High-Barrier Co-Extruded Concrete Under-slab Films Designed to Meet the Most Stringent Requirements
CNG concrete under slab film is a multi-layer co-extruded barrier made using high-quality virgin-grade polyethylene and EVOH resins to provide unmatched impact strength and superior resistance to gas and moisture. CNG under slab films are more than 100 times less permeable than typical high-performance polyethylene vapor retarders against methane, radon, and other harmful VOCs. Tested and verified protection against BTEX, HS, TCE, PCE, methane, radon, and other toxic chemicals and odors.
Technology Applications:
Radon Barrier
Methane Barrier
VOC Barrier
Brownfields Barrier
Vapor Intrusion Barrier
Underslab Vapor Retarder
Foundation Wall Vapor Retarder
Charter next generation Under-slab Films
Under-slab films are manufactured with the latest EVOH barrier technology to mitigate hazardous vapor intrusion from damaging indoor air quality and the safety and health of building occupants. CNG’s under-slab film is one of the most effective under-slab gas
barriers in the building industry today, far exceeding ASTM E-1745 (Plastic Water Vapor Retarders Used in Contact with Soil or Granular Fill Under Concrete Slabs) Class A, B, and C requirements.
Product Use:
CNG concrete underslab film resists gas and moisture
migration into the building envelope when properly installed to provide protection from toxic/harmful chemicals. It can be installed as part of a passive or active control system extending across the entire building, including floors, walls, and crawl spaces. When installed as a passive system, it is also recommended to include a ventilated system with
sump(s) that could be converted to an active control system with a properly designed ventilation fan.
