Building a retaining wall

How to build a simple block retaining wall

Are you looking to build a retaining wall made of blocks? Below is a quick tutorial on how to do this yourself at home.

Please note this is for a simple retaining wall up to 0.8m in height from natural ground level. Feel free to also use manufacturer recommended installation guidelines where available. For advice on more extensive projects, please call our friendly team on (02) 9791 1595.

Step 1Level the ground by measuring and layout out the position of the retaining wall. Remove soil as needed (this may require excavation) and create a narrow trench for the bottom of the blocks to sit. You will want to keep some space between the back retaining wall and the earth behind it.

Step 2Lay the base of the wall by applying a porous base – this can be sand or gravel. Spread 2 inches where the base will be laid and even it out. This will promote drainage.

Step 3Set the first few blocks into the base, pressing down firmly. Check the first block is level in all directions by using a level. Continue with the adjoining blocks, checking with a level to maintain the row at an even level.

Step 4Lay the second row in a running bond brickwork pattern. This will increase the durability and strength of the finished product. You will need to cut and fit the blocks at the end. Most of our products come with corner pieces for a neater finish.

Step 5Check the space behind the wall once built. If there is a large set back during the construction, you may require soil to be inserted to minimise the gap. If the gap has been maintained, fill this with a porous backfill such as sand or gravel.

Step 6Evenly insert the backfill and rake and shift in small amounts to ensure no space is left. Once done, you can add topsoil and plant turf or plants if required.
