Metal water stop for in-situ concrete Fradiflex®

Water stop in concrete working joints

All concrete structures for high-grade use must be sealed against soil moisture and pressing water (white tank).

The Fradiflex® metal water stop for fresh concrete meets the requirements of the guideline for watertight structures and provides a safe and economical joint seal.

The barrier and adhesion seal with special coating forms a particularly strong bond with the fresh concrete and thus prevents water circulation (water penetration).

MAX FRANK produces the Fradiflex® metal water stop system for reinforced concrete construction in various designs for in-situ concrete and precast element construction.


  • Galvanized steel sheet with bitumen-free special coating guarantees sustainable sealing
  • Metal water stop with CE mark
  • Tested to 50 m head of water
  • Density self-adhesion of butt-joints, no welding necessary
  • Joint seal of all working joints without concrete upstand
  • Reduced assembly times thanks to integrated fixing angles
  • Fradiflex® on a roll saves time and guarantees safety
