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 and welding irons, saving the contractor time and money. We invented the tools and technology used to mechanically weld thermoplastic waterstops.

SS Waterstop — 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.

MCR Waterstop — 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. This expansion creates an effective compression seal within joints of limited to no movement. Type NB190® can expand and reexpand unlimited times with virtually no loss of physical properties. Additionally, Type NB190® has excellent resistance to many chemicals, is heat-resistant, and is safe for drinking water.
