SRI  Supplier of Sand and Gravel Products

Welcome Plant

SRI was established in September, 1990, and is located in Marysville, California, 60 miles north of the state capitol Sacramento, California. SRI operates year round, and mines some of the world’s finest aggregate from the Yuba Gold Fields in Yuba county.

The chemical and physical characteristics of the Yuba Gold Fields resource enables us to manufacture multi-functional products. One of the most unique aspects of this reserve is the full spectrum size range (diameters) of quality aggregate, and the wide variety of reserves available from a single source.

At SRI, we conduct our own state-of-the-art washing, screening, drying, grading, and packaging operations. SRI products are designed, tested and manufactured to meet stringent specifications for use in a variety of industries, and are the only aggregate products in California approved by the National Sanitation Foundation.

SRI has a long history of domestic and overseas shipping experience. Our customers are located throughout the United States, Canada, the Pacific Rim, South America, Europe, and the Middle East, and we are committed to providing them with outstanding service and an excellent product.
