Radon Barrier
VALPLAN Radon barrier is a membrane made from polyester reinforced thermoplastic polyolefin that protects buildings against radon gas from the ground. The membrane can be prefabricated with all details and accessories or directly installed on site with all needed welding’s to get the system gas tight. All welding’s will be tested on site to ensure the quality. Prefabricated systems can be installed in any weather conditions.
Surface preparation
- The membrane can be installed in the foundation pit on levelled substrate.
- The membrane can be installed on a levelled insulation layer.
- The membrane can be installed on a levelled concrete slab/screed below internal flooring.
What is Radon (Rn 222)
Radon (Rn 222) is a radioactive, invisible, odorless noble gas that it is emitted continuously by uranium. Uranium occurs naturally in many rock types, including alum shale, granite and granitic gneisses. Uranium is radioactive and decays very slowly, having a half-life of four billion years. Over a long period, uranium decays into radon, among other things. Radon further decays into its residual products of bismuth, polonium and lead, with a half-life of 3.8 days. It is the transition from radon to its residual products that is harmful, and high concentrations of radon gas are dangerous for humans.
Installation
It is important for radon protection to be installed by skilled and experienced Teams.
