Our History

In 1972, Vern and Hanni Hinkle founded Idaho Sand and Gravel Company to supply rock products to retail customers in the Boise, Idaho area. We soon expanded into asphalt production, paving and construction services and have asphalt plants in Nampa, Boise and Twin Falls, Idaho. We offer a complete line of services including aggregate and asphalt production, asphalt paving, road construction, site work, mass excavation, gravel operations and trucking.

Idaho Concrete Company’s history dates back to the early 1900s when founder, George Jesson, jack-of-all-trades, offered services that ranged from the manufacturing of concrete pipe, pre-cast concrete, pre-stressed concrete, ready -mix concrete, and even asphalt paving.  The company progressed through many name changes eventually becoming a ready-mixed concrete company called Idaho Concrete Company.

The two companies joined together to supply sand, rock and landscape products, ready-mixed concrete, asphalt, and construction services from a broad network of operations throughout southern Idaho.

Now, Idaho Sand & Gravel, Idaho Concrete Company, and International Stone have merged to provide an even wider range of products and services to more locations in Idaho.
