5/8 Minus, Sand and Gravel Delivery in Pend Oreille County, WA
Washington Rock Supply handles gravel, stone and aggregate delivery in Pend Oreille County, WA. The season here is short, so most base and drive work fits between spring breakup and the autumn freeze.
5/8 minus is the surfacing course most of that work starts from. It is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

5/8 Minus is the Washington default surfacing course. Contractors and quarries also call it crushed surfacing top course, or CSTC, and order it as 5/8 inch minus.
It goes on driveways, parking pads, and shed and shop slabs. The fines are left in the blend, so it compacts into a tight surface rather than staying loose underfoot.
That section sets two gradings: base course with a 1 1/4 inch top size, and top course with a 5/8 inch top size.
1 1/4 Minus, or CSBC, is the structural course under a drive, parking area or slab. It sits below a 5/8 minus top course and carries load on soft spring ground.
Drain Rock, also sold as 7/8 clean, is washed with no fines. It keeps its voids in footing drains, French drains and infiltration trenches where water perches on till.
Driveway Gravel suits long rural drives, farm and forest approaches, and equipment parking. Walkway Gravel, or 1/4 minus, packs down tight for garden paths and side yards.
Stone Screenings, also called crusher dust or 3/8 minus, bed pavers and flagstone and fill joints. It compacts rather than drains.
3/4" Crushed Stone is the washed counterpart for trench backfill and pipe surround.
Round and decorative stone covers the rest of the yard. Natural Pea Gravel suits play areas and planting beds, Washington River Rock builds dry creek beds and splash pads, and RipRap armours shorelines, streambanks and culvert outfalls.
Choosing the Right Material
Stevens County sits in the same Okanogan Highlands and northeast corner ground as Pend Oreille County. The soil, the snowmelt pattern and the short working season are the same, so the base and drainage choices carry over unchanged.
Spokane County is different. Its ground spans the Spokane and Selkirk foothills and reaches into the Palouse and the Blue Mountain foothills, so it covers more than one zone.
That wider range means ground there can be finer and less stony than the glaciated ridges here. Where silt and clay hold water, drainage rock and washed stone matter more than they do on a gravel valley floor.
On this county's thin stony soil over granite and gneiss, a minus product compacts well and a clean stone drains well. Match the material to whether you need the surface to hold or to shed water.
Ground Conditions Across Pend Oreille County
Across the Okanogan Highlands and the northeast corner, the ground is glaciated mountain country. Thin stony soil sits over granite, gneiss and metamorphic rock on the ridges, with till, outwash gravel and lake silt filling the valleys.
That mix decides how a base behaves. Gravel valley floors drain quickly, while till and lake silt hold water and stay soft well into spring.
Most of the year's water arrives as snow and leaves over a few weeks in spring. The valley soils saturate while the ground below them is still frozen, so a thin base shows its failure mode right there.
The fix is a granular course that carries load and drains instead of trapping water. 1 1/4 minus under a 5/8 minus top course does that work on a drive or pad.
Spring runoff scours ditches, culverts and gravel roads during breakup, and cuts streambanks in the valley rivers. Riprap and large round rock armour those edges where moving water is the problem.
Frost heave and soft spring ground govern any unbound base in the coldest corner of the state. Long winters and a slow breakup mean the working window is shorter the higher and further north the site.
Eastern Washington's wet weather season for erosion control runs October 1 through June 30. Bare burned slopes shed soil and rock after the region's wildfire seasons, so cover them before that window opens.
