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.
