PROOFMATE Waterstops

According to this physical principle, differently to other forms of joint sealing like swelling profiles or injection hoses, there is the placement of a physical barrier that requires from the incoming water to follow a path along and around the rippled structure that is longer than the actual permeability of the concrete.

  • The standard special part length is 0,50 m (measured ont he axis), other lengths possible under request.
  • Specific taylor-made shapes can be designed and executed under request.
  • Combined welded special parts are possible under request.
  • It is recommended to limit the special pieces to a maximum of 25m length due to dimensional reasons. Longer elements are not guaranteed to maintain their dimensional precision. Special welded elements and systems are custom made and after completion cannot be taken back.

* BV-quality (bitumen compatible) waterstops in most cases have different (higher) elongation at break. This type is not standard, only available under request. The single pictures of the waterstops are indicative of the listed profiles and serve only as illustrative examples. The correct application depends on the local conditions, therefore no guarantee can be given. All data and specifications are based on the present state of the art and the right to changes and adaptations for the sake of development remains explicitly reserved.
