Radon Membrane is a high performance gas membrane, for use in applications where resistance to radon gas is required as part of either a ‘full’ or ‘basic’ radon protection system. The membrane is generally used within construction applications, predominantly within the foundation design. It can also act as a high performance DPM.


  • Economical method of providing radon protection to newly constructed buildings
  • Provides additional damp proofing protection to the structure; no requirement for a separate DPM
  • Robust membrane with a high resistance to damage and puncturing
  • Complies with relevant industry codes and guidance including BR 211

Typically used to provide combined radon and damp proofing protection to newly constructed buildings and dwellings.

For ‘basic’ radon protection the use of the Radon Membrane covering the entire footprint of the building, used in conjunction with the relevant accessories and system components should be sufficient. However if there is the requirement to provide ‘full’ radon protection, the additional use of a radon sump (please see Radon Sump Data sheet) may be required.
