Ozone Resistant TPV Waterstops

Modern water treatment facilities, particularly ozone contactor structures, have utilized Earth Shield® waterstop for over 20 years. Earth Shield® thermoplastic vulcanizate (TPV) waterstop is immune to the corrosive effects of concentrated ozone. Our TPV polymer waterstop is suitable for ozone exposures up to 600 pphm (parts per hundred million). 

Independent ozone resistance testing (ASTM D 1171) has been performed on our product under direct contact, side-stream, off-gas, and finished water conditions. There was only a slight deviation from the control sample and negligible loss of physical properties.

JP Specialties, Inc. has been in the waterstop business since 1954. We offer a complete system — CAD drawings, shop-made fittings, waterstop welding equipment, and more.

Lead-free and NSF 372 Certified Waterstops

Lead is a metal used in the plumbing and waterworks industry. Lead can dissolve into the water supply from drinking water system components it contacts (pipes, fittings, waterstopset al.). The maximum lead content in drinking water system components is 0.25%, as defined by the NSF 372 Standard.

Earth Shield® polyvinyl chloride waterstops are certified to NSF/ANSI 372 and conforms with the lead content requirements for the U.S. Safe Drinking Water Act.
