Earth Shield® Waterstop Solutions by J P Specialties: Advanced Protection for Concrete Structures

November 21, 2025

Waterstops play a vital role in safeguarding concrete structures by preventing fluid migration through construction and expansion joints. As a long-established manufacturer in this field, J P Specialties, Inc. delivers a comprehensive portfolio of Earth Shield® waterstop products engineered for demanding applications across chemical processing, water and wastewater treatment, fuel handling, and environmental containment.

For more than seven decades, the company has supplied engineering firms and project owners with high-performance materials supported by extensive technical expertise. Its product range includes thermoplastic vulcanizate (TPV) waterstops, PVC profiles, stainless-steel options, and hydrophilic rubber solutions, as well as specialized installation tools developed under U.S. Patent No. 4,867,835 for the thermo-welding of PVC, TPV, and HDPE waterstops.

Comprehensive Product Portfolio

TPV Waterstop: Earth Shield® TPV (TPE-R) waterstops offer exceptional chemical resistance, making them suitable for structures exposed to aggressive fluids, solvents, and hot petroleum oils. NSF 61 certification and EPA-compliant profiles support a wide range of new construction and retrofit conditions.
PVC Waterstop: Formulated from prime virgin resin, Earth Shield® PVC waterstops are frequently specified for water and wastewater infrastructure. These profiles comply with CRD C572-74 and are NSF 61 certified, providing reliable performance for environmentally engineered concrete systems.
Stainless Steel Waterstop: For projects requiring robust resistance to highly corrosive media or elevated temperatures, Earth Shield® stainless steel waterstops deliver long-term durability. Standard profiles are manufactured from 20-gauge 316 low-carbon stainless steel—well suited for ozone contactor structures and aggressive treatment environments.
MCR Waterstop: Earth Shield® Type NB190® hydrophilic chloroprene rubber waterstop expands significantly when exposed to water, doubling its original volume and maintaining its physical integrity through repeated cycles. Type NB190® is non-bentonite, heat-resistant, chemically resilient, and NSF 61 certified for potable water applications.

Commitment to Quality and Technical Leadership

J P Specialties has been recognized globally for its role in advancing waterstop technology. The company was the first manufacturer in the sector to secure NSF 61 certification, and its team contributes to industry standards through active leadership in multiple ACI committees. Its president, David R. Poole, authored The Little Book of Waterstop, a widely referenced guide among architects, engineers, and contractors.

Professional development remains a cornerstone of the organization’s mission. Thousands of industry professionals have participated in the company’s AIA-accredited seminar, available both in person and online, which provides one-hour CEU credits and comprehensive instruction on waterstop system design.

Support for Contractors and Project Teams

J P Specialties maintains robust inventories and competitive pricing to meet the needs of contractors working on critical infrastructure and industrial facilities. Factory-fabricated fittings are available for standard and custom configurations, helping streamline field installation.

In addition, the company offers specialized training programs through online and on-site waterstop welding schools. These programs provide certification in proper welding techniques and ensure that installers are equipped to deliver watertight, durable joints in the field.

“Water is our most valuable commodity. It is important to protect it, either from loss or pollution. Properly installed waterstop achieves both goals.”
— David R. Poole
