Earth Shield® Waterstops for Chemical, Industrial, & Environmental Applications

SINCE 1954, J P SPECIALTIES HAS BEEN THE GLOBAL LEADER IN MANUFACTURING THE EARTH SHIELD® LINE OF WATERSTOPS, RENOWNED FOR THEIR SUPERIOR QUALITY AND PERFORMANCE. WE PROVIDE A WIDE ARRAY OF WATERSTOPS AND ACCESSORIES, ALL SUPPORTED BY EXCEPTIONAL TECHNICAL EXPERTISE AND CUSTOMER SERVICE.

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.

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 environmentally engineered concrete structures. CRD C572-74 compliant and NSF 61 certified waterstop profiles for new construction and retrofit applications.

Earth Shield® Stainless Steel Waterstop can stop even the most corrosive fluids in their tracks, even at severely elevated temperatures. A variety of metals, grades, and gauges are available. Earth Shield® utilizes 20 gauge 316 low carbon as our standard alloy, which offers broad-spectrum corrosion resistance to most aggressive media, and is virtually untouched by the deleterious effects of ozone, making it an ideal choice for ozone contactor structures used in modern water treatment plants.

Earth Shield® Type NB190® is 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 (400% in 36 days) when exposed to water. Type NB190® can expand and re-expand unlimited times with virtually no loss of physical properties. Additionally, Type NB190® has excellent resistance to many chemicals, is heat-resistant, and is NSF 61-certified safe for drinking water.

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 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).

Our technical team includes leaders who serve as officers on multiple ACI committees, demonstrating our commitment to excellence in engineering. We are proud to be the first waterstop manufacturer to achieve NSF 61 certification, setting the standard for quality and safety in the industry. Additionally, our owner, David Poole, authored
The Little Book of Waterstop, the definitive guide widely used by professionals in the construction sector.

J P Specialties is dedicated to advancing industry knowledge through our popular AIA-accredited seminar. This seminar, available nationally, internationally, and online, provides one-hour CEU credits and has been attended by thousands of architects, engineers, contractors, and owners. We are committed to supporting contractors with competitive pricing, extensive inventories, and customized factory fabrications for both standard and custom waterstop fittings. Our comprehensive training programs include on-site and online waterstop welding schools, where attendees are certified in proper waterstop welding techniques.
