Crawl Space Moisture Control - CleanSpace - A Heavy Duty Vapor Barrier
Replacing the vapor barrier with this 20-mil CleanSpace Vapor barrier is going to protect the crawl space from the earth's moisture. CleanSpace is a heavy-duty liner durable enough to withstand service persons crawling and working in this crawl space, and it's overlapped and sealed at all seams, wrapped and sealed around all piers, and attached to the foundation walls about 6 inches above outside grade to seal the crawl space from the ground's moisture.
