About

Family Owned & Operated Canyon Rock has been a leader in the industry in supplying quality aggregate and concrete since the 1970s. The Trappe family originally from Freestone CA owned a dairy ranch and would purchase materials from Canyon Rock for their roads. In 1972 Canyon Rock was for sale and purchased by Adolph Trappe and has been family owned and operated ever since. Adolphs son Wendel and his wife Gwen have kept Canyon Rock as a family-operated business over the years and their three children are now a vital part of the company as well. Canyon Rock has been built by three generations with hopes to soon have its fourth generation learning the business. Aggregate is a vital part of structures that support everyday life and it is important to have local sources. Canyon Rocks goal is to produce aggregate and concrete products in the most efficient sustainable way possible into the next generation while adapting to a changing climate and evolving demand all while making the best use of people and technology to make products in which we and our community are all proud.
