Trenchless Pipe Installation
Sewer, drainage, and utility pipe installed underground — without the trench, the tear-up, or the surface repair bill.
Sloan Underground Construction has been installing pipe trenchless across the Carolinas since 1965. Instead of digging a continuous trench, our HDD rigs bore a steerable pilot, ream it to size, and pull the new pipe through — leaving driveways, yards, and hardscape intact. Residential installs typically cost $2,000–$7,000 and finish in 1–2 days.
How is trenchless different from open-cut pipe installation?
Open-cut means a continuous excavated trench for the entire length of the pipe — through lawn, concrete, and anything else in the way. Trenchless bores underground between two small pits and pulls the pipe through. The surface above stays exactly as it was.
How Trenchless Pipe Installation Works
Trenchless pipe installation uses horizontal directional drilling (HDD). The process: a surface-launched drill rig creates an underground bore path along a planned route, a pilot hole is drilled, the hole is reamed to the required diameter, and the new pipe is attached to the reamer and pulled back through to the exit pit.
The surface stays intact — only two small pits are disturbed. That makes trenchless the right call for installations under roads, driveways, parking lots, patios, mature landscaping, foundations, slabs, crawl spaces, and waterways where open-cut would be prohibitively expensive, impractical, or outright prohibited.
Trenchless vs Traditional — Why It Wins
The math is simple. A 120-foot sewer replacement via open-cut through a driveway costs $2,000 in pipe and labor and $6,000 in driveway restoration. The same job trenchless costs $4,500 total and finishes in a day. You save money, time, and a ripped-up property.
- No driveway or hardscape destruction
- Works under mature landscaping without killing it
- Faster — most jobs wrap in a single day
- Less environmental and erosion impact

Anderson, SC →Common Questions About Trenchless Pipe
How is trenchless pipe installation different from open-cut?
Open-cut digs a continuous trench the full length of the pipe. Trenchless bores a small-diameter pilot, reams, and pulls the new pipe through underground. The surface stays intact — only two small pits are disturbed.
What kind of pipes can be installed trenchless?
HDPE and PVC sewer, drainage, water, and utility pipe from 1 inch through 12+ inches. Gravity-fed sewer laterals, storm drainage, French drains, culverts, and pressure utility pipe.
How much does trenchless pipe installation cost?
Residential installs typically $2,000–$7,000 depending on length, diameter, depth, and soil. Trenchless often costs less than open-cut when you factor in the surface restoration you avoid.
Can trenchless install pipe under existing infrastructure?
Yes. Under roads, driveways, parking lots, patios, slabs, creeks, and mature landscaping without surface disruption — one of HDD's core strengths.
