It all started when...

In 1978, Wm. (Bill) Dawson and Charlie Busch opened a new quarry site on State Highway 47, midway between Union and Washington, Missouri. Their plan was to serve the central part of Franklin County, focusing on Washington and Union as the largest growth area between St. Louis County and Jefferson City. Wm. Dawson eventually acquired full interest in the quarry and successfully operated it until his retirement in 2014. Riverstone Quarry acquired all assets and properties of the business from Mr. Dawson and currently operates under the name “Riverstone Quarry – Union Plant”. Since the 2014 acquisition, much of the plant and plant support equipment has been updated to assure the reliable and consistent operation our customers have come to expect. The Union site consists of approximately 200 acres with many years of reserves available.
