Bulk Aggregate Delivery Across Kootenai County, ID

Ordering gravel, stone and aggregate delivery in Kootenai County, ID starts with one question: what does the job actually need under it? For most drives, shop pads and shed slabs the answer is road mix, the crushed base with the fines left in that locks up under a roller.

Idaho Rock Supply sells that base and the rest of the load online, by the ton or the yard, and a dump truck tips it on site. This is Panhandle forest and glacial ground, so the material you pick has to suit the soil it lands on.

Pick a delivery date at checkout and a dump truck brings the material to the address. The truck tips the load in one pile on site, so the spot you choose is the spot the pile lands.

Delivery covers Coeur d'Alene, Post Falls, Hayden, Rathdrum, Spirit Lake, Athol, Harrison, Worley, Bayview, Cataldo and Medimont. Rural approaches and in-town lots are both served the same way.

Materials delivered in Kootenai County

Start with the project, not the product name. A driveway, a patio and a drain each want a different load.

Road mix carries the most weight on base work. Idaho yards call it road mix, 3/4 road mix or crushed base, and a contractor asking for 3/4 minus is asking for the same load.

On public works plans it is written as crushed aggregate, Type I or Type II, under Section 802, while state highway work follows the ITD Standard Specifications, where Section 703.04 covers Aggregate for Untreated Base, Treated Base and Road Mix and Section 703.11 covers granular subbase.

For drainage, drain rock is the clean washed rock used in french drains, foundation drains, drywells and downspout runs. Where a finer walkable surface is wanted, walkway gravel and stone screenings bed pavers and surface paths.

For fill and planting, fill dirt brings a low spot up before a base course goes on, and garden soil fills raised beds where the native ground is too thin or too stony to plant into.

Sand work runs to washed sand for bedding under pavers and slabs and mason sand for brick, block and paver joints.

Ground conditions across Kootenai 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.

Under-built base is what fails on ground like that. A drive or pad laid on soft, saturated subgrade moves, so the subgrade has to be brought up with pit run or fill dirt before road mix goes on top.

A few miles away, the flood-laid sand, gravel and cobbles of the Rathdrum Prairie drain so fast that water disappears through them. On that ground a clean drainage layer matters more than holding moisture back.

Erosion follows the same split. 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 armors creek banks, culvert outlets and pond edges against that runoff.

Wet ground from late fall through spring limits work here more than cold does, so base and paver work waits for the ground to drain. Midsummer into early fall is the dependable window.

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, and the local building official sets footing depth.

Choosing the right material

Bonner County, Shoshone County and Benewah County all sit on the same Panhandle forest and glacial ground as Kootenai County. That means the same ash over loess, the same fragipan and the same outwash gravel, so the base and drainage choices do not change when a job crosses a county line.

What changes is where you build on that ground. On the uplands, water sits above the fragipan and the subgrade needs bringing up before a base course.

On the outwash, water drops away and a clean drainage layer does the work.
