Wood basement drainage?
My understanding is that very well executed drainage is vital to the success of a PWF basement.
The designs I've seen typically have a crushed rock or washed gravel layer under the basement's walls and floor, 4" or 6" thick. They also backfill at least 1/2 way up with the drain rock. My questions are: Would a 1" layer of Roxul " Drain Board be a proper replacement for the back fill rock? Is filter fabric on the outside of the wall's drainage medium needed?
