Crushed Stone, Sand and Gravel in Brush Prairie, WA

Washington Rock Supply handles gravel and aggregate delivery in Brush Prairie, WA, for two kinds of buyers. Contractors grading a new pad and homeowners fixing a wet drive both order the same way, online, by the ton or the yard.

In this part of Clark County the conversation usually starts with 5/8 minus.

That material is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up. It is the Washington default surfacing course, and it is where most drives and parking pads finish.

Materials for Brush Prairie Projects

Grading and bed prep carry a lot of the work here. Before a drive, a slab or a garden bed can be finished, the ground under it has to be built up or cut down to the right level.

Fill Dirt raises grade, backfills over-excavations and builds up low spots before a granular course goes down. It is the material that gets a site to level, not the material that finishes it.

Top Soil goes on last. Local yards screen and blend it rather than selling native soil straight, so it is ready for lawn repair, new turf or grading out settlement around a foundation.

Garden Soil is a blend of screened soil and compost rather than plain topsoil. It suits raised beds, vegetable gardens and new planting beds where you want workable ground from the start.

Below the soil, the base courses do the structural work. 1 1/4 Minus, also called crushed surfacing base course or CSBC, sits under a drive or slab.

Its larger top size and fewer fines carry load and stay workable on soft ground.

The washed materials handle water. Drain Rock, sold as 7/8 clean or washed rock, has no fines, so it keeps its voids where water sits on tight soil.

Washed Sand covers concrete mixes, paver setting beds and pipe bedding.

Ground and Conditions in Brush Prairie

Water is the driver across this corner of the state. The Lower Columbia, Chehalis valley and Willapa Hills ground holds water rather than shedding it, so a pad or drive on it needs a free-draining course underneath.

That is what makes the minus and clean split matter here. A minus product like 5/8 minus holds moisture in its fines and packs into a firm surface.

A clean product like drain rock or 3/4 Crushed Stone lets water pass through.

The wet season runs October to April, and exposed unworked soil is limited to two days on the lower Columbia side. Plan grading around that window rather than fighting it.

Winters here are mild and wet, with only shallow frost. Ground that softens in Brush Prairie softens because it is full of water, not because it froze and thawed.

Frost depth is 12 inches in Cowlitz County and at Battle Ground, and the county or city building department sets the figure.
