Gas tight and strong
Protan RadonSafe is a radon membrane made from polyesterreinforced thermoplastic polyolefin that protects buildings against radon gas from the ground. The membrane is joined by means of hot-air welded overlaps, ensuring a gas tight seal. It can be installed all year round, in any weather.
We can prefabricate the entire membrane to fit the building's footprint on request in order to make installation as fast as possible. The membrane comes with prefabricated details and accessories that make it easy to seal complex structures properly during installation.
Protan Radon Safe can be installed for radon protection for all user groups A, B and C.
Solution A: The membrane is installed in the foundation pit on a levelled base
A radon sump acts like a drain, removing water during the construction period and any radon extracted during the life of the building.
Protan RadonSafe has accessories that ensure that tricky details are easy to seal during installation.
RadonSafe details we offer:
- Prefabricated inside corner in radon membrane
- Prefabricated outside corner in radon membrane
- Prefabricated pipe penetrations in radon membrane, in several sizes
- Radon extractor
- Radon sump
- Radon sealant
Sinister noble gas
Radon (Rn 222) is a radioactive, invisible, odourless 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.
The radon gas takes the path of least resistance, so it is important for radon protection to be installed by skilled and experienced tradesmen.
