Order Gravel, Stone and Soil in Zillah, WA

Washington Rock Supply handles gravel and aggregate delivery in Zillah, WA, from 5/8 minus to washed sand. If you are building a drive, a pad or a bed, the material choice starts with what the ground under it does.

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

Delivery to Zillah and the Surrounding Area

You order online and pick a quantity by the ton or by the yard. Each product page has a calculator if you want to size the load before checkout, and you choose a delivery date there.

A dump truck tips the load on site in one pile. Zillah sits in Yakima County, and delivery reaches the town and the surrounding area, including Yakima, Sunnyside, Grandview, Toppenish and Selah.

Materials for Zillah Projects

Decorative rock carries a lot of the work here, and it starts with the beds. Washington River Rock is rounded stone for dry creek beds, downspout splash pads and planting beds.

Its shape lets water move along the bed instead of pooling against the house.

Large River Rock is the bigger rounded stone, from 2 to 8 inch round. It armours swales, ditch lines and culvert outfalls where a smaller stone would be carried off in a winter storm.

For ground cover that stays put underfoot, Natural Pea Gravel is rounded and washed, so it will not compact. It suits play areas, dog runs and pipe bedding, and it should be edged where it can wander.

Shredded Mulch covers tree rings, planting beds and slopes. Beauty bark is the local trade name for landscape bark, and it is the name this product is listed under.

Under all of that sit the structural materials. 1 1/4 Minus, also called CSBC, is the base course below a 5/8 minus top course.

It carries load and stays workable on soft wet ground.

Ground and Conditions in Zillah

Across the Columbia Basin, Yakima Valley and the channeled scablands, the ground is windblown loess over Columbia River basalt. Where the Ice Age floods ran, that silt was stripped off and the basalt left bare.

That matters for a base. Loess sheds water rather than absorbing it, so an under-built drive takes the runoff straight through the surface course and moves.

Water arrives in two modes here. Parts of the basin take only seven to nine inches of rain a year, and then a thunderstorm or a rapid thaw lands on dry, loose silt all at once.

Wind off bare, dry silt moves soil, and short violent runoff cuts rills and gullies into loess with no cover on it. Irrigation runoff moves soil too.

Winters are cold and dry, and 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 figure.

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