Product Description

Steel-edge waterstop is a modification of traditional rubber waterstop with steel plate rings being inserted into the middle of vulcanized rubber. High liquid-tightness and high absorption of shear movements make the steel-edge waterstop a recommended choice for expansion, contraction joints and other construction fields with high pressure and structure variable.


Once the structure sedimentation, concrete shrinkage and creep occur, the rubber parts of steel-edge waterstops will be elongated and thin to adjust to these deformations without affecting the adhesion between steel plates and the rubber part, between steel plates and the surrounding concrete. In this way, the steel-edge waterstops are able to withstand greater tension and torsion than traditional waterstops; meanwhile, it effectively prevents concrete loosen, breaking off and the form of leaking cracks.


SEW-01: Steel edge waterstop with center edge.


SEW-02: Steel edge waterstop without center bulb.


Feature & benefits:

  • Quality EPDM rubber with high tensile strength.
  • Galvanized steel plate for high rust and corrosion resistance.
  • With punched holes on the steel plate for easy installation.
  • Adjustable to high movements and deformations.
  • High adhesion between the steel plates and the rubber.
  • Excellent fastness between the steel plates and surrounding concrete.
  • Custom types are welcomed.

SEW-03: Raw materials.


SEW-04: Production line.


SEW-05: Warehouse.


SEW-06: Package.
