We have a daylight block basement that we sealed on the outside w/ rolled on cement, and then rolled on 3 coats of foundation/roof sealant. These blocks will be filled w/concrete & rebar. To protect this black foundation/roof sealant stuff and to isulate the blocks somewhat we are going to place 1/2" styrofoam along the walls before we backfill.( Our block mason told us to seal w/ rolled on concrete & foundation/roof sealer.)?1 Is this foundation/roof sealer,(comes in 5 gal buckets), suitable? ?2 Is use of this 1/2" styrofoam a good idea? ?3 should we roll on conrete on the inside of the basement? I had a related question on drain tile but decided to break up my questions about the dreaded basement wettness battle.This basement will have an 8' covered deck on the backfilled sides to help with water management.
