Gas barriers - venting for new buildings

With the increase in development of brown field sites the prevention of ingress of
noxious gases into buildings is increasingly becoming an issue.

When installed before the laying of floor slabs or concrete screeds, WTB
Geotechnics’ Excelastic gas barrier membranes provide a continuous high integrity barrier to prevent methane and carbon dioxide gas ingress into buildings.
