Waterstops for Chemical, Industrial, & Environmental Applications

Waterstop plays a critical role in the integrity of concrete structures. Waterstop provides a fluid-tight diaphragm when embedded in, and running through concrete joints. Earth Shield® Thermoplastic Vulcanizate Waterstop (TPV) (aka TPE-R), by J P Specialties dramatically 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 61 certified, EPA-compliant waterstop profiles are available for new construction and retrofit, as well as the necessary tools and accessories for proper installation.

Earth Shield® Polyvinyl Chloride Waterstop (PVC) is the perfect solution for most water and wastewater applications. Earth Shield® PVC Waterstop is manufactured from prime virgin resin and is the trusted choice for environmental engineered concrete structures. CRD C572-74 compliant and NSF 61 certified waterstop profiles for new and retrofit applications.

Earth Shield® Type NB190® Waterstop — a modern, hydrophilic chloroprene rubber waterstop with unmatched durability and water sealing capabilities. Manufactured NON-BENTONITE, modified chloroprene rubber, Type NB190® more than doubles its original size when exposed to water, creating an effective compression seal within concrete construction joints of limited to no movement.

J P Specialties, Inc. also manufactures a complete line of high-quality waterstop installation and welding irons, all of which are designed to save the contractor time and money.

Earth Shield® waterstops are used throughout the world by major engineering firms and project owners for primary and secondary containment, water and wastewater treatment, and ozone contactor structures. We invented the technology used to mechanically weld thermoplastic waterstops. Services offered include shop drawings, on-site and on-line waterstop welding certification, and individual corrosion resistance certification for the project owner.
