Occasionally(every year or so) our basement
floods. I added a sump pump over a year ago and
it may have fixed the problem(we haven't had a flash flood in a while).
What is the best type of water proof wall board
to use? I am considering green drywall board
which is water resistant. Note that when the
basement does flood, the highest it's ever been is about 4 inches, so, only the first 4 inches is what needs to withstand water. Also, the flooding usually only lasts about an hour before it goes away. I think that I can place
a water proof material on the wall for the first several inches or so...then regular drywall.
4" of water and there's a pump in the basement? Consider locating the pump on the lowest spot on the floor so the water will go into the sump. Also what kind of pump is it? If it is of the garden hose variety it may not be pumping out the water as fast as it comes in. Fix this first then drywall. C.
