Order Road Mix and Crushed Stone in Clearwater County, ID
Idaho Rock Supply handles gravel, stone and aggregate delivery in Clearwater County, ID. The ground here is deep windblown loess, silt loam over basalt, and it seals under rain instead of taking water in.
That single fact shapes every base decision on a drive, a pad or a shop floor.
Road mix is the local name for the crushed base with the fines left in, and it is where most base work starts. Order online by the ton or the yard and a dump truck tips the load on site.
Delivery across Clearwater County
You order online, size the load by the ton or by the yard, and pick a delivery date at checkout. Each product page has a calculator if you want to check a quantity before you commit.
A dump truck tips the load in one pile on site. That is the whole delivery, so the spot you choose is the spot the material stays until you move it with your own equipment.
Idaho Rock Supply delivers to Orofino, Pierce, Weippe, Ahsahka, Lenore and the rural addresses between them. Long rural approaches are common here, and a load of road mix or driveway gravel for a drive that climbs away from the river is a normal order.
Materials delivered in Clearwater County
Start with the project type. A driveway, a patio and a drain each want a different material, and the names below are the ones used in Idaho.
Road mix is the workhorse. State highway work describes it under the ITD Standard Specifications, Section 703.04, Aggregate for Untreated Base, Treated Base and Road Mix, which is where the 3/4 inch minus gradation comes from.
City, county and highway district jobs are usually written to the Idaho Standards for Public Works Construction, whose Section 802 covers crushed aggregate in Type I and Type II. Contractors ordering 3/4 minus and homeowners ordering road mix are asking for the same load.
Ground conditions across Clearwater County
The ground across the Palouse hills and the Clearwater and Snake canyons is deep windblown loess, in places tens of feet thick, lying on Columbia River basalt. Silt loam over loess seals under rain and sheds water instead of taking it in.
That means long slopes push runoff onto roads, drives and yards, and water perches where the loess sits on basalt. An under-built base on this ground pumps and ruts, so the base course is the part worth getting right.
Sheet and rill erosion on cropped loess slopes in this part of the state is among the heaviest anywhere in the country. Canyon roads, culverts and creek banks scour under spring runoff and summer cloudbursts, which is where rip rap earns its place.
Sticky loess mud through the wet months is the real constraint on hauling and compaction. Work goes best from late spring through fall, and the canyon towns get a longer window than the prairie above them.
Winters here are cold and wet with frequent freeze and thaw cycles. No frost depth was published for Clearwater County, and Idaho code leaves the frost line to the local jurisdiction, so the building official sets it.
Choosing the right material
Nez Perce County and Latah County sit on the same ground as Clearwater County, the same deep loess over basalt with the same canyon rimrock and the same perched water. The base and drainage choices do not change from one to the next.
Idaho County spans more than one zone. It carries the Palouse hills and the Clearwater and Snake canyons ground plus the Central Idaho mountains and high valleys, so its stony mountain ground and thinner soils are a different situation from the loess here.
On thinner mountain ground a screened Top Soil goes further and drainage has less fines to clog it.
Match the material to the job. 3/4 Road Mix is the compacted base under a drive, pad or slab, with Pit Run below it as sub base or fill where grade has to come up first.
For a patio, set the pavers on Washed Sand or Stone Screenings over that compacted base. 3/8 Chip tops a path, while 3/8" Natural Pea Gravel is round and rolls underfoot, so it suits play areas and dog runs more than a slope.
For drainage, Drain Rock is the clean angular choice for a french drain, a drywell or a drainfield. Snake River Rock and Large River Rock are round and decorative, for dry creek beds and borders rather than for moving water underground.
