Bricklaying is considered one of the more approachable construction skills, and many self builders are understandably keen to give it a go. But this isn’t a tasked to be taken on lightly, especially if you’re building structural walls. The easiest route to great results is enlisting a good brickie. Using an experienced tradesman may be cost-effective, too, as it’s likely to speed up the build and minimise mistakes.
If you do want to tackle an involved bricklaying project, it makes sense to practice first. Even the most confident DIYer will need to get to grips with the process first. Trying your hand at building a garden wall is a great place to start. You’ll learn everything from setting out the footprint and maintaining level and square to mixing the mortar, bedding the bricks and finishing joints neatly.
Before you begin your project, you’ll need to figure out the number of bricks required. Standard types are 215mm x 102.5mm x 65mm. To get an accurate picture of the number required for the task in hand, however, you need to account for a 10mm mortar bed. So to come up with the correct calculations, input your brick size as 225mm x 102.5mm x 75mm for standard products.
Brick wall project guide:
After any necessary foundations have been prepared, lay out the bricks at both ends of your wall where the pillars will start. Using your string line, make a straight guideline at brick height between the two outside bricks
Heap five shovels full of sand and one of cement on an old board. Turn shovel to mix to a consistent colour. Form a central hollow, pour in water and mix. Repeat for a smooth, creamy texture that’s wet but not too loose
Lay a 1-2cm mortar bed along the string line. Starting at one end, lay the first brick and tap slightly to ‘bed in’. ‘Butter up’ one end of the next brick with mortar and abut it to the first. Repeat using string line as a guide
At the point where you want your pillars to start, place a brick side-on to the end of the wall. As you build up the wall, each consecutive course of pillar bricks must be laid in the opposite direction
When building pillars, at certain courses you’ll need to lay half-bricks. To make a cut, place the brick on its side, locate the bolster at the split point and strike the head firmly with a club hammer. It should split cleanly first time
Always build at least a course higher on the pillars. Move the string line up as you build, bedding it into the mortar on the pillars. For a stretcher bond, the end of each brick should be over the centre of the one beneath
Vertical mortar joints should be 10mm thick. With standard bricks there should be 75mm from the top of one to the top of that beneath. If your bricks soak up moisture fast, you may want to ‘joint up’ (step 10) as you go
When you reach the top of the pillars, you may want to add a coping stone to finish. Alternatively, you could create a pleasant effect at less cost by bedding bricks into the mortar on their sides
Adding a ‘soldier course’ is an attractive option to top the main part of a garden wall. Turn your bricks vertically lengthways and lay along the full length. Use a second, higher string line to keep a uniform finish
To finish the beds, use the rounded edge of a brick jointer to scrape mortar into the joints. Start with the horizonal lines and follow with the vertical – it’s easier to remove any excess mortar this way
Give the finished wall a gentle brush over and clean up any mortar that has fallen onto the floor before it dries. You can use water to wash cement away from the floor, but be sure to keep it away from your newly-built wall!
