Underground Construction & Utility Underground
Trenchless utility installation for developers, builders, municipalities, and industrial sites — on your schedule, to your spec.
Sloan Underground Construction has been running underground construction and commercial utility underground projects across the Carolinas since 1965. Developers, general contractors, municipalities, industrial sites, ISPs, and utility providers call us for subdivision utilities, commercial pad-site installs, municipal infrastructure, fiber backbone, and industrial bores. We work GC-managed schedules, coordinate with other subs, and deliver as-builts at closeout.
