Water Penetration from Porch into Basement
The people who renovated our house before we bought it, installed a porch with tongue and groove slats right over the basement. Recently, we noticed water on the walls, floor, and insulation of the basement. Turns out, water is dripping right through the tongue and groove slats if there is any more than a light rain outside, or if we decide to water the plants that are on the porch.
What are the options here? Take the whole porch apart and lay a waterproof membrane?
