LOGICBASE P-SL

Non-reinforced TPO/FPA synthetic membrane for underground waterproofing

USEFUL

Synthetic waterproofing membrane produced by co-extruding a uniform highly flexible elastomeric 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. LOGICBASE P-SL membranes comply with CE marking requirements, if applicable.

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

Fields of application

Specific use

  • LOGICBASE P-SL membrane is designed for waterproofing of underground structures: foundations, retaining walls, natural and artificial tunnels.
