Are WoodBlocX retaining walls freestanding?

No! WoodBlocX retaining walls include buttresses behind the wall which act as cantilevers under the weight of soil, keeping the main wall structure supported and strong.

Buttresses will always finish one layer below the main height of the structure to ensure they are not visible once the structure is built.

Buttress supports are usually spaced 1.5m apart for maximum strength and are normally used in structures larger than 2 metres in length and above 25cm in height.

The depth of buttresses depends on the length, width and height of your wall. When building a wall over 55cm in height, the maximum buttress depth required is 75cm. Lower retaining walls will need less clearance due to shorter buttress size being used in the design.

To ensure you have sufficient space behind your retaining wall for buttresses, we recommend you use our Free Design Service to receive a detailed drawing of your required wall size.
