Construction membrane designed for use in applications where combined damp proofing and radon gas protection is required. Generally used within foundation constructions.
For use in applications where resistance to radon gas is required as part of either a ‘full’ or ‘basic’ radon protection system. It is generally used within construction applications, predominantly within the foundation design.
A high performance gas membrane which can also act as a high performance DPM.
