Radon barrier
Application
For use on sites with radon gas.
Description
A flexible, loose-laid gas barrier for use on sites with radon gas.
The barrier incorporates a three-layer low density polyethylene membrane with a polypropylene reinforcement grid. The membrane is extremely flexible for ease of installation and robust to cope with site conditions.
Features and benefits:
- Resistant to radon gas.
- Protects against water and water vapour, acting as a damp-proof membrane (DPM).
- High resistance to tearing.
- Can be laid on sand blinding, Delta Protech Geotextile Protection fleece or a smooth concrete finish.
- Can be patch repaired.
- Laps can be joined together either by using a 50 mm Delta Gas Barrier butyl tape or welding by on-site contractors.
- CE-marked and BBA-certified.
