Waterstop for Environmental Engineered Concrete Structures — Waterstops for Chemical, Industrial, & Environmental Applications


Waterstop plays a critical role in the integrity of concrete structures. It provides a fluid-tight diaphragm when embedded in, and running through concrete joints. Earth Shield Thermoplastic Vulcanizate Waterstop (TPE / TPER / TPV), by J P Specialties greatly expands the scope of conventional waterstop by offering unmatched chemical resistance to a broad spectrum of aggressive chemicals, solvents, and hot petroleum oils. Manufactured NSF Certified, EPA-compliant (RCRA, SPCC, CFR 265.193, CFR 112) waterstop profiles are available for new construction and retrofit, as well as the necessary tools and accessories for proper installation.
