We replaced the vapor barrier within this Midlothian crawl space. The problem with the existing vapor barrier was that it had many gaps and holes within it, allowing the earth's moisture to rise into the crawl space. The moisture that becomes trapped within the crawl space will raise the relative humidity levels, leading to condensation in certain temperatures, and even mold or mildew growth. We replaced this inadequate liner with our own CleanSpace Light vapor barrier. The CleanSpace Light is a 10mil liner that covers the entire dirt floor of the crawl space, gets wrapped around each pier, and is mechanically fastened to the foundation walls six to eight inches above outside grade. A two-inch viewing strip is left at the top of the foundation walls for termite inspectors. This high-quality vapor barrier will help to reduce the earth's moisture from affecting the relative humidity of the crawl space, and it gives a bright, clean aesthetic to the crawl space.
