Crawl Space Repair - CleanSpace Vapor Barrier

A heavy-duty CleanSpace vapor barrier has been installed over the dirt flooring of the crawl space. It gets wrapped around all piers, sealed with vinyl tape, and mechanically fastened to the foundation walls six to eight inches above outside grade. When properly sealed, this 7-layer polyethylene liner helps prevent the earth's moisture from rising into the crawl space and increasing the relative humidity.
