Multi-layer membrane against radon and methane gas. Damp-proof barrier for ground-bearing floor slabs.
DELTA® radon barriers
Radon is a natural, invisible and odourless radioactive gas that rises from the ground into cellars and homes. Long-term exposure can cause lung cancer. A radon barrier under the floor slab stops the gas getting in.
Check your area on the map below, then choose the membrane that suits your build-up. In Ireland, a yearly average of 200 Bq/m³ or more means you should act.
