Large Round Rock and Bulk Aggregates for Clayton, WA

If you are pricing gravel and aggregate delivery in Clayton, WA, the first question is usually which stone the job actually calls for. Washington Rock Supply sells it in bulk by the ton, and 5/8 minus is the surfacing course most drives and pads here start from.

This is glaciated country, thin stony soil over hard rock on the ridges with till and gravel filling the valleys. That mix decides what you order.

Materials for Clayton Projects

Water is the thing to plan around on a Clayton lot. Snowmelt leaves fast in spring, and ground that stays saturated needs somewhere for the water to go.

Washed stone is how you give it that path, because the crusher fines are taken out and the voids stay open.

Drainage Stone and Washed Rock

• Drain Rock, also called 7/8 clean or washed rock, for footing drains, French drains and curtain drains. No fines, so it drains instead of packing tight.
• 3/4" Crushed Stone for trench backfill, pipe surround and under-slab drainage. The washed counterpart to a minus product.
• #4 Crushed Stone, sold here as drywell rock, for drywells and heavy drainage.
• Large River Rock, also called 2 to 8 inch round or cobble, for culvert outfalls, ditch armour and downspout splash pads where a small stone would wash away in a winter storm.

Surfacing and Base Courses

A drive here is usually two courses. 1 1/4 Minus, the local name for crushed surfacing base course, goes down first and carries the load on soft spring ground.

5/8 Minus, or crushed surfacing top course, caps it and packs hard.

For a long rural approach or equipment parking, Driveway Gravel is the blended option Washington quarries sell alongside the graded courses.

Finer Stone, Sand and Soil

Stone Screenings, called crusher dust or 3/8 minus, bed pavers and flagstone. It compacts rather than drains, which is the opposite of what a drain trench wants.

Washed Sand goes into concrete mixes, paver setting beds and pipe bedding. Top Soil, screened and blended, handles lawn repair and grading out settlement.

Delivery to Clayton and the Surrounding Area

You order online and pick your quantity by the ton or by the yard. Each product page has a calculator if you want to size the load before checkout, and you choose your delivery date at checkout.

Washington Rock Supply delivers bulk aggregate to Clayton and the rest of Stevens County, including Colville, Chewelah, Kettle Falls, Loon Lake and Springdale. A dump truck tips the load as one pile at the address you give.

Pick a date when the ground is workable. A pile set on soft spring ground is harder to move than one dropped onto a firm surface.

Ground and Conditions in Clayton

Across the Okanogan Highlands and the northeast corner, the working season is short. Most of the year's water arrives as snow and leaves over a few weeks in spring, and the higher and further north the site, the tighter that window gets.

Valley floors of outwash gravel drain quickly. Till and lake silt do not, and snowmelt sitting on top of ground that is still frozen below is what turns a build site soft.

That is the argument for a washed drainage layer under anything that has to stay firm.

Spring runoff scours ditches, culverts and gravel roads during breakup, and bare burned slopes shed soil and rock. Armour those spots with larger rounded stone rather than a minus product.

Frost is a real factor in the coldest corner of the state. Okanogan County publishes a frost depth of 24 inches, and the county or city building department sets the figure that applies to your site.
