Radon Block™, High Performance Radon Blocking Barrier Membrane

Radon Block™ is the new leading high performance radon blocking barrier membrane. Radon Block™ resists gas and moisture migration into the building envelope, providing superior protection from toxic and harmful chemicals.

Product Description

Radon Block™ is a seven-layer co-extruded barrier made from state-of-the-art polyethylene and EVOH resins to provide unmatched impact strength as well as superior resistance to gas and moisture transmission. Radon Block™ is a highly resilient underslab/vertical wall barrier designed to restrict naturally occurring gases such as radon and/or methane from migrating through the ground and concrete slab. Radon Block™ is more than 100 times less permeable than typical high-performance polyethylene vapour retarders against methane, radon and other harmful VOCs.

Radon Block™ 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. Radon Block™ is produced within the strict guidelines of an ISO 9001:2008 Certified Management System.

Product Use
Radon Block™ resists gas and moisture migration into the building envelop 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 recommended to also include a ventilated system with sump(s) that could be converted to an active control system with properly designed ventilation fans.
Radon Block™ works to protect your flooring and other moisture-sensitive furnishings in the building’s interior from moisture and water vapour migration, greatly reducing condensation, mold and degradation.
