Retaining walls in The Oaks
The Oaks and Oakdale are rural communities on the western side of the shire, with acreage, farm sheds and long driveways. Retaining here is often about driveway batters, shed pads and terraces on large, sloping lots.
What to know before building a wall in The Oaks
On acreage, the scale of the job is usually bigger and access for excavators is easier, which suits sandstone blocks and longer runs of concrete sleepers. Drainage design matters more on long walls, where a lot of water can collect behind the face.
Popular wall types in The Oaks
The most common requests we see for The Oaks are sandstone retaining walls and sloping block excavation and site cuts. Whatever the material, a wall that lasts needs bored footings sized to the wall height and soil, and ag-pipe and gravel drainage behind the face.
Typical cost in The Oaks
As a guide, supply and installation of engineered steel-post and concrete sleeper retaining walls typically ranges from $450 to $750+ per square metre of wall face, depending on site access, rock excavation, drainage and whether a fence is mounted on top. The builder will give you an itemised quote after a site measure.
