What is a Concrete Sleeper Retaining Wall?
Concrete sleeper retaining walls, also known as cantilever post retaining walls, are a reliable and long-lasting solution for residential, commercial, and civil projects across Bacchus Marsh, Geelong, Ballarat, and Melbourne.
Designed to maximise usable land space thus, these retaining walls deliver exceptional structural integrity, low-maintenance durability, and excellent value over time.
Ideal for sloping sites or areas with restricted access, cantilever post walls combine engineered strength with design versatility and a modern, streamlined appearance.
Whether you’re planning domestic landscaping, a property boundary wall, or a large-scale infrastructure project, concrete sleeper retaining walls offer dependable, long-term performance built to withstand the elements.
How it Works
The term “cantilevered” means the post is anchored at the base and extends upward, supporting the wall by resisting pressure from the retained soil. The pressure from behind the wall is transferred into the ground through the concrete footing and the rigidity of the post.
Key Components
Steel Posts: Embedded deep into a Concrete foundation.
Footings: Concrete-filled holes that secure the posts in the ground.
Sleepers/Panel: Inserted between the steel posts to retain soil.
Drainage: Inserted below the drain rock behind the wall.
Advantages
Strong and durable — designed to handle heavy loads.
Space-efficient — ideal for boundaries or tight areas.
Modular — easy to customise with different materials or finishes.
Cost-effective — especially for mid-height walls (typically under 2.4m).
Common Applications
Residential landscaping – Create level gardens, terraces or usable space.
Property boundary walls – Strong, long-lasting privacy and structure.
Driveway retaining walls – Retain soil and support vehicle load areas.
