Gas Barriers

Viking Containment has extensive experience in the supply and installation of liner systems for building foundations, cut-off walls and gas barrier systems.

Geomembrane selection is dependent on the substance to be contained; we can provide chemical compatibility and vapour permeability testing to determine the appropriate material for a specific project. Penetrations, perimeter sealing methods and liner protection during and post installation should also be considered to ensure the integrity of the gas barrier is not breached.

A gas management system should include a gas vent or extraction system beneath the geomembrane liner to remove accumulated gas. We recommend using a Consultant Engineer for the system design.

Gas Barrier Liners Will Provide Protection From:

  • Methane gas
  • Hydrogen Sulphide
  • Hydrocarbon vapour
  • Moisture vapour
  • Water ingress


  • Foundation liners
  • Gas barriers
  • Cut-off trenches
  • EPS foam encapsulation
  • Waterproofing
