BITUTHENE® MRX
Methane and radon gas resistant, self-adhesive membrane
Product Description
BITUTHENE® MRX is a methane, carbon dioxide and radon resistant grade of BITUTHENE® specifically designed to resist these harmful gases. BITUTHENE® MRX has a specially developed high strength composite backing film laminated to self-adhesive polymer compound designed to resist the passage of harmful gases.
Product Advantages
- Resistant to passage of methane, carbon dioxide and radon gas
- Gas resistant - methane, carbon dioxide and radon gas protection in excess of the standard membrane requirements in BRE Reports 211 (radon) and 212 (Methane and carbon dioxide)
- Water and vapour proof
- Laminated metal foil/polymer - provides dimensional stability, high tear strength, puncture and impact resistance
- Single layer - simple, reliable, low labour cost
- Cold applied - no heating plant required, eliminates fire hazard
- Self-adhesive - continuity at rolled overlaps, polymer formulation allows for healing of small punctures
- Factory controlled thickness - no variation by site practices.
Application
Recommended priming application temperature +5°C to +35°C Apply BITUTHENE® Primer B1 to all substrates and allow to dry. BITUTHENE® MRX should be laid by peeling back the protective silicone release paper and applying the self-adhesive face onto the prepared surface. The material should be brushed on to the surface to ensure good bond with 50 mm at side and ends, and the overlaps well rolled with a firm pressure to ensure complete adhesion and continuity. Following the application and inspection care should be taken to prevent damage by following trades. Any punctures or damaged areas should. be cleaned and p atched using BITUTHENE® MRX with a minimum 50 mm laps all round.
As soon as practicable after the application, the gas membrane system should be protected from physical damage. Protection is considered to be essential if the membrane is exposed to general site traffic and damage free integrity of the membrane cannot be guaranteed. Protection boards are available from GCP, see separate data sheet for details.
