Gravel, Stone and Soil for Benewah County, ID
Idaho Rock Supply handles gravel, stone and aggregate delivery in Benewah County, ID. Road mix is the base material most ground here is built on, and it is what Idaho yards call crushed base with the fines left in so it locks up under a roller.
It goes under driveways, parking pads, shop floors and shed slabs. Order online by the ton or the yard and a dump truck tips the load on site.

Materials delivered in Benewah County
For a driveway, start with road mix as the base and top it with driveway gravel on a long rural approach. For a patio, bed pavers on washed concrete sand and set the surface with 3/8 chip.
For a drain, use drain rock: clean angular rock for french drains, foundation drains, drywells and downspout runs. Pit run is unprocessed gravel straight from the pit, used as sub base, structural fill and for raising grade.
Road mix is also written up on plans as crushed aggregate, in Type I and Type II under the Idaho Standards for Public Works Construction.
State highway work follows the ITD Standard Specifications, where Section 703.04 covers Aggregate for Untreated Base, Treated Base and Road Mix and is the source of the 3/4 inch minus gradation.
A contractor ordering 3/4 minus and a homeowner ordering road mix are asking for the same load.
Ground conditions across Benewah County
Across the Panhandle forest and glacial ground, volcanic ash sits over windblown loess in the forested uplands, with a dense fragipan below it and glacial till on the ridges. That fragipan is close to watertight, so winter rain and snowmelt collect above it and sit near the surface through the wet months.
An under-built base over that ground pumps and shifts in spring. Pit run as sub base under road mix gives water somewhere to move before the base course goes on.
Rain on snow and spring melt cut steep forest and logging roads, and ash-capped soil moves fast once the forest litter is stripped off. Rip rap armors creek banks, culvert outlets and cut slopes against snowmelt and cloudburst runoff.
Wet ground from late fall through spring limits work here more than cold does. Base and paver work waits for the ground to drain, and the dependable window is midsummer into early fall.
Wet Pacific winters freeze and thaw again and again rather than locking up once, which heaves gravel drives and breaks up unpaved surfaces every spring. Frost depth is set by the local building official.
Choosing the right material
Kootenai County and Shoshone County sit on the same Panhandle forest and glacial ground as Benewah County. The ash, loess, fragipan and till are the same, so the base and drainage choices carry over unchanged.
Latah County is different. It sits in North Central Idaho on the Palouse hills and the Clearwater and Snake canyons, where deep windblown loess lies on Columbia River basalt.
That loess is finer and holds water differently from ash over loess with a fragipan under it. On ground like that, drainage matters more than depth alone, and drain rock or pit run under the base does more work.
