Granite Rock Company Revenue and Competitors

Granite Rock Company's roots lie deep in the history of the central California coast. In fact, its story began more than 200 million years ago, when a mass of molten granite began to push up from the depths of the earth through limestone, sandstone and clay on the bed of an ancient ocean. The granite cooled, contracted and cracked, and was folded, broken, crushed and uplifted as the Pacific Plate slowly drifted by the continent of North America. The fortuitous location of the granite directly upon the San Andreas Fault would ease future mining of this pre-fractured rock.
