it employs lots of people that are willing to do hard physical work to earn their living, you see you don’t need to be a learned person to work on the building, all you need is common knowledge of things and enough English to understand what is wanted from you, if you know what you are doing; or you work with people that speak your native language and they explain to you what you need to do, but you had to work hard to keep this job.

I believe that in the sixties and seventies there were good opportunities to work on building houses, because the price of the houses was more affordable than they are today. Just looking back at those prices, we can say that one of those cheaper houses would be worth about four time the average wage of a person working full time for a year, so, most people could afford them; therefore, those builders that were building them were able to sell their houses at a decent profit that would enable them to build other houses.

As we know things changes with the passing of time. So, let us look at what has taken place, in the houses market. As we have said, in the beginning houses in Brisbane were mostly made of timber, and they were set on timber stumps, then in the sixties because the timber stumps would rot or they would be attacked by white ants they gave way to concrete stumps, and some brick walls under the house. Then from just a brick wall in front of the house they changed to a full brick base and concrete stumps or steel posts, then came the era of the brick veneer and finally concrete and cavity bricks. Today, I must point out that building apartments is different from the sixties, they are mostly made of reinforced concrete. 

Now that we have said a few things about the history of house building in Brisbane, let us talk about my contribution in the building industry and what I did during the earlier part of working building houses. If I remember right in my last article, I was talking about how we were concreting the stumps for a new house, and we had laid the foundations for brickwork, therefore, let us talk about the brickwork that we had to do, to build a brick base under the house.

-------------------------------------

 Brick base under timber houses. 

As we have said, there were many types of houses being built in the sixties, some of them had a brick base, or the front wall under the house built in bricks. So, this was another job that we did with our small team of bricklayer and concrete workers.

In order to be efficient and competitive a small team that lays bricks needs to be made of two bricklayers and a labor, of course larger teams can work well with a different number of people, anyhow this is what was like then and our team had two bricklayer and a labor as myself.

Now that I have explained that, let us start working, so that I can describe how things work out, who does what, and how it should be done. It is the bricklayers’ foreman that decides from where to start. But if he is not there, then it is up to whoever is there to start getting ready where the bricklayers must start. This is not hard to know because to lay bricks you must start from the lowest part of the foundation, So, when I was working as a bricklayer labor, I would get ready the bricks and the combo-boards, at the lowest point of the foundation, so, when the bricklayers had to start, all I had to do, was to give them fresh mixed mortar on these combo-boards, and then continue to supply them with brick and mortar as required.

Here I should say, that it is hard work for the bricklayer-labor and for the bricklayers, because at the end of the day one has to handle so many bricks, since in a day a bricklayer on a normal wall is supposed to lay on average 400 to 500 face bricks, or up to a thousand common bricks, of course this is wishful thinking and most times we didn’t, but we had to try to get there; this is how the bricklayers’ team works. Now let me break it down and describe what the labor does, and then what the bricklayers have to do; I know all this because later I became and worked as a bricklayer for decades myself, but now let us talk about what the bricklayers’ labor does.

-------------------------------------

 Working as a bricklayer labor. 

What you do, when you are working as a brickies labor.

The brickies labor job is hard work, it is also a semiskilled work, since he has got to know how to make mortar and to supply mortar and bricks to the bricklayer at the right time in the right place. It is obvious that he must have at his disposition a mixer to mix mortar and wheelbarrows, other small devises to help him achieve that.

Here I need to point out that to start a new job it is very hard, as the ground on the site is not flat and there are hips of dirt around the foundations where the brick or block walls are going to be built, so, the labor needs first to flatten the ground a bit, so that the mortar boards and the bricks can be positioned at the right distance from the foundation, this is about 60 centimeter plus from the walls that are being built, so that the bricklayers have enough room to move and at the same time they can reach the bricks and the mortar-boards without walking; in order to achieve that there needs to be one mortar boards and then one stack of bricks, and again one mortar board and another stack of brick, and so on for the whole length of the wall being built. Now that we have made it ready, the bricklayers are going to start to lay bricks, let me prepare the mortar, which some people may call cement or combo.

