Crawl Space Encapsulation Northern VA

Encapsulated Crawl Space Polyethylene Vapor Barrier Example of Encapsulated Crawl Space Vapor Barrier installed in a crawl space

Water and moisture are constant problems with crawl spaces. Even when water/moisture is removed from a crawl space, it is only a temporary solution and will last a short period of time. Eventually, the soil will become re-hydrated, and water will once again collect inside of your crawl space until the  issue has been resolved. Luckily, Foundation Medix has a permanent solution to stop water from damaging your home.


With crawl space encapsulation, the crawl space is covered with a 20 millimeter reinforced polyethylene vapor barrier, which completely prevents water vapor from flowing above the soil and/or from foundation walls. This process directs water to a specific location for collection and draining. Lastly, at the drainage point, we install a sump pump to remove any excess water. It is expelled through a drain pipe at a minimum of five feet from the foundation walls.

Thecrawl space encapsulation water vapor barrier solution is not only affordable, but it is also extremely durable and puncture resistant. The vapor barrier is 300-600% thicker than a standard plastic vapor barrier a typical builder might install.  Additionally, to ensure that all seams are sealed airtight, we utilize specialized high strength tape specifically designed for this application.
