Waterstop Fittings

Why the Engineer Should Specify Shop Made Fittings

Shop Made Fittings are recognized and specified worldwide by major engineering firms. The U.S. Army Corps of Engineers also specified Shop Made Fittings in the July 1995 revision of CEGS Section 03250. Shop Made Fittings are specified because they work. Edge-welding waterstop severely compromises the integrity of any project. Even the limited movement of concrete during the coefficient of expansion and contraction can be too much for edge welded waterstop. The edge welded waterstop lacks the proper tensile strength and does not maintain the characteristics of the parent material (bulb or rib continuity). Consequently, the waterstop often tears at the most critical junction: the change of direction. Since all waterstops are designed to act as a continuous, fluid-tight diaphragm which fluids (generally water) traverse, the structure that uses edge welded waterstop will naturally leak, as fluids migrate to any tears in the weld and pass through to the other side of the joint.

Structures that use Shop Made Fittings will significantly reduce these waterstop failures. The tensile strength of the weld will be at least 80% of the parent material, maintaining the continuity of the bulbs and ribs across the weld. In other words, the waterstop will perform as intended and last the life of the structure.

CAD Drawings

J P Specialties has an extensive library of CAD drawings that illustrate the many uses of various Shop Made Fittings and explain waterstop's role in creating a fluid-tight structure.

Why the Contractor Should Use Shop Made Fittings

J P Specialties certified welding crew efficiently manufactures large quantities of top-quality Shop Made Fittings with speed on our exclusive XLT-2000 Waterstop Splicing Tables. Therefore, we can pass the savings on to the end user: the contractor. Besides saving money, the contractor who uses Shop Made Fittings will save time. A standard flat cross has twelve cuts and seven welds. By using Shop Made Fittings, all of the cuts and three of the welds are eliminated. The number of welds is further reduced by using modules.

What are Shop Made Fitting Modules?

Modules are custom Shop Made Fittings that deliver to the job site as a complete unit, rather than a collection of parts. For example, a box culvert with a longitudinal joint would typically require four vertical ells and two flat crosses. Even with Shop Made Fittings, this would be sixteen butt welds (straight edge to straight edge) for the contractor in the field. With proper dimensions from building plans, J P Specialties will manufacture entire box culvert modules. In the box culvert example conveyed above, using modules, only four butt welds remain to be done in the field.

Modules work best when the engineer specifies them during the design phase of the project, but they can also be used effectively during the construction phase with close collaboration between J P Specialties and the contractor. J P Specialties can interpret project plans during any stage of construction and render how Shop Made Fittings or modules will improve the quality of your structure and save you money.

How Much Do Shop Made Fittings Cost?

Shop Made Fittings can be supplied at a cost saving to the contractor on most jobs when compared to the time and labor necessary to fabricate the Waterstop in the field. Providing Shop Made Fittings will not only be more cost effective but will ensure a timely installation, thus saving costly delays. Also, our Shop Made Fittings will enhance your ability to meet stringent hydraulic tests required by engineers.

Waterstop eBook
Concrete is everywhere: Buildings, fountains, parking decks, locks and dams, roads and bridges, and myriad other constructions. Because of its long lifespan, high workability, and near-worldwide availability, concrete is the preferred building material for large structures, especially those subject to hydraulic pressure. Not all concrete structures require protection from the ingress of water or other fluids, but those that do require a properly installed waterstop in and along their concrete joints. The concrete joint is the most likely point of leakage and waterstops are uniquely designed to prevent this. This book’s sole purpose is to educate the reader on all facets of waterstop.
