Bulk Material Delivery in Kamiah, ID
Idaho Rock Supply brings gravel and aggregate delivery in Kamiah, ID to drives, pads and building sites across Idaho County. The ground here is deep windblown loess over basalt, and that fine silt loam seals when it rains.
Road mix is the base that carries a drive or a shop floor over ground like that.
You order online, pick a quantity, and a dump truck tips the load on your site.
Materials for Kamiah Projects
Coarse stone does the heavy work on slope, swale and bank protection around Kamiah. Where runoff crosses a cut slope or a creek bank scours, the size of the rock decides whether it stays put.
Riprap is the largest option, and it is what armors creek banks, culvert outlets, canal banks and pond edges against snowmelt and cloudburst runoff. RipRap is angular, so it knits together instead of rolling.
Below that, Drain Rock is clean washed rock for french drains, foundation drains, drywells and downspout runs. It comes in 3/4 inch, 1 1/2 inch and 2 inch.
For a drive surface or pipe bedding, 3/4" Crushed Stone gives you an angular rock that stays where it is placed. 3/8 Chip is the finer size for pathways and a leveling course over compacted base.
Base material is where most builds start. Road mix, also called 3/4 minus, is crushed base with the fines left in so it locks up under a roller.
3/4 Road Mix goes under driveways, parking pads, shop floors and shed slabs.
Round rock is decorative rather than structural. Snake River Rock fills beds, borders and dry creek beds, and it rolls underfoot where chips do not.

Ground and Conditions in Kamiah
Sticky loess mud through the wet months is the real constraint on this ground. Hauling and compaction go best from late spring through fall, so a delivery date late in the season is easier on a soft site.
Across the Palouse hills and the Clearwater and Snake canyons, silt loam over loess seals under rain and sheds water rather than taking it in. Long slopes push that runoff onto roads, drives and yards, and water perches where the loess sits on basalt.
Sheet and rill erosion on cropped loess slopes in this part of the state is heavy, and canyon roads, culverts and creek banks scour under spring runoff and summer cloudbursts. That is why coarse stone on banks and swales matters here.
Winters run cold and wet with frequent freeze and thaw. No published frost figure was found for Idaho County, and the Idaho code leaves the frost line to the local jurisdiction, so the building official sets it.
Questions About Ordering in Kamiah
What stone should I use for drainage in Kamiah?
It depends on where the water goes. For french drains, foundation drains, drywells and downspout runs, use drain rock, which is clean washed rock in 3/4 inch, 1 1/2 inch or 2 inch.
For a creek bank, culvert outlet or swale, step up to riprap so the stone holds against snowmelt and cloudburst runoff.
What should I have ready when the truck arrives?
A clear spot for the pile and room for a dump truck to reach it. The truck tips the load in one pile, so the spot you choose is where the material stays.
Have the area free of vehicles and anything you do not want buried.
