Waterproofing & Tanking

Cavity drain membranes are made of high-density studded polymer sheets which can be placed against the internal face of a structure after construction and are designed to intercept water penetrating the structure and direct it to a drainage system.

Tanking is the application of an appropriate waterproofing barrier to the walls, the base slab and where relevant, the roof of a below ground structure so that the entire envelope of the below ground structure is protected against water ingress.
