Damp proofing
A dry basement you can actually use
Cellars and basements sit below ground, so water in the surrounding soil is constantly pressing against the walls and floor. Without waterproofing that moisture comes straight through, which is why so many basements smell musty and cannot be used for anything that matters.
Tanking solves this by creating a waterproof barrier. Depending on the room we either apply a cementitious tanking slurry directly to the walls and floor, or fit a cavity drain membrane that channels any water away to a drainage point. We survey the space, explain which system suits it and provide you with a written quote. Done properly, tanking turns a damp cellar into dry, useful space you can convert or live in.
