Crushed Stone, Sand and Gravel in Kevin, MT
Montana Rock Supply handles gravel and aggregate delivery in Kevin, MT for contractors and homeowners alike. A builder working a shop pad and a family redoing a drive both need the same thing: the right material, sized correctly, tipped on site.
In this part of Toole County that usually starts with crushed base course, the 3/4 minus base that carries a drive or a parking area.
You choose the quantity by the ton or by the yard, and each product page has a calculator to help size the load. Then a dump truck tips it where you need it.
Materials for Kevin Projects
Base and driveway surfacing come first here, because that is what most ground in this county needs before anything else can sit on it. Crushed base course, also called 3/4 crushed base course or 3/4 minus, is the standard Montana base material.
It compacts into a hard, load-bearing surface for driveways, shop pads, parking areas and shed bases. Order it by top size, and 3/4 minus is the common one.
For a finished driving surface rather than a base, road mix is the other half of the pair. Montana road mix, sometimes just called driveway gravel, carries enough fines and clay binder to pack hard under a roller.
It goes down as the surface on a drive or a county-style lane.
Underneath either of those, pit run does the heavy lifting. Pit run gravel is unprocessed pit gravel, and it is not crushed.
It is for deep fill, raising grade, and sub-base under a crushed base course or a road mix surface, not for a finished driving surface.
Water is the other thing a Kevin drive has to answer for, and that is where washed stone comes in. Washed rock, also called drain rock or 3/4 clean, has the fines washed out, which is the whole point in a French drain, a curtain drain, a foundation drain or a downspout run.
For finer drainage, trench bedding or a tight topping over a compacted base, look at 3/8 inch crushed rock. Natural Pea Gravel, the rounded 3/8 washed stone, suits walkways, play areas and dog runs.
Sand and soil round out a project. Washed sand beds and levels under flatwork and pavers, and mason sand is for brick and block work, paver joints and play sand.
Screened topsoil goes over thin or stony native ground for lawns, grading and bed prep, and garden soil is for raised beds and planting areas where native clay or gravel will not do on its own.
Ground and Conditions in Kevin
Start with where the water goes, because on the Hi-Line and the northern glaciated plains that question decides the material. The ground across this region is glacial till over shale, a mix of clay, gravel, sand and silt left by the ice and by glacial lakes.
Much of it is heavy and slow-draining.
Flat ground plus heavy till means snowmelt sits. It ponds on subsoil that is still frozen, and a semi-arid year broken by a few intense summer storms adds a second dose of water all at once.
A drive built on ground like that needs a base that drains and a surface that sheds, which is why crushed base course and road mix work as a pair.
Wind on bare ground is the other force at work, along with sheet and gully erosion in the coulees. Riprap armors stream banks, culvert outlets, coulees, ditches and slopes against spring runoff.
Shredded mulch holds on slopes and in wind better than nuggets, which matters on open ground.
The working season is short. Frost is in the ground from late autumn into spring, and compaction waits for it to come out.
Chinook thaws cycle the surface without taking the frost fully out until spring, so timing a base course matters as much as the material itself. Frost depth figures published across Montana run from about 36 to 60 inches, and the northern plains sit at the deep end of that range.
The local building department sets footing depth.
