The PROOFMATE® Waterstops are designed to be installed for sealing in construction and movement concrete joints. The application of waterstops is normally according to jobsite specifications, WU Guidelines or the DIN 18541 and DIN 18197. The sealing principle of in concrete embedded waterstops is the longer path of water circulation.
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 watestop profiles are made of high quality thermoplastic material (PVC-P) and are available in the regular production standards as well as according to DIN 18541 or, if requested, also in a bitumen resistant formulation. As for general jobsite regulation only „end-to-end“ joints are allowed, we can supply workshop finished pieces as “L”, “T”, cross or other special shaped welded elements. Additionally, under request, we are able also to deliver the bands together with VPRESS® injection hoses or HYDROSEAL swelling profiles. Special shapes and colors are also available under request.
