105-sq ft Flooring Underlayment Membrane
Dimpled HDPE underlayment that creates an air-gap and vapor barrier over concrete slabs for dry, warmer basement floors. Installed dimple-side down, it equalizes vapor pressure and pairs with plywood or can go beneath laminate, carpet, vinyl, or hardwood.
Key Features:
- Moisture Protection: Air-gap design provides a reliable capillary break and vapor barrier over concrete slabs
- Warmer Floors: Built-in thermal break helps basement floors feel warmer and more comfortable
- Tough HDPE Build: Impact-resistant membrane with outstanding compressive strength (>4500 lb/sf)
- Low Profile: Minimal height loss at approximately 8 mm for easy retrofits
- Easy Installation: Lightweight rolls; seams taped with DELTA-MOISTURE PROOF TAPE to block inward moisture migration
