Order Road Mix and Crushed Stone in Butte County, ID
Idaho Rock Supply brings gravel, stone and aggregate delivery in Butte County, ID. Start with road mix where water has nowhere to go.
Young basalt sits close to the surface across the Upper Snake River Plain and the eastern farm valleys, so soil stays thin over rock and meltwater ponds instead of soaking away.
Road mix, also called 3/4 road mix or 3/4 minus, is crushed base with the fines left in so it locks up under a roller. Order it online and a dump truck tips it on site.

Time the drop for the working season. Frozen ground stops compaction from late fall to early spring, and the dependable base and paver window runs from late spring into early autumn.
Materials delivered in Butte County
Road mix carries the base work here. It is what Idaho yards call crushed base with the fines left in, and it goes under driveways, parking pads, shop floors and shed slabs.
On public works plans the same material is written as crushed aggregate by type, and 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.
City, county and highway district work is usually written to the Idaho Standards for Public Works Construction, whose Section 802 covers crushed aggregate in Type I and Type II. Those are how material is specified in Idaho.
Below the base, pit run is unprocessed gravel straight from the pit, rock and fines mixed at whatever sizes the pit gives. Use it as sub base under road mix, as structural fill, or to fill holes and raise grade.
It is not a finished surface.
For drainage, drain rock is clean angular rock for french drains, foundation drains, drywells and downspout runs. Rip rap armors creek banks, culvert outlets, canal banks and cut slopes against snowmelt and cloudburst runoff.
Where a finer surface is wanted, 3/8 chip tops a compacted base on pathways, and screened top soil builds up lawns and beds over thin desert soil and stony ground.
Ground conditions across Butte County
Start with the season and the timing of the drop. Frozen ground stops compaction from late fall to early spring, so plan base and paver work for the window that runs from late spring into early autumn.
Then look at what the ground does with water. Basalt close to the surface leaves water nowhere to go, so drives and footings sit on thin ground over rock.
Canal seepage and heavy spring irrigation lift the water table under low farmed ground.
That shapes the layers. Pit run goes down first as sub base or fill, road mix goes on top as the compacted base, and drain rock handles the water that has to leave.
Spring runoff off the Caribou and Centennial ranges moves a lot of water at once. Wind moves dune sand and dry field soil, and canal banks and culvert outlets wash out during snowmelt, which is where rip rap earns its place.
Frost matters too. The coldest sustained winters of settled Idaho bring long hard freezes at 4,500 feet and above and a sharp heaving thaw in spring.
About 30 inches is the figure commonly used at Idaho Falls and through the upper Snake River towns, and the local building official sets footing depth.
Choosing the right material
Custer County sits in Central Idaho, over thin, coarse soils on the granite of the Idaho Batholith. That ground weathers to sandy Stone Screenings, with glacial till and moraine around the valley heads.
Butte County ground is young basalt with thin soil over it, so base material here has to lock up over rock rather than settle into Stone Screenings.
Jefferson County and Clark County sit in Eastern Idaho on the same ground region as Butte County. The ground is the same: young basalt flows with thin soil over them, river sand and gravel, wind-laid silt and dune sand, and deeper irrigated silt loam on the farmed ground.
The base and drainage choices carry over.
Match the material to the job. Road mix is a compacted base for drives and pads.
Pit run is sub base and fill. Drain rock and rip rap move water and hold banks.
Chips and top soil finish surfaces.
