SINTOFOIL ST WPS PT
Non-reinforced synthetic membrane for protection of underground TPO/FPA waterproofing systems.
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.
Fields of application
Specific use
The SINTOFOIL ST WPS PT membrane is suitable for the protection of waterproofing systems for underground works:
- foundations;
- retaining walls.
