Canyon Rock

The Quarry that's Family-Operated
and Community-Minded


For over 40 years, our family has provided quality rock, concrete mixes, and sand for Sonoma County and its outlying areas. Our rock is in your roads, your stores, your hospitals, your playgrounds, your parks, and your kids' schools. From freeways to pathways, from ditches to decorations, Canyon Rock has helped build the foundation of this community. And we're especially proud of that – because it's our community, too.
