Introducing Concrete Controls Corporation, Moisture, Slump, and Temperature specialists since 1956. Concrete Controls Corporation was founded by Paul M. MacKinney, who has now retired to sunny Arizona. In 1956 Paul M. MacKinney introduced slump controls to the industry. Over the years many more process controls have been developed and shown from his unique motorhome showroom.

In 1988 ownership of the corporation was passed to his son, Paul E. MacKinney, who has a degree in Electrical Engineering Technology from LeTourneau University and 25 years of concrete plant experience alongside his father.
