Dampro Sub-Flooring Underlayment for Concrete Floors 42 in. x 30 ft.

AlinO-Dampro is a dimpled, heavy-duty plastic membrane for concrete and slab-on-grade floors that helps to keep moisture out of your basement. The membrane provides a significantly more comfortable floor. AlinO-Dampro 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. Must be covered with an OSB or plywood layer.

• Waterproof tile underlay ideal to protect home from mould/mildew
• Protect your basement floor from water damage
• Help to maintain your floor temperature due to air gap