Preparing or mixing the mortar

There are rules to follow how to mix good mortar, so, one must keep in mind first what sort of material is available and can be delivered on the local site, because quantity and quality may vary with the locality. Anyhow, let us assume that for this job a load of brickies loam has been delivered on the site; in this case this brickies loam has some lumps in it, so, it needs to be screened before or after mixing the mortar, as I have screened it, I am ready to mix it now.

So, I start the mixer and put in clean water, and a small measure of mortar mix (this is a chemical that helps the mortar to be more workable) then I put in say a shovel full of Portland cement and four shovels full of brickies loam, this is how we usually mix mortar to lay bricks, it is one part of cement to four parts of loam by volume, therefore, for bigger batches you can have say; three shovels full of cement and twelve shovelful of loam and so on. Of course, these quantities can vary, if for instance it is written in the specifications that the mortar must be made with different amounts of materials.

Anyhow, let me go back to this batch of mortar that I have mixed to the right consistency; Now, I take the wheelbarrow near the mixer and tip the mortar in the wheelbarrow, and then take the wheelbarrow with the mortar near the mortar boards, here I wet the mortarboards before I place the mortar on them and finally I am ready for the bricklayers to get started. From now on I must make sure that the bricklayers have always enough mortar and bricks, otherwise they will we shouting at me Bricks! Or combo! (Or mortar!). 

Dear readers, if I have missed a few things you have to use your own common sense to get everything going the right way, you see, most things on the building site is plain common sense.

I believe that I have said enough in this article, although there is a lot more to be said, how the bricklayers are going to lay bricks for this brick base. But I am going to leave it for next article, which we are going to call, DIY brickwork, there I will try to explain it in as many details as I can, how to build a house brick base. In fact, we are going to write a group of articles about bricklaying and other building trades; I hope that I can line them up in such a way that they make sense and it is easy to follow. Anyhow, see you soon in our next article, DIY brickwork.

Australia affordable houses,

WELCOME TO FRANK MENCHISE BLOG OF GENZANO DI LUCANIA, YOU ARE INVITED TO BROWSE AS LONG AS YOU LIKE. 

(This blog cannot be used to link to Google Ad Sense) But I can link it to other blogs or sites, http://menfranko.blogspot.com,http://menfranco-re.blogspot.com/

Because a simple small house like this one, would be more affordable than a large one, it will attract more buyers than a large and well decorated house, that is why even today there are builders that will build small houses instead of large houses.  

Welcome to my article, Australia affordable houses, 

Dear readers, as I have said in our last blog, I was working building these affordable houses. In those times, new affordable houses were built on the fringe of the city in new suburbs, which is the same as today, if you want a new affordable house, you must look for it, in the new suburbs.   We were also talking about earning and saving money, one of the aims for saving money is to buy our own house. So, let us talk the houses that we can afford.

As we know, houses are not all the same. Of course, we want to live in the best houses available, but most of us cannot afford expensive houses, therefore, we should be happy to live in any house that we can afford to buy or rent.

For this reason of affordability, to satisfy the house supply market, there are several types of house that are being built at any given time. In this article, we are going to talk about the type of houses that I ended up working on, in the early sixties. Because this article is meant to cover the story of my life, and what I did for a living.

In the early sixties, I ended up working on average houses that the working class could afford to buy, or at least the aim of the builders that were building them, was based in this affordability, since they had designed them with this purpose, because in the end, even though they had been built cheap not all of us workers would afford to buy these types of houses. But anyhow this was the purpose of building these types of affordable houses in the early sixties.

Now let us try to describe how we were building these houses from scratch.

