Installation Instructions
Securely install waterstops to hold them in place during concrete placement. Ensure concrete is fully compacted around them to eliminate voids or porous areas. Brass eyelets for securing the waterstops should be positioned outside the edge bulbs to prevent water from seeping around the profile.
Site Jointing Instructions
Jointing of Estopper CJ/EJ Range waterstop is carried out using Estop Heat Welding Equipment. The ends to be joined are cut square and held in alignment. The ends are then pressed to both side of a special heated blade, until an even, molten bead of PVC appears around the section.
Precaution
Hot welding PVC waterstops releases hydrogen chloride mist and vapor. Ensure ventilation is provided as the operational exposure limit (OEL) of 5 ppm can be exceeded in still, confined spaces.
