Crawl space encapsulation

Encapsulating a crawl spaces is a common solution for avoiding crawl space moisture issues.  Crawl space encapsulation involves installing a heavy-duty polyethylene barrier to completely cover the floors, foundation walls, and sometimes even soffit and floor joists in your crawl space.  The barrier that covers the soffit and floor joists must be semi-permeable to allow the wood structure to breath.

This water vapor barrier is most effective when it completely seals your crawl space.  Seal tape is used to secure the sections of the liner for best moisture and best control.  

Once a crawl space has been encapsulated, the air in the crawl space should be monitored and controlled by adding a dehumidifier to regulate the crawl space’s humidity levels.

This barrier and dehumidifier combination protects the crawl space from excess moisture and all the problems that come along with it.
