Bulk Aggregates for Pathways in White Swan, WA

Gravel and aggregate delivery in White Swan, WA runs on a long working season, and the smart move is timing your order ahead of the hard freeze. Washington Rock Supply sells bulk gravel, stone, sand and soil by the ton or the yard.

Start with 5/8 minus, the crushed surfacing top course this market builds paths and pads from. Locally that is CSTC, crushed rock with the fines left in.

Ground and Conditions in White Swan

Across the Columbia Basin, Yakima Valley and the channeled scablands, the ground is windblown loess over Columbia River basalt. The silt sits deep and sheds water rather than absorbing it.

Parts of the basin take only seven to nine inches of rain a year. When a cloudburst or a rapid thaw arrives, that dry silt sheds the water fast and short violent runoff cuts rills and gullies.

A path or drive built thin on that ground shows the failure early. The surface pumps, ruts form at the edges, and the fines wash out of the top course where runoff crosses it.

A compacted minus material holds up where a loose one does not. The fines in 5/8 minus bind the rock together so it packs hard and sheds water instead of soaking it up.

The 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, so plan around that window.

Winters here are cold and dry and summers hot and dry. The ground freezes properly on this side of the Cascades, unlike west of the mountains, and frost heave in an unbound base is worth designing for.

Materials for White Swan Projects

Fines and screenings do the work on paths and walkways here, because a walking surface has to knit together underfoot. The fine end of the minus range packs down tight and stays put.

Walkway Gravel is 1/4 minus, also called quarter minus or pathway gravel. It is the fine end of the minus range, so it packs down tight underfoot on garden paths, side yards and firm walking surfaces.

Stone Screenings is crusher dust, also called 3/8 minus or quarry dust. Use it for paver and flagstone bedding, joint filling and setting beds, since a minus product compacts rather than drains.

For paver joints and small drain runs where you want washed stone instead of a minus, 3/8" Crushed Stone is 3/8 clean. Wash the fines out and it drains.

5/8 Minus is the Washington default surfacing course. Driveways, parking pads, shed and shop slabs all take it, and it packs hard because the fines stay in.

1 1/4 Minus is the base course, CSBC. Larger top size and fewer fines than 5/8 minus, so it carries load and stays workable on soft wet ground under a drive or slab.
