Loose laid sheet membrane system designed to protect buildings against the ingress of methane, radon, carbon dioxide, hydrocarbon vapours and water vapour. The multi-layered laminate structure gives good strength, flexibility and installation properties. The upper surface of the membrane is coloured green.

Features and benefits:

• Fully compatible with Preprufe and Bituthene membrane systems to form an integrated waterproof and gas resistant protection system.
• Prevents the transmission of methane, radon and carbon dioxide gases.
• Resistant to hydrocarbon vapours.
• Fully bonded lap system.
• Robust – resistant to on-site damage.
• Good puncture resistance.
• High tear and tensile strength.
• Flexible – can accommodate normal building movements.
• Weldable.
