Bituthene® MRX

Specifically designed methane and radon gas resistant membrane, with a specially developed high strength composite backing film laminated to self-adhesive polymer compound, which provides dimensional stability, high tear strength, puncture and impact resistance.

Designed for use with Bituthene® MR DPC – a gas resistant damp proof course manufactured from polyethylene and aluminium film, and designed for use in cavity walls to maintain a continuous gas barrier across the wall cavity.

Substrate:

Monolithic concrete blinding is preferred which should be regular, smooth and free of loose aggregate and sharp protrusions.

Application:

Brush the membrane onto the surface to ensure good initial bond and exclude air.

Protection:

As soon as possible after 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.

Joint laps:

Minimum laps of 50 mm are recommended.