---------------------------------------------------

Building houses from scratch

Anyhow, I am writing these articles about building houses from scratch, because I want to tell you the story of my life, and what I did when I came to Australia. But at the same time, I want to write something useful for my readers, and I believe that knowing how houses are built is useful to know, since knowing a few things about building houses comes handy at times; you see, we live in houses, therefore, we want to know as much as we can about them. Because we need to know how to do it yourself repairs and other things, since houses need to be maintained, if we want to enjoy them fully. So, I am going to describe how these houses were built, with as many details as I can, so that anyone interested can learn something useful from these building articles.

Now has I have explained in our last article, I was working in the building industry with this Italian builder, which was good for me because my native language is Italian. Now, with this builder not only we were re-stumping or building rooms under the existing houses, which required a lot of work to be done by hand, but we were building new houses from scratch. As I have said at the beginning of the sixties most of the digging were done by hand, specially the type of work that we were doing on these new houses, as machines were expensive to hire then, So, they were used only, if there was a lot of digging to be done, and with the machines of those days we could only dig straight forward things and not small detailed digging, as they were required to build these houses, anyhow as I said, I did a lot of this digging work myself, as I was employed as builder labor, and this was one of the jobs that I had to do.

Therefore now, let us imagine that I have finished digging the foundation and these stump holes for this new house, and now, we need to lay concrete in the foundation, and to concrete the stumps foundation and the stumps themselves. So, let us go over what we had to do, because in those times these things were all done by hand and started from scratch.

------------------------------------

 Making your own concrete.  

Making your own concrete on site from scratch. Anyhow today you might think that this is an old way of mixing concrete, and it may not be used much. But if you happen to be in the middle of  nowhere, this is what you need to know to make concrete. 

So, let me explain, what is meant by concrete in buildings and how it is made You see, if during your life, you are going to do renovations, it is useful to know how to make your own concrete, so that you understand what is required and how and why it must be done in certain ways, you will find this information written in this article. Some people can say that today things are different, so why bother to tell us this stuff about how to mix concrete properly, when we can buy concrete ready mixed by truckload, or in bags and all you need to do is to add water to make concrete. I say, okay, you can do that. But there are times and places, when you must do these things the old way.

Therefore, I believe that you still need to know how concrete is made from scratch, because that is the only way if you don’t want to make mistakes. Therefore, let me tell you how we were mixing our concrete in the sixties, and what is required to do that and how it is supposed to be done, if you want a good job done and the concrete to last a long time.

By the way, here we need to clarify one thing, what is meant by the word concrete, because most people replace it with the word cement. On building sites, the word concrete means the element mixed together able to harden to a solid consistency within a certain length of time, therefore, it has got to be done the right way.

One of the most important things while mixing concrete is that the concrete must be well mixed and to a workable consistency using the least amount of water possible, because if too much water is used then the concrete becomes weaker, therefore, it must be done properly.

Usually concreting and other jobs are done according to its specifications, you see, any firm that makes building plans, for a house or something of more importance, they must write also the specification how the job needs to be done. In these specifications it will be written what material to use, how to use it and the quantity and quality required. Therefore, to concrete a foundation for an average small house, the specification could state that the concrete must be mixed to a consistency at least 1 to 6; for people that knew this it meant that to mix the concrete you should use 1 part of Portland cement 2 parts of river sand and 4 parts of gravel (aggregate) and mix it as required until an even consistency is achieved. For the stumps usually would be a bit more cement than the foundations. But I must say that sometimes even these rules had to be changed a bit depending on the material that can be delivered on that local site.

Now let us say that we are ready to start mixing the first batch of concrete, as we have made everything ready, and everything has been delivered. To make concrete you need at least four elements of materials plus clean water; 1 Portland cement, 2 washed river sand, 3 clean or washed gravel and 4 reinforcement steel rods, and it is helpful if you have a mixer if you have to mix a large amount of concrete, because to mix by hand is hard work and the concrete needs to be well mixed.

Now let us start the mixer and make the first batch, while the mixer is turning around, the very first thing you put in the mixer is water, one must be careful not to put too much water to start with, it has got to be just enough to mix everything to a certain consistency, so let us say that we put 8 litres of water (the amount of water can be different, since it depends on the amount of water that is already in the (sand gravel) aggregate) then we put in the mixer cement, next is the river sand twice as much as the cement and then the clean gravel 4 time as much as the cement; here the mixer is going around and mixing everything together.

