Sika Waterbar® FB-125

Bonded flexible waterstop for sealing construction joints

Sika Waterbar® FB-125 is a hybrid waterstop with a rough textured surface based on flexible polyolefin (FPO). The waterstop is placed into the fresh concrete and becomes fully embedded in the cured concrete. It provides a fully bonded, durable watertight seal, that prevents any lateral water underflow.

  • Bonded to concrete structure - no lateral water underflow
  • Permanent flexibility
  • Quick and easy to install
  • Long rolls reduce the number of joins
  • No special tools and equipment required
  • No extra recess and detailing of reinforcement
  • No obstructions for concreting
  • Fully bonded for easy repair in case of leakage
  • Resistant to all natural substances in soil and groundwater
  • Durable and robust system
  • Can be combined with other proven Sika waterproofing / joint sealing systems
