Quality and consistency. Family and community. Hard work and integrity. These are the cornerstone of Capitol Aggregates and the way we do business. They are words that have guided us since our first stone was mined over fifty years ago.
Zachry Construction Corporation welcomed Capitol Aggregates into its family of companies in 1957 to meet product demand when building the Bergstrom Air Force Base airport located in southeast Austin. Capitol Aggregates has grown into a dynamic enterprise consisting of multiple cement and aggregate operations across the state of Texas.
