moisture barriers
Damp-blocking membranes installed
Moisture barriers are materials designed to prevent water or water vapor from passing through walls, floors, or other surfaces.
In construction, they protect buildings from humidity damage, mold, and rot: We installed a moisture barrier before laying the flooring.
The term applies to plastic sheeting, specialized paints, membranes, and similar products used in basements, crawl spaces, and behind siding.
