3/8 Clean for Patios in Quinault, WA

Washington Rock Supply handles gravel and aggregate delivery in Quinault, WA, and the timing question comes first. This part of the Olympic Peninsula and the Pacific coast gets a short reliable dry window in mid to late summer, with a long wet season either side of it.

Plan a patio, walkway or shed pad into that dry stretch. 5/8 minus is the Washington surfacing course most patio bases start from.

Ground and Conditions in Quinault

Soil on this side of the state runs thin and stony over uplifted marine rock on the Olympic slopes. West-side valleys hold deep organic forest soil.

Along the outer coast and the bays you get sand, peat and tidal silt.

Paver and flagstone bedding fails on that ground in a known way. A thin base spread over soft, saturated soil pumps and shifts, so the flatwork above it moves with every wet season.

The fix is a base course that carries load over a drainage layer, not more bedding material.

Volume is the driver. The coast and the west-facing valleys take 100 to 170 inches of rain a year, so the question is never whether water arrives but where it goes.

Ground already saturated will not hold a base course without drainage under it.

Erosion follows the same pattern: sheer rainfall on steep, thin-soiled slopes, streambank scour in rivers that rise fast off the Olympics, and surf, drift and storm surge working the coast and bay shorelines.

The two-day soil stabilization rule for western Washington applies from October 1 through April 30. On the coast that is the practical limit on open grade.

Winters stay mild, so what stops work here is how wet it is, not how cold. Footing depth is set by the county or city building department, and western Washington figures run 12 to 18 inches.

Materials for Quinault Projects

Bedding under pavers and flatwork is a two-layer job, and the layers do different things. Start with 5/8 minus, also called crushed surfacing top course or CSTC.

The fines stay in, so it packs hard and sheds water instead of soaking it up.

Below that goes 1 1/4 minus, the crushed surfacing base course or CSBC. Larger top size and fewer fines mean it carries load and stays workable on soft wet ground.

For the setting bed itself, crusher dust, also called 3/8 minus or screenings, compacts rather than drains. It beds pavers and flagstones and fills joints.

Where you want a washed, fines-free stone in the joints or in a permeable setting bed, use 3/8 clean instead.

Firm walking surfaces beside the patio take 1/4 minus, also called quarter minus or pathway gravel. Rounded stone is a different family: Natural Pea Gravel and river rock are for beds, dog runs and splash pads, not for a compacted base.
