I have a wet basement. Concrete floor (no water coming up through) and block walls, water is coming in in various places, especially corners.
I have a quote of $6600 for an interior french drain/sump system with plastic membrane on the walls (lifetime warranty) but this doesn't stop water from coming in. There is no way to get an excavator in my backyard and no way to dig a trench along part of the back of my house where water does come in.
I wanted to use the bsmt as a music room but am very concerned about humidity since water will still come in. I know parging just masks the problem and redirects water, resulting in new leaks.
The house is on a hill but the back yard is pretty flat. Is grading an option? I have no idea what to do. Help?
