Our History

K.J. Williams Concrete Co. Inc. is a family owned business that has been manufacturing precast concrete solutions for consumers since 1958. The staff at our facility has over 100 years of combined experience in the precast concrete industry: providing an edge that competitors can not match. We are committed to producing the highest quality precast concrete products on the market and providing world class customer service. In 1974, the focus of the company switched from manufacturing precast concrete products for the public, to manufacturing precast solutions for the Department of Transportation (DOT) and their subcontractors. The focus of the company is to create quality precast MSE panels, lagging panels, noise barriers and coping for the Department of Transportation. Precast concrete products manufactured at our Cresaptown, MD facility can be seen in Maryland, Pennsylvania, Virginia, Delaware, and New Jersey.
