A Few Considerations While Building The Concrete Sleeper Retaining Wall:

One of the most straightforward methods for constructing a retaining wall is using concrete sleepers. In reality, this system is an excellent DIY choice. Other options include timber sleepers, which are lightweight and simple to install but prone to rotting, fading, and white ant damage.

Cement blocks are another excellent option, although they have limitations in that they are not ideal for walls taller than one meter. Compared to concrete sleeper retaining walls, cement blocks are likewise quite difficult to get beautiful and straight.

Where the retaining wall is larger than two meters above natural ground level and is to be positioned within 1.5 meters of a side or rear boundary or six meters of a road border, design and siting relaxation approval from the council is required.

Steps To Build The Retaining Wall:

The basic building steps of concrete sleeper retaining wall are following:

Layout the Retaining Wall Building Area:

Set a string line along the line of the intended retaining wall while drawing out your retaining wall. Set your pegs past the retaining wall’s end so that the holes don’t interfere with your string line. Make a plan for where each hole will be excavated.

Remove any trees, bushes, shrubs, or other obstacles from the area. Ensure the location where the concrete sleeper retaining wall will be installed is level. Measure and mark the areas where the post holes will be dug.

Dig The Holes For Posts:

To dig the holes for the posts, use a mini-loader with an auger. When the concrete sleeper retaining wall is finished, make sure to provide enough space to backfill. Drill your holes to the desired depth. The hole depth should be the same as the height of the wall. Drill holes deeply when utilizing our fence brackets to install a fence to the top of your retaining wall.

Setup The Holes With Concrete:

Ascertain that each hole is level, straight, and of equal depth. When you’ve finished installing the posts, make sure they’re flat with the other holes and spaced evenly. To secure the holes, pour concrete into them. It is preferable to deal with one post at a time, ensuring it is level before moving on to the next.

Make sure the next post is level with the preceding one as you work on it. Check the distance between the posts to ensure they’re all the same distance apart. Allow at least one day for the concrete to set and dry completely.

Install The Concrete Pads And Sleepers:

A concrete pad behind each post allows the sleepers to sit level, resulting in a level concrete sleeper retaining wall. Place a level concrete pad behind each post to establish a level foundation for the bottom sleepers as you go. Allow the concrete pads to cure and dry for at least three days before laying the sleepers on them.

The foundation sleepers should be placed on the pads against the posts. If you didn’t use concrete pads, make sure to pack them flush with the bottoms of the posts to ensure proper height adjustment. To allow any water to escape, place a pipe in the back and base of the wall. Allow one week for the wall to settle before backfilling.

Use Crushed Rocks And Gravel To Refill The Wall:

Backfill the concrete sleeper retaining wall with crushed rock to complete the project. Only fill the bottom sleeper to the top. Backfill with dirt after inserting a soil plug. Make sure you just place the mud or fill on top of the wall, not behind it. To make the process easier, you can move the dirt by hand or with the help of a Bay lynx or other machinery.

It’s also crucial to backfill lightly rather than dumping from a considerable height. Although concrete sleepers are built to withstand the soil strain behind them, compacting directly behind the wall is not recommended. As a general guideline, never condense any closer to the wall than its height. Therefore, machinery should stay at least 1m away from a 1m wall.


Hopefully, this post will provide you with the guidelines and instructions essential to building the concrete sleeper retaining wall yourself. No doubt, you can also hire a professional contractor for this building project. But professional services maybe cost you more than your budget. That’s why it is better to opt to build this wall yourself by considering the discussed steps and information.
