DELTA® Gas Barrier System - Gas barrier and damp-proofing

A high performance polymeric radon, CO2, and damp proof membrane.


  • Offers protection not only from the radiation of radon but also CO2, and when used with Delta® gas resistant dpc and preformed units the system offers a completely sealed solution to penetration of gases and ingress of dampness from below ground and through cavity walls.

Technical data:

  • Formed with anti-slip profile on both sides, which stabilizes the sheet and optimizes adhesion to mortar.
  • Compatible with bitumen, resistant to degradation and UV-stabilized.
  • Tightly sealed with products from the Delta® range of adhesives, the membrane becomes a barrier that is highly effective on overlaps and seams.
  • Will not crack even at low temperatures, and being flexible it will easily bend around corners.
  • Conforms to BR 211, BR 212 and Building Regulation Document C.
