Concrete sleeper retaining walls are the most commonly installed retaining walls in Adelaide, providing the strength and durability to withstand heavy earth masses and Adelaide's highly reactive clay soils.
Our retaining wall constructions feature robust 60MPa concrete retaining wall sleepers fitted between heavy-duty galvanised I beam and C channel posts.
Each post is installed into 450mm wide concrete footings at a depth that corresponds to the height of the retaining wall, plus another 100mm, e.g. a 1.0m high retaining wall will require a post depth of 1.1m
The deep posts and large footings of concrete sleeper retaining walls arguably provide the strongest and best valued residential retaining walls in Adelaide.
Concrete sleepers are available in a range of textures including, plain, bookleaf, rock face and timber, with a colour range of plain,charcoal and sand stone
Available in standard sizes of 2000x200 and 2400x200 with a range of thicknesses, 75mm standard, 100mm heavy duty and 120mm extra heavy duty.

Concrete block retaining walls are an excellent choice for those seeking strength, versatility, and fantastic visual appeal Available in a variety of sizes, colours, and textures, concrete blocks are perfect for numerous applications, including the construction of steps, borders, garden beds, and curved retaining wall installations.
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 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 wall installations are built on a solid, two-layered base constructed 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 concrete sleeper retaining walls remain top quality for decades.
Retaining Wall Steps and Retaining Wall Drainage Systems
Retaining Wall Steps
Most split level retaining wall constructions will require steps to gain access to upper or lower tiers. The design and placement of those steps can greatly impact both the usability and visual appearance of your property.
We can install a variety of steps to both concrete sleeper and concrete block retaining walls which best suit your needs including, inset steps, outset steps, wide tiered steps and open ended steps that provide feature and charm as well as functionality.
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. Therefore, it is crucial that all retaining wall installations built 600mm high and over, are equipped with an effective drainage system that allows for the quick release of water from behind the wall.
An effective drainage system for Adelaide retaining walls 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 concrete sleeper retaining walls, 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.
