Delta-Protec Basement/Slab Underlayment 100 sq.ft.

Delta-Protec Basement/Slab Underlayment 100 sq.ft.

To turn your basement into a usable, livable space, proper moisture protection is necessary. Moisture barriers are often installed only on the walls of a basement and not the floor. Moisture diffuses from the area of high concentration below for the floor slab, to the low area of concentration in the basement. 

DELTAź-PROTEC is a dimpled, heavy-duty, green plastic membrane for basement and slab-on-grade floors that helps to keep moisture out of your basement. The membrane provides a significantly more comfortable floor.

DELTAź-PROTEC protects sensitive materials by providing a reliable capillary break and vapor barrier. In a conventional basement, dry air in the living space acts as a "magnet" for water vapor migrating up through the concrete. The air gap created by DELTAź-PROTEC allows the water vapor pressure above and below the concrete slab to equalize, while preventing the moisture from migrating further inwards. Hence, moisture does not affect the flooring material and your basement area stays dry and comfortable. The membrane also provides a thermal break, which increases the comfort in your basement and makes the floor feel warmer.

Product Details:
- Air-gap membrane
- Composed of a special High-Density Polyethylene (HDPE)

Product Benefits:
- Provides a reliable capillary break and vapor barrier, ensuring a dry, livable basement.
- Creates a thermal break, making a basement floor feel warmer.
- Impact-resistant HDPE makes this product extremely tough and rugged.
