Bay Area Aggregate Producers

Bay Area aggregate producers provide aggregates for many uses other than concrete, including asphalt concrete, road bases, and subbases. The aggregate production business in the Bay Area has been subject to the same consolidation stresses affecting most industries, blurring the lines between concrete supplier and aggregate producer. Most companies in the aggregate business are also supplying cement, ready-mix concrete, or producing asphalt concrete. Recent changes in the industry include the acquisition of RMC Pacific (a ready-mix supplier and aggregate producer) by CEMEX, an international cement, ready-mix and aggregate producer founded in Mexico, and Hanson Aggregates West’s purchase of Mission Valley Rock, including the Sunol Plant.
