PASSIVE gas protection for industry

PAGeotechnical's passive protection system comprises a gas barrier membrane, in combination with a ventilation system to remove gas.

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.
