Do you deliver to Asotin County?

Yes. Washington Rock Supply delivers bulk gravel, stone, sand, soil and mulch across Asotin County, including Clarkston, Asotin and Anatone. You order online, choose a quantity by the ton or by the yard, and select a delivery date at checkout. A dump truck then tips the load on site.

What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone has angular faces and, in a minus product, the crusher fines left in, so it compacts and holds as a surface. Natural Pea Gravel is rounded and washed, so it will not compact and should be edged where it can wander. Use crushed stone for drives and pads, and Natural Pea Gravel for play areas and planting beds.

Should I order material by the ton or by the yard?

Both work, and the choice is yours at checkout. Each product page has a calculator you can use to size the load before you order. Quantities are ordered by the ton or by the yard, so pick whichever unit you are working in and let the calculator handle the rest.

Asotin County 5/8 Minus and Gravel Delivery, WA

Washington Rock Supply delivers gravel, stone and aggregate delivery in Asotin County, WA, ordered online and tipped on site by dump truck. If you are surfacing a drive, bedding a pipe or topping up a pad, the material you want is 5/8 minus.

That is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up. It is the same stone Washington quarries and contractors call crushed surfacing top course, or CSTC.

Materials Delivered in Asotin County

Material here is described the way Washington specifies it.

Contractors shorten those to CSBC and CSTC.

5/8 minus is the one to know first. It is specified as CSTC under Section 9-03.9(3) and ordered as 5/8 inch minus, and it is the surfacing course that goes on top of a 1 1/4 minus base.

For drainage, drain rock (also called 7/8 clean) is washed so it holds voids. Round stone is filed under round rock at Washington yards: Washington River Rock for dry creek beds and splash pads, and Large River Rock for swale and ditch armour.

Sand and soil round out an order. Washed Sand goes into concrete mixes, paver setting beds and pipe bedding.

Mason Sand is the mortar and stucco sand, often listed as plaster sand.

Fill Dirt raises grade and backfills over-excavations before a granular course goes down. Top Soil is screened and blended for lawn repair and new turf, and Shredded Mulch is the landscape bark sold locally as beauty bark.

Choosing the Right Material

Asotin County sits in the Palouse and the Blue Mountain foothills, and so does neighbouring Garfield County. The ground region is the same on both sides of the line: loess, and a lot of it.

That windblown silt is piled into rolling hills and reaches 250 feet thick in places. It is fine, deep and easily worked, and it moves easily too.

Basalt comes back to the surface in the canyons.

Because the ground is the same, the material choice is the same. A minus product compacts and holds a surface; a clean or washed product drains and keeps its voids.

Match that split to the job and the county line does not change anything.

Ground Conditions Across Asotin County

Start with where the water goes. Across the Palouse and the Blue Mountain foothills, the top inch of loess can thaw over soil still frozen below, and rain and snowmelt then run across the surface instead of soaking in.

Every slope becomes a drainage path. Anything built on a slope here needs runoff routed before it starts cutting, which is why drain rock and clean stone belong in the plan alongside the surfacing course.

Erosion follows the same pattern. Sheet and rill erosion of loess on long cultivated slopes is driven by rain falling on frozen soil, and about 40 percent of the original Palouse topsoil has been lost since farming began.

Timing matters as much as material. Eastern Washington's wet weather season runs October 1 through June 30.

The working season is long and dry through the summer and closes when the ground freezes, and the worst erosion risk is the thaw, not high summer.

Winters here are cold enough that the soil freezes to depth. Frost depth is set by the county or city building department, so confirm the local number before you plan footings.
