Concrete sleeper retaining walls are the most popular choice for retaining wall installations in Adelaide, offering the strength and durability needed to endure heavy earth masses and the region's highly reactive clay soils.
These concrete sleeper retaining walls are built using robust 60MPa concrete retaining wall sleepers, securely fitted between heavy-duty galvanised I beam and C channel posts.
Each post is installed into concrete footings at a depth that matches the height of the retaining wall—so, for instance, a 1.0m high retaining wall will require a post depth of 1.0m, necessitating a 2.0m post.
The deep posts and substantial footings are essential to the stability and strength of concrete sleeper retaining walls.
Available in standard sizes of 2000x200x75 and 2400x200x75, as well as specialty 2340x200x75 sleepers that allow for the installation of Good Neighbour Fencing, these concrete retaining wall sleepers come in a range of finishes—plain and decorative—in natural, sandstone, and charcoal colors designed to enhance the visual appeal of your home.

Concrete block retaining walls are an excellent choice for those seeking strength, versatility, and fantastic visual appeal. Available in a variety of sizes, shapes, colors, and textures, concrete sleeper retaining walls are perfect for numerous applications, including the construction of steps, borders, garden beds, and retaining walls with curved designs.
Unlike the large solid blocks used in commercial settings, most blocks produced for residential retaining wall installations are hollow. The overall height and durability of the wall depend on the construction methods and core filling materials employed during the retaining wall installation. To ensure the unwavering strength, stability, and visual appeal of our Adelaide retaining walls, we implement a range of construction techniques that exceed manufacturer recommendations.
All retaining walls are built on a solid, two-layered base made up of compacted rubble and a 32 MPa concrete footing. Additionally, we can incorporate both horizontal and vertical reinforcing, concrete core filling, heavy-duty adhesives, and the necessary backfill and drainage systems to ensure that the strength, stability, and visual appeal of our retaining walls remain top quality for decades.

Retaining Wall Drainage System
A competent drainage system for Adelaide retaining walls is essential to prevent damage caused by the buildup of hydrostatic pressure and the expansion of wet reactive clay. The pressure applied to concrete sleeper retaining walls in these wet conditions is three times greater than that of dry soil, potentially leading to cracking, tilting, and complete failure of the structure. It's crucial that all retaining wall installations built 600mm high and over are equipped with an effective drainage system that enables the quick release of water from behind the wall.
An effective drainage system should include:
- Coarse aggregate used to create a 250-300mm thick layer of permeable backfill that facilitates the movement of horizontal water vertically down the wall.
- A plastic film and a slotted agricultural pipe running along the base of the retaining wall, capturing this water and directing it to a release point under the wall.
- At the release point, the agricultural pipe should be connected to either a French Drainage system or the existing stormwater system of the property for safe removal to the street or easement.