Please note, that if you change the way you put your materials in the mixer, from what I have described above, you may have different result, and usually it would take longer to mix everything properly and to the right consistency.

For people that do this job all the time it is easy for them to see if the concrete that is being mixed has the right consistency required, once you know this, if it is too dry just add a bit of water and if it is too wet you should add a bit of everything else. There you are it is not too hard if you know how to do it.

What I have written above applies only to house building of less importance, for building that are large and important the concrete needs to be to a very high standard and specifications, so, here again you need to know what is needed before you do anything, and if necessary consult the expert. 

---------------------------------------

Concrete requires teamwork. 

To concrete well and do a fair amount of work on these houses you need a team, even if it is a small team. Our team was usually three of us, I as builder labor, John as bricklayer and Con the contractor who was a bricklayer and concreted. We didn’t mind if we switched around a bit to do the job. So, I was usually on the mixer mixing the concrete, one was with a wheelbarrow taking the concrete from the mixer to the foundations that we were concreting, and one was fixing the concrete in place.

Fixing the concrete for the foundation was physically the lightest job, when we were mixing the concrete with this mixer on site, but it is the most responsible job, because while concreting the foundations, you must make sure that the steel rods reinforcement was in the right position, at the same time you had to pack the concrete down and then the concrete in the foundations has to be finished level, this was easy when the ground was level, but when the ground was not level, it was necessary that steps were made and they had to be to gauge, which was equal to the thickness of one or two laid bricks or more, or the thickness of a laid block, if blocks were going to be used to build the walls on this foundation, whatever was going to be used to lay on the foundations, we had to try to make an adjustment while we were laying the foundations; therefore, this was the job for the experts, at that time it was not that hard, because mixing by hand even using a mixer was a slow job, so, the bloke that was fixing the concrete had enough time to do his job right.

What I have written above is how we used to lay small house foundations in the early sixties, which are the same as we lay foundations today, except that today we order concrete already mixed, but we have to be ready with everything and everything has got to be in the right place, because the concrete ready-mix truck will unload its concrete quickly, so, there is no time to do anything else, except to fix the concrete at the right level as quickly as possible.

----------------------------------

Concreting stumps on site

Now let me go back again to the early sixties, when we were concreting these stumps on site, this procedure is not done much today, the reasons for this change it is because the buildings have changed, and today these stumps can be made in a concrete factory, and when cured can be delivered to the building site, where the worker can erect them as required.

To concrete these stumps on site we had steel forms of various length, and these forms were assembled together with steel pins, so, we would assemble these steel forms and then start to mix concrete, we had also make sure that the stumps foundations were exactly in the right place by using the marked profiles and tight line between them.

In this case, it was an easy job for the fellow that is mixing concrete, but a lot harder for the blokes that had to pour the concrete in the stumps form-work and make sure that the stump was exactly in the right place and finished at the right height and were also plumb (perfect vertical position). It was also necessary that some reinforcing rods were placed in the right position with a purpose made devise. These are how we made those onsite stumps in the sixties.

These concrete stumps that we made in the sixties were better that the timber stumps that they were replacing, because it was an improvement as they did not rot with the passing of time and the white ants could not eat them. Here we can say that these concrete stumps on site were easy to make, if you knew the procedure, in fact it was easier to make a set of stumps than to fix concrete stumps made in the factory, as there is no heavy lifting involved.

I believe that we have said enough in this article, as we have explained the work that we did on these affordable houses and we will be coming back to talk about more building work in our next article, house building in Brisbane. See you soon.

Money and working with this Italian builder.

