San Marcos Sand & Gravel, strategically located between Austin and San Antonio, Texas is one of the newest location to be added to the Fred Weber family.
Operated by Iron Mountain Trap Rock (a subsidiary of Fred Weber), San Marcos is surface mining selectlocations on 1,750 acres for sand and gravel to be used in the local construction market and for the aggregate needs of the Waterstone mixed-use residential/commercial development.
Our work will support the sustainable living plan envisioned by the innovative Waterstone project. The Waterstone project features culture, recreation, education, ecology and landscape in one setting that is never far from the water.
