Watsonville-based Graniterock started in 1900 mining rock from a quarry in Aromas. The family-owned company has expanded beyond the quarry into one of San Francisco Bay Area's most respected materials, transportation and construction companies with more than 800 employees. The company has offices in Santa Cruz, Monterey, San Benito, Santa Clara, San Mateo, San Francisco and Alameda counties.
We go the extra mile for our customers and say "yes, we will" in nearly every case. Our customers are committed to doing business with Graniterock because they trust our people.
