Metal waterstop Fradiflex®

Waterstop for working joints

All concrete structures in contact with the ground must be sealed against ground moisture, seepage water or pressurized water. Our Fradiflex® metal waterstop system meets all requirements for the secure sealing of water-impermeable structures. The flexible special coating bonds with the concrete, creating an adhesive barrier seal that prevents water from circulating. The system can be used for the reliable sealing of construction and predetermined crack joints in in-situ concrete construction and with element walls.


  • More safety due to fewer splices (roll)
  • Simple position protection due to fixing angle
  • Tested up to 5.0 bar water pressure (according to ETA and abP 2.0 bar)
  • No welding necessary at the joints
  • Fast installation thanks to two fixing points (crack inducing elements)
  • Stable crack inducing elements (secure standing and position)
  • European Technical Assessment (ETA)
  • German National Approval
