Keep Moisture Out & Basement Floors Dry with Justin Wilson

Basements have transformed from simple storage areas to valuable extra living space that owners can utilize in a variety of ways. From bedrooms to home theaters to home offices, more time and effort is being spent in this area of the home.

With basements being built deeper into the ground, issues with water management and the importance for moisture control become greater. Although moisture barriers are installed on the walls, they are often not installed on top of the footing. By installing an underlayment, you can ensure your basement is completely moisture proof and sealed from the elements – if it’s done correctly.

Demonstrating with a simulated slab, Justin Wilson of Construction Instruction explains how DELTA®-FL protects basements from moisture, what issues can arise when building directly above a sand or dirt layer, and the physics behind moisture control.

DELTA®-FL is a dimpled, heavy-duty High-Density Polyethylene membrane that is completely impermeable. DELTA®-FL provides a capillary break and vapor barrier which acts as a magnet, attracting moisture that rises through the concrete. This air space pushes the water and moisture back into the slab, leaving the above flooring dry. This membrane also provides a thermal break, making the flooring warmer and more comfortable.
