What HK Contractors does
HK Contractors, Inc. is a vertically integrated road construction and building materials supplier headquartered in Idaho Falls, Idaho, operating as a subsidiary of CRH (formerly Oldcastle Materials). The company traces its origins to 1950 when George Hartwell founded Hartwell Excavating, and it took its current form on July 25, 1975, through the merger of Hartwell Excavation and Kennaday Paving. HK Contractors was acquired by Oldcastle Materials on November 5, 2007, and rebranded under the CRH umbrella in 2018.
The company produces and supplies aggregates (sand, crushed river rock, screened round river rock), hot mix asphalt using Superpave specifications, ready-mixed concrete, and an extensive line of decorative landscape products including the trademarked Perma Bark® brand. Construction services span excavation, utility installation, paving, road reconstruction, subdivision development, and commercial site work, executed through asphalt plants, aggregate mining operations, and a heavy equipment fleet. Operations extend across northern Idaho, Montana, and Wyoming, with offices in Idaho Falls (headquarters and Landscape Center), Rexburg, and Teton.
HK Contractors serves three primary customer segments: government agencies (Idaho Transportation Department, National Park Service, Federal Highway Administration), commercial developers and general contractors, and residential consumers. Government work is secured through competitive project bidding on federal and state infrastructure contracts; commercial and residential developer work is delivered through direct sales and project bidding; and residential consumers purchase landscape materials at the Idaho Falls Landscape Center or through the company's customer portal at myhkcontractors.myamatportal.com. Revenue is project-based and transactional, with pricing quoted per ton, cubic yard, or bag and no publicly disclosed price list. Marquee project credentials include the $100M+ Yellowstone River Bridge, the Canyon to Tower Phase III mainline reconstruction in Yellowstone National Park, and the I-15 Rose IC to N. Lava Rocks highway project.
