CONTENTS CONCRETE REPAIR CORROSION CONTROL GROUTS & ANCHORS PROTECTIVE COATINGS INDUSTRIAL FLOORING SURFACE TREATMENTS JOINT SEALANTS CONCRETE JOINTING ROOFING WATERSTOPS WATERPROOFING JOINT FILLERS TIMBER FLOORING ALPHABETICAL Sure-Stop PVC Waterstops Site Joining On-site joining is a simple exercise using Sure-Stop heat welding equipment comprising of an adjustable welding jig and heating blade. The ends of the waterstop are cut square and placed into the adjustable jig. The ends of the waterstop then slide up against the heating blade until a bead of molten PVC appears along the length of the blade. Remove the heating blade and bring the two ends together until the molten ends of the PVC fuse. When ordering welding equipment, please advise style and width of waterstop required. Full instructions are available from Parchem or your local distributor. Welding Equipment Welding blades and separate welding jigs for Centrestop and Rearguard profiles are available for hire.
