Bulk Gravel Delivery to Othello, WA

Washington Rock Supply handles gravel and aggregate delivery in Othello, WA, from 5/8 minus for a packed driveway to washed stone for drainage. Adams County sits on windblown silt over basalt, and that ground shapes what you order.

Loess sheds water instead of soaking it up. A granular course that drains or compacts correctly matters more here than it would on heavier ground.

Ground and Conditions in Othello

Across the Columbia Basin, Yakima Valley and the channeled scablands, the ground is dry and loose for most of the year. Rain runs seven to nine inches in parts of the basin, then a thunderstorm or a rapid thaw lands all at once.

On silt with no cover, that water cuts rills and gullies fast. Wind moves the bare, dry surface too, and irrigation runoff carries soil with it.

A thin base course is where the trouble shows. Silt pumps up through a shallow layer of rock, the surface rutting and losing its shape under a truck or a trailer.

The fix is a structural course that carries load, placed under a compacted top course. On this ground the granular layers do the work that the silt cannot.

The working season runs long on either side of a hard winter. Once snow falls or the ground freezes, placing and compacting base material stops being practical.

Frost heave in an unbound base is real here, unlike west of the Cascades. The county or city building department sets the footing depth figure, and it runs deeper with elevation.

Materials for Othello Projects

Fines and screenings are the materials that finish paths, side yards and walkways in Othello. They pack tight underfoot because the crusher fines are left in, so the surface holds its shape instead of scattering.

Walkway Gravel, sold locally as 1/4 minus or pathway gravel, is the fine end of the minus range. It makes a firm walking surface for garden paths and side yards.

Stone Screenings, also called crusher dust or 3/8 minus, beds pavers and flagstone and fills joints. It is a minus product, so it compacts rather than drains.

For the driveway or pad those paths lead to, 5/8 Minus is the Washington default. It is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

The same material is specified locally as crushed surfacing top course, or CSTC.

Below it, 1 1/4 Minus, or crushed surfacing base course, is the structural course under a drive, parking area or slab. Its larger top size and fewer fines carry load and stay workable on soft, wet ground.

Where water needs to move instead of being held, Drain Rock, known as 7/8 clean or washed rock, keeps its voids for footing drains, French drains and infiltration trenches. Washed stone drains; a minus product compacts.
