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, dumping trucks, and roll-off trucks that service a large selection of trash and debris containers.

It is with much sadness that we announce the passing of one of Maryland Portable Concrete’s original founders, Winfield Marshall (Marty) Hamilton. Marty was instrumental in literally building Maryland Portable from the bare ground up! He knew every employee on a personal level and typically worked side by side with them daily. Anybody that was new to the company thought Marty was one of the employees, rather than an owner – showing up to work every day in an old pair of overalls and an Oldsmobile sedan with the trunk crammed full of tools. His engineering mind and mechanical talents were matched only by his fun-loving nature and willingness to make people laugh. One of our long tenured employees remarked that you could spend all day working hard with Marty and not even feel like you worked because he made it enjoyable. He will be sadly missed and fondly remembered by all those who had the opportunity to meet and work with such a uniquely skilled and warm-hearted person.
