Crushed Base Course, Sand and Gravel Delivery in Powder River County, MT
Montana Rock Supply brings gravel, stone and aggregate delivery in Powder River County, MT to the job you are planning, whether that is a driveway, a shop pad or a drainage run. Most of it starts with crushed base course, the 3/4 minus material Montana yards sell as the standard base.
Ground here is bentonite-rich gumbo clay weathered off marine shale, so what you put down and how water leaves the site decide how the job holds up.
Materials Delivered in Powder River County
Crushed base course is the base material for drives, shop pads, parking areas and shed bases.
In Montana it is specified as crushed base course, under Section 701.02.4 of the MDT Standard Specifications, where grades are named by nominal top size: Grade 5A at 2 inch minus, Grade 6A at 1 1/2 inch minus, and Grade 7A at 3/4 inch minus.
City and county work is often written against Section 02235, Crushed Base Course, of the Montana Public Works Standard Specifications.
Sand and soil round out a job. Mason Sand goes into brick and block work and paver joints, and Washed Sand levels and beds flatwork and pavers.
Garden Soil fills raised beds where native clay or gravel will not do on its own.
For decorative work, Yellowstone River Rock and Large River Rock handle beds, borders and dry creek beds. Shredded Mulch holds on slopes and in wind better than nuggets, which matters on open ground.

Ground conditions across Powder River County
Gumbo is the driver here. Bentonite clay swells and turns greasy as soon as it wets up, then cracks open when it dries, so water sits on the surface and unsurfaced roads go soft.
Cloudbursts run straight off into the coulees, and that fast water cuts gullies and rills in shale and clay badlands. Slumping shows up along the Missouri Breaks, and bank scour works on the Yellowstone, Powder and Tongue.
Work follows dry ground. Spring breakup and heavy rain make gumbo roads impassable, and midsummer into early autumn is the dependable window for a delivery and a build.
Winters are cold and dry with deep frost and wide day-to-night swings. Ground that thaws on a chinook afternoon and refreezes overnight heaves gravel roads and opens up drives.
Frost depth figures published across Montana run from about 36 to 60 inches, with eastern plains figures usually quoted at the lower end, and the local building department sets footing depth.
Choosing the right material
Big Horn County, Custer County and Rosebud County all sit on the same ground region as Powder River County: bentonite-rich gumbo clay weathered off marine shale, with badlands, scoria beds, the broken ground of the Missouri Breaks, and sand, gravel and cobble terraces along the Yellowstone, Missouri and Powder.
The ground is the same, so the material reasoning is the same. A compacted crushed base course carries a drive or a pad, washed rock takes water away from a foundation, and riprap armors a slope or an outlet where runoff hits hard.
