Waterstop has a singular purpose: To prevent the passage of fluids across and along concrete joints. This page is 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.
Earth Shield® part no. JP216L Retrofit Waterstop is designed to provide a fluid-tight seal between existing and new concrete construction, without resorting to the labor-intensive and structurally destructive saw-cut-and-grout method. It is ideal for joining a new slab to an existing wall. Special profile fabrications are available for columns and pipe penetrations. All of our retrofit waterstops are sold as a complete system, and include all the necessary stainless steel bars and bolts. We also offer a high-quality chemical resistant novolac epoxy — VEN 1000. Earth Shield® retrofit waterstops are manufactured with our proprietary thermoplastic vulcanizate compound, which provides for unsurpassed chemical

resistance. Like all our thermoplastic vulcanizate waterstops, Earth Shield® retrofit waterstop 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.
