http://www.jpspecialties.com/Waterstop_for_Concrete_Joints/specialshapes.html Earth Shield tear web waterstops are designed for large joint movements such as tank foundations. Tear web is suitable for expansion joints. For construction and contraction (control) joints, ribbed centerbulb should be used instead. We also manufacture a retrofit product specifically designed to accommodate large shear movements, such as tank ring foundations subjected to settlement. The JP621L Retrofit Waterstop System is chemically and mechanically adhered to the existing concrete using one of our chemical resistant, novolac epoxies (VEN500 or VEN1000), stainless steel batten bar, and stainless steel anchor bolts. Like all our thermoplastic vulcanizate waterstops, Earth Shield tear web and large movement retrofit waterstops can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.
