Keycup™ is a multi-function, reusable concrete accessory that securely holds waterstop in place while simultaneously creating a keyed construction joint. Typical applications include:
- Slab on grade
- Wall joints
- Lumber replacement
- Labor saver
MSB Form is an adjustable formwork solution for the concrete construction industry, designed to be compact, lightweight, and strong for all conditions and applications - commercial, industrial, residential, and civil.
When used in conjunction with one another, Keycup and MSB Form are the ultimate labor-saver for keyed concrete slab joints.

|The ST-10® Waterstop Splicing Table by J P Specialties, Inc.|
The ST-10® was designed and patented by J P Specialties as the perfect solution for producing high-tensile strength, leakproof welds on thermoplastic waterstops such as PVC, HDPE, LDPE, TPER, and TPV. New quality assurance standards in today’s waterstop specifications mandate tensile testing across field welded joints, usually requiring tensile strength 80% or better of the parent material. Waterstops welded with the ST-10® assure the Contractor that their workmanship will yield results conducive to these rigorous requirements. The ST-10® is also an extreme labor saver, taking a two-man job — welding waterstop — and taking it down to just one man.

Integrated expansion board cap waterstop systems are designed to replace post-applied joint sealant, and provide a fluid-tight internal seal like a traditional waterstop with a one-step, integrated unit. Install Earth Shield® expansion board cap waterstop on top of conventional expansion board filler or Earth Shield’s chemical resistant, plastic expansion board. The expansion board acts as the form; therefore, no form splitting is necessary, significantly accelerating the project schedule and provides a long-lasting, attractive finished concrete joint. Earth Shield® screed key cap slides over the top of the metal screed key, eliminating the need for sealant. Like all our thermoplastic vulcanizate waterstops, Earth Shield® integrated cap system waterstop can be heat-welded using a standard waterstop splicing iron allowing for easy field fabrications and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop directional changes are available along with straight roll stock. Custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.
