Sealing Up a Louisa, VA Crawl Space Floors

These homeowners in Louisa wanted to encapsulate the crawl space on their newly constructed home. The exposed dirt flooring of the crawl space would continue to allow the earth's moisture to rise into the crawl space unless covered and sealed. The moisture rising from the earth can increase the relative humidity of the crawl space, which can then lead to mold growth, condensation, and moisture damage to certain materials. We placed a 10-mil CleanSpace vapor barrier over the dirt flooring to help protect the crawl space from the rising moisture. This liner gets wrapped around all pillars and is mechanically sealed to the foundation walls six to eight inches above outside grade. Any seams and gaps are sealed with a unique vinyl tape. The vapor barrier will help to prevent moisture from elevating the relative humidity, and it gives the crawl space a brighter and cleaner aesthetic.
