Bark Mulch Delivery for Yakima, WA

You want gravel and aggregate delivery in Yakima, WA, and you want to know what to put in the beds. Washington Rock Supply delivers bulk material across the city and Yakima County, from 5/8 minus for a packed driveway surface to rounded stone for dry creek beds.

This is loess country, and that shapes what you order. Windblown silt sits deep here, so water sheds off bare ground instead of soaking in.

Delivery to Yakima and the Surrounding Area

You order online and pick a quantity by the ton or by the yard. Each product page has a calculator, so you can size the load before you check out.

At checkout you choose a delivery date. A dump truck then tips your material on site in one pile.

That is the whole of it, and it keeps the process simple whether you are in Yakima or out toward Selah, Wapato, Toppenish, Grandview or Sunnyside.

Materials for Yakima Projects

Beds, dry creek beds and ground cover are where most of this material goes. Rounded stone is what you want in a planting bed or a dry creek bed, because it reads as a river bottom rather than a construction pile.

• Washington River Rock for dry creek beds, downspout splash pads, planting beds and rain garden armour. Local yards file it under round rock.
• Large River Rock for swale and ditch armour, bank toes, culvert outfalls and feature beds where smaller stone would wash away.
• Natural Pea Gravel for play areas, dog runs and planting beds. It is rounded and washed, so it will not compact, and it should be edged where it can wander.
• Shredded Mulch for planting beds, tree rings and slope cover. Beauty bark is the local name for landscape bark.
• Top Soil for lawn repair, new turf and grading out settlement. Washington yards screen and blend it rather than selling native soil straight.

For a driveway, start with 1 1/4 minus as the structural course and top it with 5/8 minus. The minus products carry their crusher fines, so they pack hard and hold.

For a patio, bed pavers on crusher dust or on 3/8 clean where you want the joint to drain. For a drain, order drain rock, also called 7/8 clean, which is washed and keeps its voids.

Ground and Conditions in Yakima

The ground here is windblown loess over Columbia River basalt. Across the Columbia Basin, Yakima Valley and the channeled scablands, the Ice Age floods stripped that silt off in places and left the basalt bare.

Where flood gravel sits at the surface, water disappears straight down. Where the silt sits deep, a cloudburst or a rapid thaw sheds off it instead of soaking in, and short violent runoff cuts rills and gullies.

That matters to an under-built base. A drive or pad on silt needs a granular course that carries load, and 1 1/4 minus is the structural choice before a 5/8 minus surface goes down.

Winters here are cold and dry, and the ground freezes properly. Frost heave in an unbound base is something to design for, and the county or city building department sets the footing figure.

The working season is long either side of that winter. 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.
