Gas Barrier Products

MONARFLEX RAC Membrane is developed specifically for installation on contaminated ground to prevent gases from entering the structure. A well-protected aluminium foil serves as an efficient gas barrier and the reinforcement ensures that traffic on the membranes will not lead to puncture. The composition of the membrane with 6 independent layers makes it a perfect gas barrier for projects with rough conditions where the membrane will be exposed to heavy traffic from equipment during installation. Concrete can be poured directly into the membrane.

MONARFLEX RAC Membrane is a specially designed membrane with multiple layers of blown virgin polyethylene (LDPE) film, a reinforced polyester scrim and a 12 micron aluminium layer laminated together by several coater layers to a tough and durable gas membrane. The membrane consists of 6 layers in total ensuring a gas tight membrane with high mechanical properties. The special composition and properties of each layer of the product make a tight and effective barrier to prevent gas from entering houses and buildings to constitute and health hazard for the inhabitants.

MONARFLEX Reflex Super is a high performance, six layer membrane manufactured from virgin low density polyethylene (LDPE) with a polyester reinforcing grid and an aluminium foil layer to give high strength, tear resistance and low permeability to gas. The membrane is coloured sand on the upper surface with a silver coloured underside.

Reflex Super is part of the Monarflex gas control system and may be used loose laid with ground supported or suspended slabs and is suitable for use as a DPM when properly sealed and detailed to restrict the ingress of ground gases. Monarflex Reflex Super is recommended for use in situations of medium to high concentrations of radon gas or where methane, carbon
dioxide and other gases are present.
