Easi-Load Radon DPC 0.90m x 20m has been designed using thermoplastic co-polymer technology to give effective protection where a radon, air and moisture seal must pass through masonry walls. It is particularly suitable for cavity wall construction and can be used at all floor/wall junctions.

Monarflex Radon Barriers are high quality loose-laid radon resisting membranes made from blends of virgin low density polyethylene (LDPE).
