About Us

In 1972, Vern and Hanni Hinkle founded Idaho Sand and Gravel Company to supply rock products to retail customers in the Boise, Idaho area. The company soon expanded into asphalt production, paving and construction services.

The company has asphalt plants in Nampa, Boise and Twin Falls, Idaho. ISG offers 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.

Idaho Concrete Company serves customers with their concrete and aggregate needs from a broad network of plants throughout southern Idaho.
