Sunroc Corporation — Cedar City Construction & Building Materials

Sunroc Corporation is one of the largest construction and building materials companies in the Intermountain West, with a significant presence in Cedar City and throughout Southern Utah. Founded in 1935, the employee-owned company provides ready-mix concrete, asphalt paving, sand, gravel, aggregates, and heavy civil construction services for residential, commercial, and public infrastructure projects across the region.

Building Materials for Southern Utah

Sunroc's Cedar City operations supply the essential building materials that fuel Iron County's growth. Their ready-mix concrete plants produce custom mixes engineered for Southern Utah's climate conditions — accounting for high temperatures, low humidity, and the freeze-thaw cycles common at Cedar City's 5,800-foot elevation. Contractors rely on Sunroc's consistent quality and reliable delivery schedules for foundations, flatwork, structural concrete, and decorative applications.

Heavy Civil Construction

Beyond materials supply, Sunroc's construction division handles major civil infrastructure projects including road construction, highway paving, utility installations, site development, and earthwork. Their crews have contributed to significant public works projects throughout Southern Utah, from I-15 corridor improvements to municipal water and sewer infrastructure that supports the region's rapid population growth.

Asphalt & Paving Services

Sunroc operates asphalt plants and paving crews that serve Southern Utah's expanding road network. From residential driveways and commercial parking lots to county roads and state highway projects, their asphalt division provides mix design, production, and installation services. The company's integrated approach — controlling aggregate production, asphalt mixing, and paving operations — ensures quality control from raw material to finished surface.
