damp proofing & insulating basement
I live in a raised ranch with about 3.5 feet of basement below ground. The walls, for some reason, were never insulated and smell very musty. I was going to take down the paneling in this area and clean up the area (there was water in the past so I'll clean any mold/mildew I find) and use the foam panels to insulate the walls between the studs. I was wondering if I should damp proof the cement? There is damproofing on the outside but it looks weak (the house was built in 1969). Is it recommended to dampproof the interior walls (maybe with Thomsons waterproofer) before I insulate? Any advice would be helpful.
