About Project

In February 2022, Thomas Industrial Coatings started a six-week project to renovate two settling basins (20,760 square feet) in the water treatment facility. The scope of work called for SSPC HP WC high-pressure water cleaning, muriatic acid cleaning, and SSPC SP 7 brush blasting of the floors.

A 3,500-square-foot flocculation (waste mixer) was also part of the renovation project, with the same surface preparation performed. Additionally, one of the basins required the exact scope of work to extend two feet past the basin wall. This basin also required approximately 800 square feet of concrete repairs and crucial joint saw cutting to terminate the liner consistently. To complete the scope, the scrubbers in the basins were removed with a crane before production.

The liner system applied was an Induron Perma-Clean 100 Ceramic Epoxy. The coating was used with a plural component system with two applications of 50 mils dry film thickness each in all project areas. SITKA ARMATEC 110 Epocem for coating the exposed rebar during concrete repair. SITKA SHB was used on the spalled areas of concrete.

After application, the basins were disinfected per AWWA C65-13, and the 100 percent solids epoxy was high-voltage holiday tested.
