MORE ABOUT US   Keystone Concrete was established in 1962 when Herb Hatfield purchased a concrete plant in downtown Churubusco. He began supplying concrete to local builders and farmers and eventually brought his sons into the business. Herb passed away some twenty plus years ago leaving Keystone in the hands of his wife and sons. When Keystone outgrew its location, a new plant was constructed in Allen County just north of Carroll road. As the company continued to grow, numerous trucks and two more concrete plants where added. Today, the majority of concrete that Keystone batches comes from our state-of-the-art Central Mix plant. The Central Mix thoroughly mixes the concrete before it is loaded into the trucks giving the most consistent mixes possible. Other technologies Keystone Concrete has adopted include an eight million BTU water heating system, heated aggregate bins, auto/data control and truck tracking just to name a few.  When it comes to quality controls, Keystone has gone above and beyond the industry standard. Not only are all aggregates and cements hauled by full time Keystone drivers, but all the sand comes from our own aggregate facility. This assures customers that only the best and most consistent materials make it into the concrete mixes.   Keystone Concrete has provided concrete for some of Northeast Indiana’s largest commercial buildings, local bridges and thousands of new homes. We are committed to the industry and it shows through our products and service.
