Radon Barrier 300mu 1200g Gauge 4m x 25m

If you're worried about harmful radon gas seeping into your space, install this radon barrier when building or renovating to prevent it from coming up through the ground. It's suitable for homes and other buildings, and can also be used as an effective damp proof course to stop moisture rising into a structure, which can cause damage over time. 
This Damplas product has been independently tested for resistance to radon gas. It's made from recycled polythene. You can use it in conjunction with most common flooring systems, but don't lay it if there's a risk of hydrostatic pressure. Make sure you store it under some cover, as prolonged exposure to UV light can cause the barrier to become brittle. For installation guidance, we recommend that you consult the most recent edition of Building Research Establishment Report BR 211.
