About Coullaudkoulinsky

A Bozeman Earthwork Crew Focused on the Ground Under Your Build

Coullaudkoulinsky handles land excavation for property owners and builders across Bozeman, Montana and the surrounding Gallatin County towns. Our focus is the part of the job that never shows: structural fill, tested compaction, and the subgrade that carries your slab, driveway, or foundation. We strip and stockpile topsoil, import and place engineered fill in controlled lifts, and compact each lift to a measured density so the pad does not settle after the concrete cures.

Bozeman soils and Bozeman winters are unforgiving of shortcuts. Frost drives close to four feet down on a cold year, and a pad that was not compacted to 95 percent of maximum dry density will heave and crack by the second spring. We test with standard or modified Proctor methods where the plans call for it, and we hand you the density reports an inspector wants to see.

Why Owners Call Us

• We build for the load, not the day. Fill goes in lifts and gets compacted and tested, so the grade holds for years.
• We document the work. Proctor and field density results come with the job when an engineer or the county requires them.
• We know the valley. From infill lots off Durston Road to new builds toward Kagy Boulevard, we match fill and compaction to the soil we find.
• We stand behind the grade. A licensed, insured local crew, and a real person answers the phone.
