Earth Shield® 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® waterstops are used worldwide by major engineering firms and project owners for chemical containment, water and wastewater treatment, fuel resistance, and ozone contactor structures. J P Specialties, Inc. also manufactures a complete line of high-quality waterstop installation tools and accessories. We invented the tools and technology to thermo-weld plastic (PVC, TPV, HDPE) waterstops (U.S. Patent Number 4,867,835).

Earth Shield® waterstops are designed to meet strict performance requirements and regulations, which helps ensure critical structures remain fluid-tight and stable throughout their lifespan. By choosing the appropriate waterstop design and installation methods, engineers can effectively handle the challenges related to concrete joint sealing and contribute to the long-term success of their projects.
