Concrete, Asphalt & Restoration from 406 Underground
Concrete work covers flatwork — sidewalks, patios, driveways and slabs — plus footings, curbs, walls and drainage inlets, with broom, stamped and colored finishes.
Asphalt services include crack fill and repair and small pothole repair using products made for harsh Montana winters. Landscape restoration ranges from resetting pavers to renewal pruning overgrown shrubs.

Why it pays
- Restoration by the same crew that dug
- Products for Montana winters
- Small jobs welcome
“The crews not only provide accurate bores, but also take responsibility for their actions and clean up after themselves without being asked when leaving a jobsite. Four O Six is also proactive in locating utility crossings… Montana owned and operated, this company has a family touch to it and it shows in their desire to do a good job at a minimal cost.”
— Rob Hanson, PE, Contractor for NorthWestern EnergyQuestions
