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

June 05, 2023

Since 1954, J P Specialties, Inc. has been manufacturing the Earth Shield® line of waterstops. We provide technical support for a complete range of waterstops and waterstop accessories. Our waterstop products (PVC, TPV, stainless steel, and strip-applied) have the industry's best physical properties; more importantly, we provide unmatched service and technical support.

Our technical leaders are officers in multiple ACI committees at the engineering level. We were the first waterstop company to get NSF 61 certification. Our owner has written the leading professional resource book used in the construction industry (The Little Book of Waterstop by David Poole). Our popular AIA-accredited seminar (worth one-hour CEU credit) was presented nationally, internationally, and online to engineering and owner offices with thousands of attendees.

We also provide contractors with aggressive pricing, extensive inventories, and factory fabrications for standard and custom waterstop fittings. J P Specialties also offers on-site and online waterstop welding schools and certifies attendees for properly welding waterstops.
