A Moisture Barrier is the installation of an vapor barrier on the ground surface of your crawl space. It differs from an encapsulation in that the barrier stops at the walls and does not run up the walls of your crawl space. A moisture barrier installation also does not require the installation of door and vent covers and will don't include the installation of a dehumidifier..
When is a Moisture Barrier Needed?
It is often required to meet the minimum standards of ventilation when a home is being sold or refinanced and required by a VA loan or financial institution.
When floor damage is non-existant and a full encapsulation isn't immediately necessary. ***
***It is still highly recommened to fully encapsulate to completely seal and protect your foundation and home from moisture damage
