PROJECT BACKGROUND

Bellisio Foods is a major frozen food manufacturer whose brands include Boston Market, Michelina’s, and Atkins Frozen. In 2018, the manufacturer needed to rehabilitate its 170-foot diameter concrete anaerobic digester tank at their Ohio facility. It was showing signs of severe deterioration on the walls above the waterline.  

​

Warren Environmental’s (Warren) epoxy coating system was a quick and effective rehabilitation method that added valuable service life to Bellisio Foods’ anaerobic digester tank with minimal impact on their operations. 

​

A&W Coatings used Warren’s 301-14 epoxy to repair the tank’s concrete surfaces. Before coating the walls, the team abrasive blasted and water blasted the substrates to remove loose concrete. Afterward, A&W spray-applied 375 to 500 mils of Warren’s 301-14 epoxy to the concrete surfaces. Areas with exposed rebar required repair with Warren’s epoxy mastic before being coated. Repairs from within the tank required two flotation rafts. All of our technicians wore harnesses and were tied off to the safety line established around the outer circumference of the tank to perform the work safely.
