Structural retaining walls can be built out of various materials including
- Boulder walls
- Besser Blocks
- Interlocking dry stack walls
- Brick(face render bagged)
- Common walls with stone faced flagging
- Treated pine timber
Engineer plans should be drawn up for walls over 1 meter to ensure
structural integrity. If so work is carried out to the plans
specifications. Concrete footings are poured with steel bars
incorporated for strength.
