Features:
DELTAŽ-FL on concrete floors protects sensitive materials by exploiting the concept of vapor pressure - that is, water vapor seeks to equalize its pressure by moving from areas of high pressure to areas of low pressure.
In a conventional basement, dry air in the living space acts as a magnet for water vapor seeping up through the concrete. But with the DELTAŽ-FL system, the space between the dimples provides a sufficient air-gap to equalize the water pressure above and below the concrete slab.
Though the air in the living space is completely isolated from the system, DELTAŽ-FL is designed to allow small amounts of water vapor into the room to maintain a healthy humidity level.
The membrane also provides a thermal break that generates instant comfort and warmth for your basement. DELTAŽ-FL is an inert material. The air-gap membrane has an outstanding compressive strength of > 250 kN/m˛, is extremely tough and rugged and can withstand heavy loads which allows for any finishing on top of the membrane.
The reduction in head room is minimal and the product is extremely easy and fast to install. DELTAŽ-FL comes with a 20 year product warranty.
DELTAŽ-FL functions in conjunction with wood laminate floors and is a simple new solution to create a beautiful, high-performance basement floor, easy enough for the average homeowner to install.
Once DELTAŽ-FL and plywood sheets are laid out, a variety of floor coverings can be installed:
- carpeting with rubber underlay
- linoleum (on top of multiply board)
- peel & stick
- hardwood flooring
- laminate floors (floating directly on top of DELTA-FL)

Application:
DELTAŽ-FL functions as an effective vapor barrier in conjunction with wood laminate floors and many other common floor coverings, and is a simple new solution to create a beautiful, high-performance basement floor.
The leight-weight product comes in two different roll sizes, as well as easy-to-handle sheets. It is fast and easy enough for the average homeowner to install.
Once DELTAŽ-FL and plywood sheets are laid out, a variety of floor coverings can be installed:
- laminate floors (floating directly on top of DELTAŽ-FL)
- carpeting with underlay (on top of plywood board)
- vinyl flooring (on top of plywood board)
- hardwood flooring (on top of plywood board)
Seams are simply taped with DELTAŽ-MOISTUREPROOF TAPE to ensure that moisture cannot migrate inwards through the joint areas.
