JP Specialties, Inc. has solved a long-standing problem for engineered concrete structures with small diameter, circular protrusions, such as columns and pipes. The problem: how to permanently seal the concrete joint when cast-in-place concrete is formed against the existing circular member. The solution: CAPwrap (part no. CW2110) manufactured with a flexible, soft durometer, chemical-resistant polymer and stainless steel anchoring hardware. A single laborer on the job site can quickly install the polymer ring and its associated hardware. Simply apply an epoxy gel bed to the existing surface; place the polymer ring into the epoxy gel bed; heat weld the single opening on the polymer ring using a waterstop splicing iron; and finally, complete the system with the stainless steel closure ring.

The CAPwrap system functions as an internal dam, centrally located within the cast concrete, to stop water, aggressive chemicals, solvents and hot petroleum oils from penetrating the joint. By preventing the passage of hazardous liquids the CAPwrap system provides facility owners, engineers, and contractors with the necessary EPA-mandated containment compliance (EPA Title 40 CFR 265.193). Of course, the system prevents the passage of water as well.

CAPwrap is easy to install and economical. Contact JP Specialties, Inc. to learn more.
