What Idaho Materials & Construction does
Idaho Materials & Construction is a vertically integrated construction materials and services provider serving southern Idaho from Meridian, ID. The company was formed through the successive combination of Idaho Sand & Gravel (founded 1972 by Vern and Hanni Hinkle in Boise), Idaho Concrete Company (tracing to the early 1900s under founder George Jesson), and International Stone, and now operates as a division of Staker Parson Companies (Ogden, UT). Its core operations include ready-mixed concrete production, asphalt manufacturing and paving, aggregate processing, decorative and colored concrete, and full construction services encompassing site work, mass excavation, road construction, gravel operations, and trucking. The company owns and operates three asphalt plants located in Nampa, Boise, and Twin Falls, providing regional supply coverage across its service area.
The business serves three primary customer segments: highway and infrastructure projects (the largest), commercial construction, and a long tail of residential subdivision and retail/landscape customers. Customer acquisition is sales-led, relying on a website-based quote request system and dedicated dispatch phone lines for Concrete, Aggregate, and Landscape Center divisions. Pricing is quote-based with no public disclosure, and revenue is generated through one-time project contracts ranging from small subdivision work to multi-million dollar highway and commercial developments. A notable active engagement is the Boise State University ESI Construction Management Building, a mass-timber educational facility being delivered with Engineered Structures Inc. and recognized with a 2025 Outstanding Project Award from Learning By Design.
The company employs 11-50 people and operates as a private subsidiary of Staker Parson Companies, a diversified construction materials group. Its go-to-market is relationship-driven and local, with no disclosed digital platform, no AI/ML capabilities, and no active funding activity. Competitive positioning rests on multi-plant regional distribution, 50+ years of operating history, and vertical integration across materials production and construction services.

- Western Rock Products: Sister Staker Parson entity operating aggregates and asphalt paving in Utah/Nevada; same integrated materials-and-construction model as Idaho Materials & Construction, making it the closest operational comparator.
- Staker Parson Materials & Construction: Sister operating company under Staker Parson Companies; offers the same vertically integrated aggregate, asphalt paving, ready-mix, and site work services that Idaho Materials & Construction provides, but serves northern Utah and southern Idaho areas outside its footprint.
- Burdick Materials & Construction: Sister Staker Parson entity serving northern Utah with aggregates, asphalt, ready-mix, and construction services—directly parallel offerings to Idaho Materials & Construction under a common parent.
- Hales Sand & Gravel: Sister Staker Parson aggregate and construction services company headquartered in Utah; identical combined materials-supply and site-work business model as Idaho Materials & Construction.

- Granite Construction: Large publicly traded heavy civil contractor with vertically integrated aggregates and paving operations in the western U.S.; directly comparable on highway construction and site development, though vastly larger in scale.
- Knife River Corporation: Publicly traded heavy civil construction and materials producer operating across the western U.S.; aggregates, asphalt, and construction services directly mirror Idaho Materials & Construction's offerings but at much greater scale and geographic reach.
Others
