Road Mix, Sand and Gravel Delivery in Bannock County, ID
Idaho Rock Supply handles gravel, stone and aggregate delivery in Bannock County, ID. Road mix is the base material this part of Idaho is built on, and it is the load most ground here starts with.
It goes under driveways, parking pads, shop floors and shed slabs across the Southeast Idaho valleys and the Bear River country.

Materials Delivered in Bannock County
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. Idaho yards write it up two ways.
State highway work follows the ITD Standard Specifications for Highway Construction, where Section 703.04 covers Aggregate for Untreated Base, Treated Base and Road Mix. 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.
That is how material is described here, nothing more.
Round rock and cobble cover decorative beds, dry creek beds and water features. Fill dirt brings a low spot up before a base course goes on top, and garden soil fills raised beds where the native ground is too thin to plant into.
Ground Conditions Across Bannock County
Base and paver work runs from the spring thaw into the fall. The window is shorter in the higher valleys than it is down on the valley floors, so timing a delivery matters more than the material list on a tight schedule.
Across the Southeast Idaho valleys and the Bear River country, the ground is loess and silt loam over limestone, sandstone and older sedimentary rock. Valley alluvium sits deep in places, and coarse gravel fans spread where the canyons open out.
Water comes off the ranges onto the valley floors faster than silt loam can take it. Alluvial fans carry sudden flows across building ground, and low land stays wet into early summer.
That is where a clean drainage layer does the work instead of a fines-bearing base.
Snowmelt and thunderstorm runoff cut canyon roads and fans, and gullying shows up on grazed and cropped slopes. Rip rap on banks, outlets and cut slopes takes that energy.
Valley winters freeze hard and swing either side of freezing, with heavy heaving at the spring thaw. Around Pocatello, about 30 inches is the frost depth figure commonly used.

Choosing the Right Material
Bannock County sits on the same ground as Franklin County, both in the Southeast Idaho valleys and the Bear River country. Loess and silt loam over limestone and sandstone, deep valley alluvium, and coarse gravel fans at the canyon mouths.
The base and drainage choice carries across that line unchanged.
Bingham County is different. Its ground runs to young basalt flows with thin soil over them, river sand and gravel, and wind-laid silt and dune sand.
Over basalt, a fines-bearing base has little to tie into, so pit run as sub base under road mix does more of the work.
Power County spans more than one zone, covering both the Southeast Idaho valleys and the Bear River country and the Upper Snake River Plain. Where its ground turns to basalt and sand, treat it as you would Bingham County ground.
