The Findlay Water Infrastructure Improvements project, completed on October 1, 2024, focused on rehabilitating vital water infrastructure in Findlay, Ohio. The City of Findlay, working with Arcadis as the engineer and Culy Contracting LLC as the field applicator, sought an effective solution to restore their aging water infrastructure. The project involved the application of Series 456 CPP Sprayliner to a pipe substrate, including concrete precast and ductile iron components, which required specialized care and attention throughout the process.

The rehabilitation process was streamlined with the use of spin casting for the application of Series 456, utilizing a 1/2″ double hose with 350-foot pulls to coat all substrate surfaces at 250 mils DFT in a single pass. Prior to application, meticulous surface preparation was carried out, including the use of a vac/jet truck, manual pressure washing, mechanical grinding on ductile iron, and mechanical descaling with a jet truck. The project was further complicated by the challenge of keeping the product at the proper temperature during application and preventing the umbilical cord from bunching up during spin cast. Despite these challenges, the team achieved efficiency, completing the spin-cast application in just two days after the initial prep work had been finished the week before.
