Gas Barrier Membranes

Methane and Carbon Dioxide Barrier Membranes

For lower gassing commercial sites and amber 1 housing land we install a robust and flexible HDPE membrane of high quality and resistance to puncture, which is suitable as a damp proof membrane.

For higher gassing sites and amber 2 classified housing land we install an aluminium foil laminate membrane with a higher resistance to gas transmission. The installation is then gas integrity tested and certified as representing the required gas barrier click here.

Radon Barrier Membranes

For radon protection we install a strong and durable multilayer HDPE membrane with a pressure balancing manifold below click here. The installation is then gas integrity tested and certified as representing the required gas barrier click here.
