100 X Less Permeable
VIAFLEX Vaporblock® Plus™ 20
Moisture & Vapor Barriers & Accessories
Underslab Moisture and Gas Barrier
VaporBlock® Plus™ is a seven-layer co-extruded barrier made using high quality virgin-grade polyethylene and EVOH resins to provide unmatched impact strength as well as superior resistance to gas and moisture transmission. VaporBlock® Plus™ 20 is more than 100 times less permeable than typical high-performance polyethylene vapor retarders against Methane, Radon, and other harmful VOCs. Tested and verified for unsurpassed protection against BTEX, HS, TCE, PCE, methane, radon, other toxic chemicals and odors.
VaporBlock® Plus™ 20 multi-layer gas barrier is 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. VBP20 is one of the most
effective underslab 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. Available in a 20 (Class A) mil
thicknesses designed to meet the most stringent requirements. VaporBlock® Plus™ 20 is produced within the strict guidelines
of our ISO 9001 Certified Management System.
VaporBlock® Plus™ 20 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 recommended to include a ventilated system with pump(s) that can be converted to an active control system with properly designed ventilation fans.
VaporBlock® Plus™ 20 works to protect your flooring and other moisture-sensitive furnishings in the building’s interior from moisture and water-vapor migration, greatly reducing condensation, mold and degradation.
