Summit Materials

Summit Materials produces and supplies aggregates, cement, ready-mix concrete and asphalt, and offers paving, construction and recycling services. Its website describes aggregates quarried in the United States and Canada, asphalt made partly from recycled material, and ready-mix used for everything from curbs to countertops. The company presents itself as a national materials supplier with local roots in each community it serves.

The company is headquartered at 1801 California St. in Denver, and its listed phone line is a general contact number. Its materials are sold to contractors and builders for public and private infrastructure, so most work is project-based rather than walk-in retail. Customers looking for a specific quantity or delivery should call the office directly.
