Crawl Space Moisture Control - Unsealed Vapor Barrier
An unsealed, flimsy vapor barrier does not help protect the crawl space from water infiltration or vapor. Instead, it enables it. 6 mil vapor barriers are often staked down creating more holes and weak points in the system. Heavy duty liners like 20-mil CleanSpace are durable enough to be sealed to the wall and sealed around piers keeping water and moisture out of the crawl space.
