Road Mix, Sand and Gravel Delivery in Bonner County, ID
Idaho Rock Supply brings gravel, stone and aggregate delivery in Bonner County, ID to driveways, drain runs and planting beds. Road mix is the base to start with here, because the ground under it is often ash over loess with a tight layer below.
Water sits above that layer through the wet months, so a drive or pad needs a base that sheds and locks up. The same yard carries the sand, soil and rock that finish the job.
Materials Delivered in Bonner County
Base material comes in two forms here. Road mix is crushed base with the fines left in, so it locks up under a roller.
Pit run is unprocessed gravel straight from the pit, used as sub base and structural fill rather than a finished surface.
Around the base sit the clean and decorative materials. Each one has a job it does well and a job it does not.
Road mix is also called 3/4 road mix, road base or crushed base. A contractor asking for 3/4 minus and a homeowner asking for road mix are asking for the same load.
On public works plans in Idaho the same material is written as crushed aggregate, called out as Type I or Type II. State highway work follows the ITD Standard Specifications, where Section 703.04 covers aggregate for untreated base and road mix and Section 703.11 covers granular subbase.
City, county and highway district work is usually written to the Idaho Standards for Public Works Construction, Section 802 for crushed aggregate and Section 801 for uncrushed. Those are how material is specified locally.
For drainage, drain rock is the clean angular choice, sold as washed rock or 3/4 clean. Rip rap armors creek banks, culvert outlets and pond edges against snowmelt and cloudburst runoff.
Natural Pea Gravel and river rock, listed in Idaho as round rock, finish patios and dry creek beds where a rounded look is wanted.
Ground Conditions Across Bonner County
Across the Panhandle forest and glacial ground, the uplands are volcanic ash over windblown loess with a dense fragipan below. That layer is close to watertight, so winter rain and snowmelt collect above it and sit near the surface through the wet months.
For a drive or pad, that means the base has to shed water rather than trap it. A clean drainage layer under the road mix gives the melt somewhere to go.
Erosion follows the same pattern. 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 it.
Rip rap on a cut slope or culvert outlet holds that ground in place.
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 runs from 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 about 24 inches in Coeur d'Alene and Kootenai County, with deeper figures used in the colder northern and higher valley towns.
The local building official sets footing depth.
Delivery Across Bonner County
Order online and a dump truck tips the load on site. You choose a quantity by the ton or by the yard, and each product page has a calculator if you want to size the load before you order.

Bulk delivery arrives as one tipped pile. Have the spot clear before the truck reaches it, since the load lands where it is tipped and stays there.
Choosing the Right Material
Bonner County shares its ground region with Kootenai, Shoshone and Boundary counties. All four sit on the same Panhandle forest and glacial ground, so the base and drainage reasoning carries across the county line.
The difference is where you build on that ground. On the forested uplands, ash over loess with a fragipan below holds melt near the surface, so drainage matters as much as base thickness.
On outwash ground, water disappears through gravel and cobbles instead of sitting.
Match the material to the ground you have. Road mix for a compacted base, drain rock where water has to move, and chips or Natural Pea Gravel for the surface.
