Gravel, Stone and Soil for Jefferson County, WA

If you are building a driveway, setting a patio base, or running drainage on the Olympic Peninsula and the Pacific coast, you need gravel, stone and aggregate delivery in Jefferson County, WA. Washington Rock Supply sells it in bulk and delivers it to your site.

Start with 5/8 minus. It is the default surfacing course in this part of Washington, crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

Materials delivered in Jefferson County

Material here splits two ways: minus products hold their fines and compact, clean products are washed and drain. Knowing which side of that line a job sits on settles most of the choice.

Contractors shorten it to CSTC and order it as 5/8 minus.

It is the course that takes the traffic and sheds the rain.

Below it goes 1 1/4 Minus, the base course grading with a 1 1/4 inch top size. It carries load and stays workable on soft, wet ground where a finer material would pump.

Sand and soil round out an order. Washed Sand goes into concrete mixes, paver setting beds and pipe bedding, washed so silt does not sit in the mix.

Top Soil is screened and blended for lawn repair, new turf and grading out settlement.

Ground conditions across Jefferson County

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

Soil across this ground region runs thin and stony over uplifted marine rock on the Olympic slopes, with deep organic forest soil in the west-side valleys. Sand, peat and tidal silt sit along the outer coast and the bays.

Ground that is already saturated will not hold a base course without a drainage layer under it. That is where Drain Rock and 3/4" Crushed Stone come in, washed stone that keeps its voids instead of filling with fines.

Erosion here comes from sheer rainfall on steep, thin-soiled slopes, from streambank scour in rivers that rise fast off the Olympics, and from surf, drift and storm surge on the outer coast and the bay shorelines. RipRap and Large River Rock armour those edges.

The reliable dry window is mid to late summer, with a long wet season either side of it. The two-day soil stabilization rule for western Washington runs from October 1 through April 30, and on the coast that is the practical limit on open grade.

The ocean keeps winters mild and hard freezes short, so the ground stays workable in temperature terms most of the year. What stops work here is how wet it is, not how cold.

Frost depth is set by the county or city building department, with published western Washington figures running 12 to 18 inches.

Choosing the right material

Clallam County shares this ground region: thin, stony soil over uplifted marine rock on the Olympic slopes, deep organic forest soil in the west-side valleys, and sand, peat and tidal silt along the outer coast and the bays. The base and drainage choice is the same one you make here.

Grays Harbor County spans more than one zone. Its ground also takes in the Lower Columbia, the Chehalis valley and the Willapa Hills, so parts of it sit on different material than the Olympic Peninsula and the Pacific coast side.

Within Jefferson County, the split is simpler. Minus products compact and hold a surface; clean and washed products drain.

A drive or pad takes a compacting course. A drain, drywell or saturated slope takes washed stone.
