RETAINING WALLS AND SUBTERRANEAN WATERPROOFING

Good design of a retaining wall must incorporate both adequate drainage, and an appropriate waterproof barrier. Water in the wall can create a number of problems, including weakening the structure, and corrosion of the embedded steel, which in turn causes concrete cancer.

Waterproofing of a wall should be completed externally during construction, and if for a new build, large modification or an engineered design, it should come with a certificate of compliance such as a Form 16 for Queensland.

Water ingress issues with retaining walls can include rising or penetrating damp, running water ingress, mould or excessive calcification.

Repairing small leaks and damp on retaining walls can sometimes be a simple DIY project using readily available materials for a local hardware outlet. Larger jobs can often indicate a more complex solution is required.

 

Negative-side (inside) waterproofing can seal the inside allowing the room to be habitable and moisture free but will not treat the brickwork. Penetrating sealers will also penetrate and seal the brickwork to a certain depth but will not seal the whole brick from moisture. Curtain injection, where a waterproof membrane is injected into the far side of the wall can seal the whole brickwork but may be costly and require several attempts to totally seal the area.
