I am starting to finish my basement, and would like to get some opinions regarding the various types of subflooring products. I plan to use Pergo type, or similar, finished flooring. Moisture retention and mold prevention are important. DriCore looks interesting, but if it gets wet could it be a problem? Would I be better off using something like Tyroc, or DeltaFL, products that are inorganic and thus won't absorb water? I read an article in Fine Homebuilding #169 pages 78-83 that suggested laying 1" EPS rigid foam directly on the concrete floor, then sealing it, followed by 2 layers of plywood. This doesn't seem to allow adequate air circulation between the concrete floor and the subfloor. Also, what would be the best way to wall over the poured concrete walls? That article also recommended installing 2" EPS directly on the walls, then putting up wood studs. Also, should I do floor first, then walls? Any advice for this newbie would be appreciated.
