Washington Rock Supply brings gravel and aggregate delivery in Pullman, WA to homeowners, farms and contractors working on Whitman County ground. You order online by the ton or the yard, and a dump truck tips the load on site.

Much of what leaves for Pullman is 5/8 minus, the crushed rock this state calls crushed surfacing top course, with the fines left in so it packs hard and sheds water instead of soaking it up.

Pullman sits on deep loess, the windblown silt that built the rolling hills around town, and that fine ground shapes what a driveway, pad or trench here actually needs.

Materials for Pullman Projects

Start with the surfacing course. 5/8 Minus, sold locally as 5/8 inch minus, is the Washington default top course for driveways, parking pads and shed or shop slabs.

The crusher fines stay in the mix, so it compacts into a tight surface rather than staying loose underfoot.

Under that top course goes the structural layer. 1 1/4 Minus, also called crushed surfacing base course, has a larger top size and fewer fines, so it carries load and stays workable where the ground runs soft and wet.

It sits below the 5/8 minus, not in place of it.

Where water needs somewhere to go, use washed stone. Drain Rock, known here as 7/8 clean or washed rock, has no fines and keeps its voids open in footing drains, French drains and infiltration trenches.

For a firm walking surface, Walkway Gravel (1/4 minus) packs down tight on garden paths and side yards. Bed pavers and flagstone on Stone Screenings, also called crusher dust or 3/8 minus, which compacts rather than drains.

Long rural drives and equipment parking often call for Driveway Gravel, the surfacing blend Washington quarries sell alongside the graded courses.

Round the order out with sand and soil: Washed Sand for concrete mixes and paver setting beds, Mason Sand for mortar, stucco and joint sweeping, Top Soil for lawn repair and grading out settlement, and Shredded Mulch, the product listed here under its Washington trade name, beauty bark.

Ground and Conditions in Pullman

Across the Palouse and the Blue Mountain foothills, water is the driver. When the top inch of loess thaws over soil still frozen below, rain and snowmelt run across the surface instead of soaking in, and every slope turns into a drainage path.

Anything built on a slope needs that runoff routed before it starts cutting.

The silt itself is fine, deep and easily worked, and it moves easily too. Sheet and rill erosion of loess on long slopes is the pattern in this part of the state, and the risk peaks not in high summer but at the thaw.

That is why a fines-bearing course such as 5/8 minus earns its place on a Pullman drive: it knits together and holds a surface where loose clean stone would not.

Timing matters as much as material. Eastern Washington's wet weather season runs October 1 through June 30, so the working season is long and dry through summer and closes when the ground freezes.

Build the granular work into that dry window and let washed stone handle the water that arrives anyway.

Cold winters freeze the soil to depth here, and a late-winter pattern of warm rain on frozen or part-thawed ground is the most damaging condition in this part of the state.

Frost depth is set by the county or city building department, and the published figures nearby differ, so confirm the local number rather than assuming one.