The workers cottage, this house can be said that is a much smaller version on the Queenslander house

Learning how to earn and save money

Now let us go back to talk about money, as we were sating in our last post . Whatever you do in life, the most important thing is; Earning and saving money. In my case, because there was uncertainty of not having a permanent job in the building industry, we soon learned that whatever money we earned from our job, we had to save some, otherwise we could have problems soon or later; so, this disadvantage that we had in this job pushed most of us building workers to become good at saving money, because we wanted to feel safe and independent.

So, let me talk about money. In Australia because the economy is based on capitalism the more money you can earn and save the better off you are; of course, this is also true to most other part of the world, but in Australia seems to be more so, because it is a new country, and people rely more on what they can earn than anywhere else in the world. This is because there are not existing reach families that live on the earnings of the properties that have been passed down from generation to generations. Therefore, in Australia is mostly up to yourself, if you want to get richer, you should try harder to earn and save money. You see, most of the people here, have earned their own money.

Therefore, we must understand that in Australia, not only you have to try to earn money, but it is important that you should save it too, and at the same time you have to try to improve your working position, so, you can be more independent and not rely on others. This attitude can help if it happens that you lose your temporary job, and also by saving money you can start one day buying your own house, which is the most important thing that people must do, if they want to live an independent decent life. I know now that most of you are saying that this buying a house is a hard thing to do, but you see, this can be done because I have done it myself.

Anyhow, I believe that I have said enough about this money business; so, let me go back to tell you, my progress in the building industry and what I did to become a tradesman.

-----------------------------------

Working for this builder

Working and learning with this small Italian builder

Dear readers, in these articles, while I am telling you the story about myself working in the Australian building industry, I am going to try to give you details of how things were done in those days; therefore, if you are one of those people that want to do your own building renovations one day, on those building that we built then, you can somehow guess what you can find, because you already know how we built them.

Now let me go back to when I started work with this Italian builder, who did bricklaying and concreting, we were working on houses and because there was not enough bricklaying work on these houses, as they were mostly built with timber, we were building only the foundations, the concrete stumps and some brickwork as the base of the house. Of course, we did also some jobs under the existing houses and this has given me an opportunity to learn many things about those old houses in Brisbane.

Just for comparison sake, to see the difference between those times and today, let me describe to you what we did to prepare a new base for a new timber house, which would be setting on concrete stumps and some brick walls.

First of all, we went to set up the site, if it was not set up from the builder or carpenter that was building the timber house. This setting up required that we should fix some timber frame to the ground with pegs and per the measurement in the plan. These timber frames are called profiles, and they are marked accurately to the measurement on the plan, so that we had the right measurement to go by, to start digging the foundations for the stumps and brick walls.

Then we had to dig the foundations and this was mostly my job as I was the labour and I was pretty good at digging, this may seem hard to believe but even digging one has to be an expert to do a good job, as the shape and depth of the foundations is important to do a good job. Just to show you what I mean to dig a hole for a new concrete stump, 20x20 centimetres as most stumps were supposed to be; the hole for this stump should be in exactly the right place, it should be at least sixty centimetres deep in natural ground and at the bottom should have a circumference of at least 40 centimetres or more. These were the average specifications then, unless it was stated otherwise. I know this because I have dug several hundreds of them if not thousands.

All the tools that I needed to do this digging job were a pick a post hole shovel and a crowbar, it usually would take me a couple of days to dig the entire house holes, which could usually be between twenty and thirty holes. You see I was able to dig a hole in less than half an hour, but it was hard work. Sometimes when there was some brickwork to do, we had also to dig these foundations by hand; the foundations were usually dug according to specification, which usually would be 60 centimetre deep in the natural ground, this means that if the grounds had been filled up that filling should not be counted as depth.

Anyhow, before I finish writing this article, I want to say that those houses that we were building in the sixties, with this builder contractor that I was working for, they were average affordable house that the average family could afford to buy, and therefore, they were sold easily.

Now, I believe that I have said enough in this article and although there is a lot more that can be said, we are going to tell you in our next article, which is going to be about how we made those concrete stumps on site, while we were working on these,   Australia affordable houses              .

See you soon.
