LOGICBASE P-PT

Non-reinforced synthetic membrane for protection of underground TPO/FPA waterproofing systems

USEFUL

TPO/FPA Synthetic membrane produced by co-extruding a uniform highly flexible elastomerised polyolefin alloy. It is not UV resistant. It is recommended as a protective layer of synthetic waterproofing systems in TPO/FPA for underground works.

Notes: (1) The membrane is equipped with specific accessories, to be requested explicitly.

Fields of application

  • The LOGICBASE P-PT membrane is suitable for the protection of waterproofing systems for underground works: tunnels, foundations, and retaining walls.
