Raising grade and building up pads is the work this ground asks for first. Low spots, over-excavated footings and settled ground all need fill before any granular course goes down.

Start with Fill Dirt, which is common borrow, and build the pad up to grade.

Under a slab, a drive or a parking area, 1 1/4 minus is the structural course. It is also called crushed surfacing base course, and the larger top size carries load on soft ground.

Place it below the surfacing. 1 1/4 Minus goes in first.

Top the base with 5/8 minus, the Washington default surfacing course, also called crushed surfacing top course. The fines stay in, so it packs hard and sheds water rather than soaking it up.

It suits driveways, parking pads and shed or shop slabs. 5/8 Minus is the surface.

Wet ground needs drainage before it needs more rock. Drain rock is washed, with no fines, so it keeps its voids and moves water away.

Use it for footing drains and French drains. Drain Rock fits that work.

Finish beds and paths with a minus that compacts tight underfoot. Crusher dust beds pavers and flagstone and fills joints, and 1/4 minus packs a firm walking surface for garden paths and side yards.

Order Stone Screenings for bedding and Walkway Gravel for paths.

Ground and Conditions in Wahkiacus

Windblown loess sits over Columbia River basalt across the Columbia Basin, Yakima Valley and the channeled scablands. Where the Ice Age floods ran, that silt was stripped off and the basalt left bare, and the floods dropped sand and gravel bars in the coulees.

Elsewhere the silt sits deep.

That ground is dry and loose through the season, then sheds water fast when a thunderstorm or a rapid thaw lands on it. An under-built base on silt pumps and loses its shape.

Get the fill and base course right and the surface holds.

Winter sets the schedule. Eastern Washington's wet weather season for erosion control runs October 1 through June 30, and once snow falls or the ground freezes, placing and compacting base material stops being practical.

The ground freezes properly here, unlike west of the Cascades. Frost heave in an unbound base is something to design for, and the county or city building department sets the footing depth.

Figures run deeper with elevation.
