Directional Drilling in Helena, MT

Helena is home. 406 Underground has been based here since 2013, so a Helena bore means a short drive, a quick site look and a crew that knows the valley.

Directional drilling and boring in Helena

Most Helena jobs are what you'd expect in a growing valley town: a service line bored under a driveway or street, conduit run through a finished yard, a well-to-house line pushed under a county road, or utility work in older neighborhoods where the records don't always match what's in the ground.

We take the single bore for your crew or the whole underground scope — locate, pothole, bore, pull back and restore — and our concrete division can put back sidewalks and driveways that get cut.

It's the same horizontal directional drilling (HDD) we run everywhere: locate and pothole, steer the pilot bore, ream, pull back the product and restore the entry and exit. Sidewalks and driveways cut for the work can be put back by our concrete division.

Ground conditions around Helena

  • Sandy gravels with cobble are common on the Helena Valley floor, which drives tooling and drilling-fluid choices.
  • Toward the foothills and the south side of town, rock is more likely at shallow depth, so bore depth and rig size get planned around it.
  • Older neighborhoods have crowded, sometimes poorly documented utilities — every crossing gets potholed before the bore.
  • Deep winter frost: water lines go in below frost depth to the owner's or utility's spec.

General conditions only — every site is different, and we look before we quote.

Typical crossings

  • City streets and alleys
  • County roads and highway right-of-way (I-15, US 12, US 287)
  • Ten Mile Creek, Prickly Pear Creek and valley irrigation ditches
  • Driveways, lawns and landscaping on residential services
  • Wells to homes and shops on rural lots

How a Helena job gets scoped

Call or send the address, what's going in (product and size), rough footage and what it crosses. Because we're local, we can usually look at the site before quoting. A Montana 811 locate goes in before any digging, and city, county or state right-of-way permits get sorted out with the owner up front.

Send the details
