Serving Corvallis and all of Oregon
Directional drilling contractors in Corvallis, OR
Horizontal directional drilling, auger boring and pipe boring in Corvallis: conduit, fiber, water, sewer and gas lines put under roads, driveways and landscaping without an open trench.
Most of the underground lines being installed in Corvallis today never see an open trench. Directional drilling runs a steered pilot bore between two pits, reams it to size and pulls the pipe or conduit back through in one pass. For a crossing under a Oregon highway, a railroad or a river, it is usually the only method the permit will allow.

The Willamette Valley is silt and clay over gravel with a high winter water table; Bend and central Oregon drill through basalt and volcanic rock, and the coast has sand and soft marine deposits.

How a bore in Corvallis is done
On a typical Corvallis job the crew sets up an entry pit on one side of the obstruction and an exit pit on the other, calls in the Oregon 811 ticket, and drills a pilot hole that is tracked by a walkover locator above ground. Drilling fluid, usually a bentonite and water mix, carries cuttings out, lubricates the pipe and holds the hole open in sand or soft soil. The hole is reamed to size and the product is pulled in.

Questions we hear in Corvallis
What size pipe can be installed by directional drilling in Corvallis?+
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 Corvallis?+
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 deep does a directional bore go under a road in Corvallis?+
Most road crossings in Oregon 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.
How do I get a directional drilling estimate in Corvallis?+
