Graniterock Celebrates 125 Years of Building Infrastructure and Community

Founded on 'Valentine’s Day' in 1900, the family-owned construction and construction materials company’s commitment to excellence has cemented its legacy as a cornerstone of the Central Coast and beyond.

What began as a small granite quarry in Aromas, founded by Arthur R. Wilson, has grown into a multifaceted engineering and construction materials company that plays an essential role in building California’s highways, bridges, airports, schools and neighborhoods.

From its earliest days supplying crushed granite for the Southern Pacific rail line, to launching the first hot mix asphalt plant in the state of California in 1935, to winning the 1992 'Malcolm Baldrige Award' – the nation’s highest award for quality, Graniterock has long been at the forefront of innovation in construction materials and services."
