Horizontal Directional Drilling in SC & NC
Trenchless underground boring under roads, driveways, and waterways — without tearing up your property. 60 years, 4 generations, a flawless safety record.
Sloan Underground Construction has been installing trenchless utilities across the Carolinas using horizontal directional drilling since 1965. HDD bores a steerable pilot hole underground, reams it to size, and pulls water, gas, electric, fiber, or conduit back through — without an open trench. Most residential bores complete in a single day; typical pricing runs $1,500 to $3,500 for a short driveway bore and scales with length, diameter, and soil.
How much does horizontal directional drilling cost in SC?
A short residential bore under a driveway typically runs $1,500–$3,500. Longer bores, larger-diameter pipe, rock or mixed soil, and bores crossing roads or waterways push costs to $4,000–$20,000+. We write free, on-site estimates with a clear line-item breakdown — usually within 24 hours.
What Is Horizontal Directional Drilling and How Does It Work?
Horizontal directional drilling — HDD, directional boring, or trenchless drilling — is a steerable method of installing underground pipe, conduit, or cable without an open trench. A surface-launched drill rig creates an underground bore path following a planned route. A pilot hole is drilled along the path, then enlarged (reamed) to the required diameter, and the product pipe is pulled back through the bore.
The only surface disturbance is a small entry pit at the drill end and a small exit pit at the pullback end. Everything else — the driveway, the landscaping, the road above — stays untouched. That's why HDD is the default method for crossing under obstacles where open excavation would be impractical, costly, or outright prohibited.
Our crew runs a Ditch Witch JT-5, JT-520, and JT-2020 fleet, which handles pipe diameters from 1 inch up through 12+ inches and bore lengths from a 40-foot driveway crossing to 600-foot-plus commercial runs. We steer through clay, rock, sand, and the mixed Piedmont soils common across Upstate SC.
Why HDD Beats Open-Cut Every Time
- Minimal surface disruption — no torn-up lawns, driveways, or landscaping.
- No open trenching — eliminates excavation, backfill, and expensive surface restoration.
- Works under obstacles — roads, driveways, foundations, creeks, and parking lots.
- Faster — most residential bores wrap in a day; commercial runs on accelerated timelines.
- Cost-effective — less labor, less equipment, no surface repair.
- Lower environmental impact — less soil disturbance, less erosion.
How We Run a Directional Drilling Job
Site Survey & 811 Locate
Walk the property, call 811, identify obstacles, and map the bore path.
Pilot Bore
The JT-series rig steers a small-diameter pilot along the planned underground path.
Reaming & Pullback
Enlarge the bore to the needed diameter; attach and pull the product pipe through.
Restoration
Restore the entry and exit pits; clean up; leave the site better than we found it.
What We Install With HDD
Water Lines
New service lines, main replacements, and irrigation runs for residential and commercial properties.
Gas Lines
Natural gas service for homes, businesses, and new construction developments.
Electric & Conduit
Underground electrical conduit and direct-bury cable replacing or supplementing overhead power.
Fiber Optic
High-speed fiber infrastructure for ISPs and telecom providers.
Telecom Conduit
Empty conduit runs for future utility installation and multi-use pathways.
Sewer & Drainage
Trenchless sewer and drainage installation without destroying hardscape.
HDD Across the Carolinas
We run directional drilling jobs across 15 cities including Greenville, Spartanburg, Anderson, Pickens, Oconee, Laurens, Newberry, Lexington, Aiken, and into Asheville, NC. From downtown Upstate properties to rural foothills sites, we get there with the right rig for the job.

How much does horizontal directional drilling cost in SC?
A short residential bore under a driveway typically runs $1,500–$3,500. Longer bores, larger-diameter pipe, rock or mixed soil conditions, and bores crossing roads or waterways scale the cost to $4,000–$20,000+. Every job gets a free, written estimate with a clear line-item breakdown.
How long does a typical HDD project take?
Most residential HDD jobs wrap in a single day — often 4 to 8 hours from setup to cleanup. Commercial or multi-run projects take 2 to 3 days depending on length and soil. We give you a firm timeline during the estimate so there are no surprises.
Will directional drilling damage my lawn or driveway?
No. HDD creates a small entry pit at one end and a small exit pit at the other — the bore runs entirely underground between them. Driveways, sidewalks, mature landscaping, and lawns stay intact. We restore both pits at the end of the job.
What utilities can be installed with HDD?
Water lines, gas lines, electric service and conduit, fiber optic cable, telecommunications conduit, sewer and drainage pipe, and irrigation lines. Pipe diameters from 1 inch through 12+ inches are routinely bored with our Ditch Witch JT-5, JT-520, and JT-2020 rigs.
