Large Round Rock Delivery for Westport, WA

Washington Rock Supply brings gravel and aggregate delivery in Westport, WA to sites that spend most of the year wet. Along the outer coast, rain arrives faster than the ground can pass it.

Saturated ground will not hold a base course, so a drainage layer goes in first.

5/8 minus is the surfacing course that finishes the job. It packs hard and sheds water instead of soaking it up.

Materials for Westport Projects

Raising grade and building pads is the work this ground asks for first. Low, wet lots need fill before anything granular goes down, and the pad has to sit above the water that will not drain away.

Fill Dirt raises grade, backfills over-excavations and builds up low spots before a granular course goes down.

Gravel borrow in Section 9-03.14(1) is the granular structural fill, which is a different material.

1 1/4 Minus is the structural course under a drive, parking area or slab. It carries load and stays workable on soft wet ground.

Place it below a 5/8 minus top course.

5/8 Minus, also called crushed surfacing top course or CSTC, is the Washington default surfacing course. Crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

Drain Rock, also called 7/8 clean, is washed with no fines. It keeps its voids in footing drains, French drains and infiltration trenches.

That matters where a perched water table sits on till.

Driveway Gravel suits long rural drives, farm and forest approaches, and equipment parking.

Ground and Conditions in Westport

Across the Olympic Peninsula and the Pacific coast, the soil runs to sand, peat and tidal silt along the outer coast and the bays. Thin, stony soil sits over uplifted marine rock on the slopes.

Organic forest soil fills the west-side valleys.

Rainfall is the driver here, not cold. The coast and the west-facing valleys take 100 to 170 inches a year.

The question is never whether water arrives, but where it goes.

An under-built base fails on ground like this. Saturated soil will not hold a base course without a drainage layer under it.

Erosion works the same way, from sheer rainfall on steep, thin-soiled slopes and from surf, drift and storm surge on the shorelines.

The reliable dry window is short, in mid to late summer. The two-day soil stabilization rule for western Washington runs from October 1 through April 30.

On the coast that is the practical limit on open grade.

Winters stay mild, so the ground stays workable in temperature terms most of the year. What stops work is how wet it is, not how cold.

Frost depth is set by the county or city building department.
