Building a retaining wall with sleepers is not difficult to install by yourself, but a few considerations need to be taken into account.

Ensure that you’re aware of your local council regulations prior to beginning your build as there will be maximum heights you can build before a building permit and engineering is required.
- Prep the Site – Clear the site area of any shrubs, trees, bushes, or other obstructions. Then, layout only the bottom row of concrete sleepers and use a string to ensure everything is level. Leave about 200mm behind the wall where you’ll need to backfill.
- Dig the Holes – If you are using posts, install them right in the centre of each sleeper. Mark the positions clearly and then dig holes that are as deep as the height of the retaining wall to ensure it is strong.
- Set the Posts – Start with one hole at a time. Fill the hole with concrete and insert the steel post into it. Using the stringline and a level, make sure it is straight and level. Start with the corner posts first and work your way along, ensuring your spacing is kept even throughout by measuring as you go.
- Insert the Sleepers – Let the post holes concrete cure and set for a couple of days before you slide the concrete sleepers into position. If the ground is not level, you can place concrete pads between posts to ensure the sleepers are stacked evenly.
- Agi Pipe and Backfill – Place an Agi pipe at the base of the back of the retaining wall to allow the water to leave and backfill using a gravel designed for backfilling. Fill it only till the top of the bottom sleeper. Then, put a soil plug and again backfill with dirt.
