Foundation and Basement Excavation

Foundation and Basement Excavation in Bozeman

Ofaolains digs footings, crawl spaces, and full basements to plan depth and dimension across Bozeman and Gallatin County. We over-dig for forms where the plan needs it, manage the spoil to a stockpile or haul-off, and leave a level, compacted bearing surface that a concrete crew can pour on the same week. The hole is only right when the bottom is clean and the elevation is true.

Why the Ground Dictates the Dig

Valley soil is not uniform. A basement that starts in silty loam can hit river cobble a few feet down, and a spring water table can put water in the hole overnight. We plan for both, keeping a pump ready and shaping the cut so the walls stay stable. Twenty years on this ground means fewer surprises once the bucket is in.

Our Process

We locate utilities through 811 two business days ahead, then excavate to plan depth, holding the over-dig the forms need. We compact the bearing surface, confirm the elevation, and cut a clean, square bottom for footings. Backfill goes in as controlled lifts once the concrete has cured, tested to density so nothing settles later.
