The work is trenchless: water, gas, electric, fiber, conduit, sewer and drainage lines installed by horizontal directional drilling. Call (864) 386-1649.

Horizontal directional drilling (HDD) is a trenchless method of installing underground utilities (water lines, gas lines, electric cables, fiber optics, and conduit) without digging an open trench. A drill rig bores a steerable pilot hole underground along a planned path, then pulls the utility line back through the bore. The only surface disturbance is a small entry pit and a small exit pit.

Directional boring is better than trenching for most residential and commercial projects because it preserves driveways, landscaping, lawns, and hardscape that an open trench would cut through. Most residential jobs finish in a single day, and there is no surface restoration bill afterward. Trenching makes sense for very short runs in open ground where surface disruption is acceptable.

Sloan Underground Construction bores under driveways, roads, sidewalks, parking lots, creek beds, and landscaped areas; that is what horizontal directional drilling is designed for. Instead of cutting through concrete or asphalt and patching it, the drill passes underneath the surface. The crew works in the clay, rock, sand, and mixed Piedmont soils found across Upstate SC.

Water lines, gas lines, electric service and conduit, fiber optic cable, telecommunications conduit, sewer and drainage pipe, and irrigation lines can all be installed with directional drilling. Sloan Underground Construction bores pipe diameters from 1 inch through 12+ inches, from a single residential water service line to a full commercial conduit package.

Most residential directional drilling jobs (a single bore for a water, gas, electric, or fiber line under a driveway or road) complete in a single day, often 4 to 8 hours from setup to cleanup. Commercial projects or longer multi-run bores typically take 2 to 3 days depending on soil conditions, bore length, and the number of utility passes. The written estimate states the expected timeline.

Residential driveway bores typically start around $1,500–$3,500 for short runs. Longer bores, commercial runs, or bores through rocky terrain scale to $4,000–$20,000+. Cost depends on bore length and depth, utility type, soil conditions, pipe diameter, and whether the bore crosses under roads, driveways, or waterways.
