Centrifugally Cast Concrete Pipe (CCCP) rehabilitation was performed on this failing 84″ storm drain in Lihue, Kaua’i. The storm water pipe was rehabilitated without digging, the method allowed the pipe to retain much of its original design capacity, and all while allowing the storm drain to operate normally during rain events. National Plant Services was contracted to perform specialty work on the project, including injection grouting and structural mortar lining.
