Profile Draft

Suncore Construction & Materials — known until mid-2025 as Sunroc Corporation — operates one of the largest civil construction and materials platforms in Southern Utah from its yard at 1825 East 3850 South in St. George. The company is a subsidiary of Spanish Fork-based Clyde Companies, Inc., a multi-generational Utah construction holding group whose other operating brands include Geneva Rock and W.W. Clyde. The St. George operation has been the primary materials and paving arm in Washington County for years and announced its rebrand to Suncore in July 2025 to consolidate naming across the seven-state Intermountain West footprint where the firm operates.

For 435-area work, Suncore brings a deep capabilities stack: roadway excavation and grading, underground utility construction, structural concrete, ready-mix delivery, asphalt production and paving, and aggregate supply. The St. George branch produces ready-mix concrete and asphalt locally and supplied work on the SR-18 passing lanes project completed ahead of the 2022 Ironman World Championship — a job that included rock-blasting during initial excavation when crews encountered unanticipated bedrock. The company is a longstanding member of the Associated General Contractors of Utah, where it is listed under excavating, utility construction, highway construction, foundations, tilt-up, and industrial piping categories.

Suncore is best understood as the heavy-civil and materials backbone for large public and commercial projects across Washington and Iron counties: subdivision mass grading, UDOT roadway packages, municipal utility extensions, and tilt-up commercial pads. The firm's scale, vertical integration (its own pits, plants, and trucking), and Clyde Companies parentage place it in a different competitive tier than owner-operator excavation outfits — useful context for a directory listing pointed at end customers trying to right-size a contractor to a job. Smaller residential dirt-work jobs are not its typical lane.

Unresolved Questions

  • Specific Utah DOPL contractor license number(s) and current expiration status.
  • Local Southern Utah employee headcount and equipment count distinct from total Clyde Companies fleet.
  • Whether the St. George branch is taking on residential/private excavation work post-rebrand or remains primarily commercial/public.
