Retaining Walls

Why build a retaining wall?

Retaining walls can help property owners maximise usable land. A retaining wall is specifically designed to support soil and maintain ground which would otherwise drift down. Your retaining wall can define areas within your landscape, prevent soil erosion and maximise usable space by creating shelves of flat land on an otherwise sloping property.

Does my retaining wall need to be engineered?

Each State/Territory and Council have their own regulations on when you need to get your retaining wall engineered. In QLD, the State and most Council requirements do allow for retaining walls up to 1.0m high without being engineered. However, you still need to satisfy the other requirements.
