Dalmaray was founded in 1957 by Dale Carr, Marie Carr, and Ray Hemmingway. It started with no shop, minimal forms, and one block and tackle truck. But in just 50 years time, Dalmaray has grown to become one of the largest precast producers in Wisconsin.

By adding Helix® Micro Rebar™ steel reinforcement as a structural reinforcement technology, Dalmaray is able to create a stronger, three dimension reinforced manholes, and reduce hours from the overall manufacturing time.
