Gas barrier membranes
A range of gas barriers is available, and PAG will be pleased to recommend the appropriate specification. The system provides passive protection without the need for monitoring or mechanical equipment and so is ideal for housing and small industrial units. For large installations or those requiring additional protection, please ask for details of PAGeotechnical active and supported systems.
PAG has developed a range of high quality products to provide both barrier and venting. Gas barrier can be supplied in preformed sections - especially useful to speed up installation on housing sites. Alternatively joining can be carried out on site.

Spray applied membrane
LIQUID BOOT® Membrane is a cold, spray-applied membrane that provides an impermeable barrier against gas and vapour intrusion into structures. LIQUID BOOT® is sprayed directly to penetrations, footings, grade beams, pile caps, etc., providing a fully-adhered and seamless membrane.
- Excellent sealing of penetrations.
- Seamless, monolithic membrane; no additional sealing required.
- Functions well in larger industrial applications as well as smaller residential applications.
- Ideal for complicated sub-structures and vertical applications.
- Rapid and simplified installation minimises construction time.
