Contaminated site gas vapour barriers

Contaminated site remediation

With today’s technology we are able to build on contaminated sites which would not of been possible previously without major earthworks.  Gasses can be caught rising from the ground and vented above the roof line so they do not enter a habitable space.

The main gas we deal with is methane – a contaminant from old rubbish dumps, foundry’s. However our certified and engineered remediation system can by used on sites for a large range of contaminants.

When completed a quality assurance process is undertaken by pumping the membrane off the ground with smoke and air to test for any leaks.  It is then fully certified and a further protective layer is put over the membrane to protect it from the concrete pouring process.
