Maryland Portable Concrete, Inc. is the only remaining family owned and operated ready-mixed concrete producer in the Maryland, Delaware, Pennsylvania tri-state area. Through hard work, honest business practices, and personal customer contact that only a family owned business can provide, the company has grown tremendously over the past 37 years. Today, MPC operates two plants in Harford County, and two in Cecil County. Our delivery fleet of over 140 vehicles is comprised of front and rear discharge ready-mixed trucks, concrete pumping trucks, dump trucks, and a newly expanding fleet of roll-off container trucks.
