About us

Our History

In 1957, American Concrete Industries (then Maine Shawnee Step Company, Inc.) purchased land from Superior Concrete. Snowe Brothers: Carlton, Richard and John next door to Superior Concrete. After 10 years, in 1967, the company expanded into the Bangor area and changed its name to American Concrete Industries, expanding our precast line to residential septic systems, commercial wastewater & storm-water management, and other various precast concrete items.

In 2014, we acquired assets from our neighbor Oldcastle (Auburn) [formerly Superior Concrete] and reopened with the Superior Concrete name.
