SikaProof®-110 FB8

2.0 mm thick FPO membrane with a hybrid bonding layer for waterproof tunnel lining

SikaProof®-110 FB8 consists of a flexible polyolefin (FPO) layer membrane (EVA based) with a hybrid bonding layer that forms a mechanical and chemical dual bond with the in-situ concrete lining, and a non-woven polypropylene geotextile (felt), which is linearly fixed onto the membrane and serves as protection.

  • Also available without geotextile (felt)
  • High mechanical and chemical bonding properties on the inner concrete lining
  • No lateral water migration between concrete and membrane
  • Very good thermal jointing properties
  • Flexible in cold temperatures
  • High crack-bridging ability
  • Simple and fast to install
