SINTOFOIL ST WPS
Non-reinforced TPO/FPA synthetic membrane for underground waterproofing.
Synthetic waterproofing membrane produced by co-extruding a uniform highly flexible elastomerised polyolefin alloy. The membrane features contrasting colours on its upper and lower faces, providing a signal layer so that any damage occurring during or after installation will be immediately apparent. It is not UV resistant. SINTOFOIL ST WPS membranes comply with CE marking requirements, if applicable.
Fields of application
Specific use
SINTOFOIL ST WPS membrane is recommended for waterproofing of underground structures:
- foundations;
- retaining walls;
- natural and artificial tunnels.
