Bricklaying 101 : How to build a brick wall
Here in front of me is all the tools that are required for brick laying. You can see I’ve goy my trowel, my hammer, my levels. I’ve got a shovel, I’ve got my trustworthy wheelbarrow, Lime ??(SP), cement and sand.
So what we have to do first is set up our profiles. We’ve got our measurement on the wall.
A builder supplied me with that measurement there, was 1650 back up the wall. Now I’m using today just a bit of 9035 pine and generally for brick laying we use 45 x 45 steel but these are fine.
Make sure they’re straight and if they’re straight then they’re right to use because that’s what our brickwork’s going to run off. So what we need to do is we stand that up, we need to have a packer sit behind the profile so that we can get our string lining behind. And make sure that our line is visible further back here and then we’re just going to clamp this to the wall.
So I can see my line there, so now all I have to do is plum down. Now, it’s very important to make sure that the bubble is sitting dead centre of the two lines. So that’s bang in the middle so I’m happy with that.
Okay, now what we’re going to do is we’re going to mark the gauge on this profile which is not really that important because we’ve got existing brickwork, but for the sake of the exercise I’ll show you what to do. So, set the level to get the level up the brickwork just simply mark underneath the level. Then we’re going to take our gauge rod, which I’ve already marked off the existing brickwork, now what we’re going to do is we’re just going to hold that on the top level mark there and then we’re going to transfer the rest of these – so it’s the height of the brickwork.
So we’ve got our profiles set up. We’ll duck our line in behind the profile. And what we do for starters is we have to set up a level line. So what I’m going to do is I’m going to set this with five course above – one, two, three, four, five. Now I’m going to go over to the other wall here which is also completed and I’ll need to count down five from the top – so, one, two, three, four, five.
So the line needs to be nice and taut. If there is a sag in the line then your brickwork is not going to be level. I’ve got my line set up. So what I need to do to check that this concrete’s level or close enough to level, is I’ll put my gauge right here and I can see on my gauge rod that I need to get up probably 20, 25 mm, which is not a bit deal. I’ll be able to do that easily enough.
So what I’m going to do is I’m going to lay this first brick wih a larger bed than I’d normally lay. I’m just going to pop him down there. I’m just using my eye for now for sight, but then I’ll sit my gauge right on top and that tells me that I’ve probably got half of it there, which I’m pretty happy with. So I’m just going to get half to start with and then probably get the second half in the next course.
So what I need to do now is just grab my level and I’ve just go to plum down to make sure that’s in the right spot. That’s essentially where I want to have it. So what I’m going to do now is I’m just going to block this one down. Just put a bit of mud on the back of the brick. Just creates an angle so that the brock will sit forward and it will hold the line down for me.
And you’ve got to be very gently when you do this, because you can actually knock the brick and then you’ll lose where you’re at.
Now I’m right to lay this first course. This bed is a lot bigger than it would normally be, so I’m going to need a little bit of extra mud on the bottom. So you take up this much mud for buttering a brick and then just flock it back onto the trowel ’til it settles, and then it stays onto the trowel nicely. Just a good strike and push down, like you’re buttering a piece of bread, essentially.
So push that down, you want about that much on there. And what that’s going to do is enable us to get the front and the back and it’ll have something to adhere to. So there you go, she’s ready to go.
So this comes up. We’ll take them away. And then what we’ll need to do is just fill that in, continue on with our bond.
So what we’re going to be left with here will be a three quarter, so the little notch there. Now what I want to do is make sure I’ve got my glasses on because chips can fly up and cause some problems if it hits you in the eye.
So nice and gentle as you’re hitting it. Cracks, and there you go.
Now because I’ve had to lift up the line on those last two bricks, I’ll just check from my level, just on top, which it should be pretty good – and it is.
Just checking through the front as well, that’s no worries.
So now that we’ve laid our first course we need to go back to where we were before so that we get out level line again.
So we’re coming back up to here. So we’ve got one, two, three, four, five again. We go back to our other end and do the same, so we’re sitting here. One, two, three, four, five – level line.
So now that I’m laying this next dummy brick, I can actually lay this so that it’s going to be in bond when I set it in. So what I want to do is make sure that that per underneath is sitting in the middle of this brick, which it just about is right now.
Now I’m just using my eye to eye down the faces, and I will check that but I’ll do that first, and I’ll check, so we’re getting very close now. So this isn’t essential to do this in two courses or in three courses, because we’ve got another five above the line, we’ve got six above this. So if we grab two mm each course we’ll have it by the top. So you don’t want to have a big messy bit at the bottom and then go from there. Okay, so it’s safe to go
down again now.
And as you can see with the spreading here of the mortar, I’m just laying it down. I’m just picking up some excess stuff from the sides, so you get a nice little triangle shape. Then you just go straight through the middle and just feather through it so you get that nice pattern and what that does is it creates that air pocket in there so that it’s nice and easy to lay a brick on it. That’s why it’s called a bed, because that’s the comfort that the brick gets when it sits
down on top.
So there you go. So that’s got us out of the ground. We’re now able to use our gauge at that end, which is right. We’re able to use our already established brickwork at this end. So we’re right to finish off our wall. Five course to go and we’re done.
More often that not we lay half on brickwork so it’s one brick sitting on two bricks. So all the way through it’ll be sitting half on.
Okay, last brick going in now, just as important as the first one. There we go, all done.”
