I have a 82 yr. old covered porch tongue and groove floor over a basement. There are periodic water leaks into the basement and the borads are rotting and buckling and need replaced.
What is the best way to install a new floor and have it waterproof? The original floor just looks to be a 1x8 base with the 3/4" T&G flooring. There is 2 1/4" between the joists and the bottom of the front door.
Any help is appreciated!!!
