Application Instructions
Heat Jointing Equipment (220 V)
Heat welding equipment is available from Estop Sdn Bhd. Ensure the heat welding equipments are earthed by the green wire.
Installation Instructions
Waterstops must be installed so that they are securely held in their position while the concrete is being placed. Concrete must be fully compacted around the waterstops to ensure that no voids or porous area remain.
The brass eyelets used for securing the waterstops are located outside the edge bulbs so as not to create water paths 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. .
The heated blade is then removed and the molten ends pressed fully together. The PVC cools to form a strong fusion welded joint
An experienced technician would perform the jointing of the waterstops to satisfaction, subject to prior training and approval by Estop Technical Department.
