Directional drilling contractors in Knoxville, TN
Horizontal directional drilling, auger boring and pipe boring in Knoxville: conduit, fiber, water, sewer and gas lines put under roads, driveways and landscaping without an open trench.
Property owners, builders and utilities in Knoxville call a boring contractor for the same reason: something has to go in the ground where the surface cannot be disturbed. Directional drilling and auger boring do that, placing conduit, duct, casing or pipe underneath roads, slabs, creeks and landscaping from entry and exit pits that are a few feet square.
In Tennessee the listed contractor is Davis Underground Solutions, Inc., based in Powder Springs, Georgia, which drills across the Southeast and quotes any mobilization up front. See Davis Underground Solutions's Tennessee drilling page for the crew, the equipment and recent projects, or call (855) 520-2670; estimates are free.

How a bore in Knoxville is done
The sequence in Knoxville is locate, plan, pilot, ream, pull. The Tennessee 811 locate marks the public utilities, the bore plan sets depth and clearances, the pilot bore is steered along that plan and tracked from above, the hole is enlarged to about one and a half times the pipe diameter, and the pipe is pulled back from the exit pit to the entry pit. Fluid returns are contained at both pits and hauled off or recycled.
Hiring a drilling contractor in Knoxville
The questions that matter when hiring in Knoxville: Has the crew bored in this soil before? Who files the Tennessee 811 ticket and the Tennessee permits? What diameter and length can the rig on this job handle? What is the plan for fluid returns, and for a bore that drifts off line? Is the price per foot or for the finished crossing? A contractor who bores for a living answers all of them without hesitation.

Questions we hear in Knoxville
How deep does a directional bore go under a road in Knoxville?+
Most road crossings in Tennessee are bored 4 to 10 feet below the pavement, deeper under state highways and railroads where the permit sets a minimum cover. The depth also depends on the pipe diameter and the bend radius the product can tolerate; a longer bore lets the crew ease down to depth and back up more gradually.
What size pipe can be installed by directional drilling in Knoxville?+
Residential and small commercial bores commonly place 1-inch to 6-inch conduit, water or gas lines. Mid-size rigs handle 8-inch to 16-inch product, and large rigs install 24-inch and larger steel or HDPE under rivers and highways. The soil and the length of the run matter as much as the rig's rated pullback.
Is directional drilling cheaper than digging a trench in Knoxville?+
For a crossing under pavement, a driveway, mature landscaping or a creek, boring is almost always cheaper once you count the cutting, backfill, repaving and restoration that a trench requires. In an open field with nothing to cross, a trench can be less. A good contractor will tell you which applies to your job.
How do I get a directional drilling estimate in Knoxville?+
