R. W. Sidley, Inc. was established in 1933 as a mining and manufacturing company. Since then we have continued to build our company through the development of high quality products derived from our original core products of silica sand and bank gravel. As a full service supplier R. W. Sidley, Inc. provides a broad range of construction solutions for today’s building industry. We manufacture and supply bulk aggregates, industrial minerals, ready mix concrete, masonry block products, Pro/Angle bunker sand, structural and architectural precast components and building supplies. In 1962, the company expanded into the precast concrete industry and since that time has produced and erected precast and pre-stressed concrete products. Currently the Thompson plant focuses on architectural precast components. In 1995, a second production facility was acquired in Youngwood, PA. At this plant we are presently manufacturing structural precast components and hollowcore. Then in 2001, Carr Concrete Corporation in Waverly, WV was acquired, at this facility many different types of specialty precast products are produced including: bridge beams, burial vaults, concrete buildings and structural precast components. A dock along the Ohio River was built to allow shipment via barge of larger projects. Manufacturing operations are carried out in all three plant locations, enabling us to meet critical schedules by utilizing all three plants to manufacture precast components as dictated by the job schedule.
