Vapor Barriers: Control Moisture and Protect Your Basement
Vapor barriers are moisture-resistant membranes installed on basement walls and floors to control humidity, prevent condensation, and inhibit mold growth.
Even when there is no liquid water intrusion, basements can suffer from high humidity caused by moisture vapor passing through porous concrete walls and floors. This moisture promotes mold growth, damages stored belongings, and creates uncomfortable living conditions.
A vapor barrier is a heavy-duty polyethylene or reinforced membrane applied directly to the wall or floor surface. It blocks moisture vapor from passing through the concrete and into your living space, reducing humidity and creating a healthier environment.
Vapor barriers are often used in combination with interior drainage and dehumidification systems for comprehensive moisture control. In Colorado, where humidity can swing dramatically between seasons, a vapor barrier provides consistent year-round protection.
