We are a concrete block manufacturing facility established in 1920, located in Central Massachusetts. We have been family owned and operated for 4 generations. We manufacturer Architectural finished CMU, Pave Drain Storm Water CMU, Hi-R Insulated CMU, Keystone Retaining walls, and Grey Block. Traditional values practiced out of necessity have evolved into present day resource conservation. We continue to improve the efficiency of our manufacturing process, while simultaneously lessening our impact on the environment.
