My partially completed house has a crawl space on 10 feet because the septic tank is ten feet from the foundation.
I pulled up the plywood sub-floor in the bathroom over the crawl space. Underneath is a slab on grade. Floor framing is 3 inches off the slab on PT sills.
6 inches of insulation in the floor. When I pulled the insulation out it was musty and quite damp. The house is on the coast of MA a very humid area.
How can I stop this moisture? I have a couple of ideas.
1) Seal the slab with a masonry sealer.
2) Ventilate the space into the full basement using a fan pulling out and one pushing in. Full basement needs a dehumidifier running all summer.
3) Insulate on top of slab with 2 inch foam insulation panels.
Any help would be appreciated.
