JP Specialties
JP Specialties has been manufacturing the Earth Shield® line of waterstops for over 20 years. We are dedicated to providing technical support for a complete range of waterstops and focused on being the best. Our products (PVC, TPV, SS, and strip-applied waterstops) have the best physical properties in the industry, and more importantly, we provide unmatched 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 leading professional resource book used in the construction 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 owner offices with many thousands of attendees.
We also provide contractors with aggressive pricing, extensive inventories, and factory fabrications for both standard and custom fittings. JP Specialties also does on-site welding schools and certifies attendees for the proper welding of waterstops.
