95 Years Strong: Family Owned and Operated for 5 Generations

When Hammon T. Becken founded the company in 1927, he made sure the company was known for an intense work ethic, unwavering business integrity and a commitment to never cut corners but keep an eye on what lies around the next corner. 

Our history reflects a century of strong values, dedicated people and state-of-the-science technology committed to our products and services. 

From the early days when sand was dug by hand and sold by the bushel, to today’s high-tech methods of producing quality ready mixed concrete and aggregates for an ever-changing construction market, Cemstone has developed a tradition of consistent quality, proven performance, and growth through innovation.
