Railroad Ballast, Stone and Soil Delivery in Sunnyside, WA

Washington Rock Supply handles gravel and aggregate delivery in Sunnyside, WA. Start with 5/8 minus, the crushed surfacing top course this side of the state builds drives and pads from.

Across the Columbia Basin, Yakima Valley and the channeled scablands, the ground runs dry and loose, then sheds a cloudburst instead of soaking it in. Washed stone answers that.

Materials for Sunnyside Projects

Water is the whole problem here. Rain arrives in short bursts, and silt ground sheds it fast.

Washed stone gives that water somewhere to go.

Drain Rock, also called 7/8 clean, has no fines left in it. The voids stay open, so a footing drain or French drain keeps working where a perched water table sits.

3/4" Crushed Stone is the washed counterpart to a minus product. Use it for trench backfill, pipe surround and under-slab drainage, because it drains instead of compacting.

#4 Crushed Stone is the coarse, open size for drywells and heavy drainage.

4 as the alternative for gravel backfill for drywells.

3/8" Crushed Stone, sold as 3/8 clean, suits downspout runs, paver joints and small drain runs. Same washed, fines-free idea at a smaller size.

For a surface that has to hold up, 5/8 Minus packs hard because the crusher fines stay in the mix. 1 1/4 Minus goes underneath it as the structural course, and its larger top size and fewer fines keep it workable on soft, wet ground.

Ground and Conditions in Sunnyside

Windblown loess sits over Columbia River basalt across this part of the state. Where the Ice Age floods ran, that silt was stripped off and the basalt left bare, and the floods dropped sand and gravel bars behind them.

Where flood gravel reaches the surface, water disappears straight down. Where deep silt remains, it grows wheat, hops, orchards and vines under irrigation, and it sheds a cloudburst rather than absorbing it.

Wind off bare, dry silt moves soil, and short violent runoff cuts rills and gullies when a storm lands on ground with no cover. Irrigation runoff moves soil too, so plan drainage before you plan surface.

The working season runs long on either side of a hard 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.

Winters here are cold and dry and summers hot and dry, so the ground freezes properly, unlike west of the Cascades. Frost heave in an unbound base is worth designing for, and the county or city building department sets the footing depth figure.
