Hello,
I have heard different opinions on the use of gravel along with a poly
6mil vapor barrier. I am trying to conclude what the best solution is to control the moisture in my crawl.Here is what im working with:
1950's Cape Cod, Brick, 5' crawl (approx 1200sq feet). The ground is mostly soft dirt, mostly dry but the furnace is down there on blocks approx 2-3 feet off the ground, so its been running alot this winter and we just bought the house. There is a sump pump that is located in the crawl.I have purchased 6mil Poly sheets to cover the crawl but have not installed yet.
My question is will just the poly sheets be enough to keep moisture down and prevent mold, or do I need to put some kind of stone either under or over the poly?
If so what size stone, how much (thick) etc... OR will it even help much one or the other...
Any suggestions or expierence is appriciated!
Jason
