How to Install a Vapor Barrier in a Crawlspace ~~ This article will show you how to add 6 mil plastic sheeting on the ground and insulate the walls in your crawlspace. We use foil-faced rigid insulation to keep the space under the house dry. The plastic and the insulation will eliminate any moisture problems you have in the crawlspace, such as water droplets collecting on the concrete walls and pipes.
The problems in a house with a crawlspace—mold, wood rot, pests, cold floors, buckling hardwoods—all can be linked back to moisture problems in the crawlspace. The old school of thought of adding more vents to circulate outside air through the crawlspace does not fix the moisture problems but actually makes them worse.
