Concrete sleeper and galvanised steel post retaining wall systems built across Sydney. A durable, consistent finish with none of the problems that come with timber.
Concrete sleeper walls have become the go-to retaining solution across Sydney for good reason. The system is straightforward: galvanised steel H-posts are set into concrete footings at regular centres, and precast concrete sleepers slot between them to form the wall face.
The result is a wall that holds its shape, resists weather, and looks the same in twenty years as it does on day one. No rot, no termite risk, no warping. We install concrete sleeper walls for everything from simple garden terracing to engineered boundary walls retaining several metres of soil.
All walls over 600mm in retained height are designed by a structural engineer to AS4678 and built with proper drainage and footings.
We recommend concrete sleeper systems for most residential retaining applications. Here is what makes them a strong choice.
We build concrete sleeper walls across a wide range of residential and commercial sites in Sydney. The system adapts well to most situations where soil retention is needed.
Every concrete sleeper wall we build over 600mm retained height is engineered to Australian Standard AS4678. We coordinate the structural engineer, prepare council submissions where required, and build to the certified design.
Post spacing, embedment depth, footing size, and sleeper thickness are all specified by the engineer based on retained height and soil conditions.
Ag-pipe drainage behind the wall with geotextile fabric is standard. Proper drainage prevents hydrostatic pressure build-up, which is the primary cause of wall failure.
Walls near boundaries or over certain heights require council approval. We manage the CDC or DA process and coordinate inspections through to completion certificates.
