What is utility underground work?

Utility underground work is the installation, repair, and replacement of below-ground infrastructure that delivers essential services to homes and businesses: water supply, wastewater removal, natural gas, electrical power, and telecommunications. Sloan Underground Construction specializes in trenchless installation methods that place these utilities underground without destroying the surface above.

Why Choose Trenchless for Underground Utility Installation

Traditional utility installation requires continuous open-cut trenching — cutting through driveways, roads, landscaping, and hardscape for the entire length of the utility run. The installation is straightforward, but the surface damage and restoration costs are substantial.

Trenchless utility installation uses horizontal directional drilling to bore a steerable underground path between two small entry and exit pits. The utility line is attached to the drill head and pulled back through the completed bore. The surface above remains untouched.

For projects where the utility must cross under roads, driveways, creek beds, mature landscaping, parking lots, or existing structures, trenchless installation is faster, less expensive when restoration costs are factored in, and causes zero surface disruption. Sloan Underground Construction has been installing utilities trenchless across Greenville, Spartanburg, Anderson, and the Upstate SC region since 1965.

Common Questions
Underground utility answers

Utility Underground FAQ

What utilities can be installed underground?

Sloan Underground Construction installs all utility types underground: water service lines, natural gas lines, electric conduit and direct-bury cable, fiber optic cable, telecommunications conduit, sewer and drainage pipe. From residential single-line bores to large commercial multi-utility installations.

How deep are utility lines buried?

Depth varies by utility type and local code. Water lines typically run 18-36 inches deep, gas lines 18-24 inches, electric conduit 18-24 inches (deeper for high-voltage), fiber and telecom 24-36 inches, and sewer lines follow gravity grade. We confirm required depths with local code and utility companies before every job.

Do you handle permits for underground utility work?

Permit requirements vary by municipality and utility type. For utility contractor subcontracting work, the general contractor or utility company typically handles permits. For direct residential and commercial clients, we coordinate permit applications and ensure all work meets local code. Call (864) 386-1649 to discuss your project.

Can you install utilities under roads, driveways, and landscaping?

Yes — horizontal directional drilling is specifically designed for crossing under obstacles without surface disruption. We routinely bore under roads, driveways, parking lots, creek beds, foundations, slabs, and mature landscaping. Our JT-5, JT-520, and JT-2020 rigs handle all surface conditions across the Upstate SC region.
