J P Specialties has been manufacturing the Earth Shield® line of waterstops for over 20 years. We are dedicated to providing technical support for a complete line of waterstops and focused on being the best. Our products (PVC, TPV, SS, and strip-applied) are specially formulated to have the best physical properties in the industry, and more importantly, we provide the best service and technical support.

At the engineering level, our technical leaders are officers in multiple ACI committees, we were the first waterstop company to get NSF 61 approval, and our owner has written the technical resource book used in the industry (Little Book of Waterstop by David Poole). Our popular accredited seminar (worth one hour CE credit) is presented nationally and internationally to over 200 engineering and owners offices with many thousands of attendees.

We also provide contractors with aggressive pricing, large inventories, and factory fabrications for both standard and custom fittings. J P Specialties also does on-site welding schools and certifies attendees for proper welding of waterstops.
