Order 5/8 Minus and Crushed Stone in Wahkiakum County, WA
Washington Rock Supply sells gravel, stone and aggregate delivery in Wahkiakum County, WA by the ton or the yard, ordered online. Start with 5/8 minus, the crushed surfacing top course this part of Washington builds drives and pads on.
River terrace silt and gravel along the Lower Columbia, Chehalis valley and the Willapa Hills holds water instead of shedding it, so a free-draining course underneath does the work.

5/8 Minus is the Washington default surfacing course: crushed rock with the fines left in.
Order it for driveways, parking pads, shed slabs and any surface that has to pack hard. Under it, place 1 1/4 Minus, the base course grading at a 1 1/4 inch top size, shortened to CSBC.
Washed stone, sand and soil
- RipRap for shoreline, streambank, culvert outfall and cut-slope protection.
- Railroad Ballast for rail spurs, yard track and heavy equipment pads.
- Natural Pea Gravel and Washington River Rock for play areas, dog runs, planting beds, dry creek beds and downspout splash pads. Rounded and washed, so it will not compact.
- Large River Rock for swale and ditch armour, bank toes and culvert outfalls where a smaller stone would be carried off in a winter storm.
- Mason Sand for mortar, stucco and plaster, and Washed Sand for concrete mixes, paver setting beds and pipe bedding.
- Top Soil for lawn repair and new turf, Fill Dirt for raising grade, and Shredded Mulch, sold here as beauty bark, for planting beds.
Delivery across Wahkiakum County
Order online, enter your quantity by the ton or by the yard, size the load on the product page calculator, and pick a delivery date at checkout. A dump truck arrives and tips the material in one pile on site.
Have the drop area clear and reachable before the truck arrives. Deliveries cover Cathlamet, Rosburg, Grays River and Skamokawa, along with the surrounding rural addresses.
Bulk loads arrive loose and unplaced. Nothing is spread and nothing is spotted for you, so choose the pile location before the truck reaches the property.
Ground conditions across Wahkiakum County
Water is the driver here. Valley flooding and slow-draining silt are the pattern across the Lower Columbia, Chehalis valley and the Willapa Hills, and fine-grained terrace and hill soils hold water rather than shedding it.
That is why a pad or drive needs a free-draining course under it. Drain Rock and 3/4" Crushed Stone keep their voids and let water move instead of sitting against the base.
Winters stay mild and wet, with only shallow frost. Ground here softens because it is full of water, not because it has frozen and thawed.
Frost depth figures are set by the county or city building department.
The wet season runs October to April, with two days the limit on exposed unworked soil. Plan grading in the river valleys around the winter flood season as much as around the rain.
Long rain also brings shallow slides in the weathered hill soils, riverbank scour and channel movement, and sediment washing off cleared ground. RipRap and Large River Rock armour the places where moving water does the damage.
Choosing the right material
Pacific County sits on the Olympic Peninsula and the Pacific coast, where thin, stony soil over uplifted marine rock, deep organic forest soil in the west-side valleys, and sand, peat and tidal silt along the outer coast and the bays change what a base has to do.
Peat and tidal silt are the difference. Where ground is organic and soft, a structural course such as 1 1/4 Minus carries the load that a fines-heavy surfacing course cannot on its own.
Cowlitz and Lewis counties share this ground region, the Lower Columbia, Chehalis valley and the Willapa Hills, so the same base and drainage choices apply there.
