A page dedicated to all things waterstop, as used to seal joints in concrete construction. Feel free to post any comments or questions and I will answer promptly. Also visit www.jpspecialties.com to view my company and its waterstop products.
It is recommended to verify temperature using an external thermometer.
NOTE: The Peel and Stick Teflon® Cover is to remain on the iron during the welding process. DO NOT REMOVE.
CAUTION: Too high of a temperature will result in damage to waterstop welds, splicing iron cover, and possibly splicing iron.
1. Always cut square ends before welding waterstops. Never weld to extruded ends. Use flat work table to create field splices. Work area should be solid and have access to power supply and have jigs and fixtures to aid splicing.
2. Cut ends square, using a razor knife or circular saw equipped with a carbide tipped blade (10” diameters with 40 teeth) to ensure matching edges.
3. Preheat the iron to the desired temperature ranges. Place iron between butt ends. Keep waterstops in place until approximately 3/16” bead forms on each side of waterstops. Quickly remove splicing iron and gently press waterstops ends together until they bond (approximately 3 to 5 minutes or cool to touch). Cold water may be sprayed on waterstops to expedite the bond.
