I've just asked a builder for a quote on damp proofing a basement. The basement is in a house on a hill. One wall has earth behind it, two side walls are shared with next door, and one wall is at garden level with a window and door out.
We want to make the basement habitable and into a kitchen. The builder has suggested aquaseal and dry walling all round on the walls and asphalt on the floor.
How does this sound?
I wanted to get some opinions if anyone is happy to offer them. I wonder about dry walling and aquaseal as he is proposing nailing the membrane on and this will make holes. I wonder about the asphalt floor and why he hasn't suggested a plastic membrane and concrete. I am also concerned that the methods proposed does not seem to be a 'system' ie, a partial 'tanking' of the basement.
The basement does not appear to have a damp problem other than the usual damp air feel of an unused basement but I am concerned over the limits of his proposals.
How long/against what can i expect it to be effective?
