Buy 1 1/4 Minus in Edwall, WA

Washington Rock Supply handles gravel and aggregate delivery in Edwall, WA for two kinds of buyers: contractors building drives, pads and slabs, and homeowners patching a lane or setting a shed. Both usually start with 5/8 minus, the crushed surfacing top course that packs hard and sheds water.

Edwall sits on windblown loess over Columbia River basalt, and that ground shapes what you order. The silt is fine and sheds water rather than soaking it up, so a surfacing course has to be built to move water off, not into, the ground beneath it.

Materials for Edwall Projects

Base and driveway surfacing is where most Edwall jobs begin, and the two minus courses do the structural work. 1 1/4 Minus, also called crushed surfacing base course, or CSBC, is the larger course placed below the top layer.

Its bigger top size and lower fines content let it carry load and stay workable on soft, wet ground.

5/8 Minus, the crushed surfacing top course known locally as CSTC, is the Washington default surfacing layer. The crusher fines are left in, so it compacts tight and sheds water instead of soaking it up.

It suits driveways, parking pads and shed or shop slabs.

For long rural approaches and equipment parking, Driveway Gravel is sold as a blend alongside the graded surfacing courses. Where a path or side yard needs a firm surface underfoot, Walkway Gravel, or 1/4 minus, packs down tight because it sits at the fine end of the minus range.

Washed stone is the other half of the split, and it drains rather than compacts. Drain Rock, also called 7/8 clean, keeps its voids with no fines to fill them, which is what a footing drain or French drain needs where water sits on till.

For trench backfill, pipe surround and under-slab drainage, 3/4" Crushed Stone is the washed counterpart to a minus product. Sand, soil and decorative stone round out an order: Washed Sand for concrete and bedding, Top Soil for lawn repair, and Washington River Rock for dry creek beds and splash pads.

Ground and Conditions in Edwall

Across the Columbia Basin, Yakima Valley and the channeled scablands, the water story runs both ways. Parts of the basin take only a handful of inches of rain a year, so the ground stays dry and loose, and then a thunderstorm or a rapid thaw arrives all at once.

When that happens, the silt sheds water rather than absorbing it, and runoff cuts rills and gullies in bare loess. Wind off dry, exposed silt moves soil too.

A drive or pad that leaves fines sitting on the surface gives that water and wind an easy place to work.

Where flood gravel sits at the surface, water disappears straight down instead. That is the opposite problem, and it changes what you put under a slab.

A washed stone layer drains; a minus course compacts and holds. Getting the split right is the difference between a surface that stays put and one that pumps.

Timing matters here as much as material. The wet weather season for erosion control in eastern Washington runs October 1 through June 30.

Once snow falls or the ground freezes, placing and compacting base material stops being practical.

Winters in this part of the state are cold and dry, and the ground freezes properly, 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 figure.

It runs deeper with elevation.
