Bulk Material Delivery in Hay, WA

Washington Rock Supply handles gravel and aggregate delivery in Hay, WA, and the ground here shapes what you order. The Palouse hills are built from deep windblown silt that thaws over frozen soil in late winter, so water runs across the surface instead of soaking in.

Start with 5/8 minus for a drive or pad, then size the load on the product page calculator before you check out.

Materials for Hay Projects

Washed stone is the material that keeps water moving on this ground. With the fines taken out, the voids stay open, so a trench or a drywell can actually take water instead of silting shut.

Drain Rock, also called 7/8 clean, is washed rock for footing drains, French drains and curtain drains. It keeps its voids where a perched water table sits on the silt.

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

3/8" Crushed Stone is 3/8 clean, a fines-free stone for paver joints, permeable paver setting beds and small drain runs.

For downspout runs and drywells, #4 Crushed Stone is the coarse washed size. It is also called number 4 stone or drywell rock.

Then come the minus materials, where the fines stay in and the rock packs hard. 5/8 Minus is the Washington default surfacing course, also called crushed surfacing top course, for driveways, parking pads and shed slabs.

1 1/4 Minus, or crushed surfacing base course, sits below it as the structural course on soft wet ground.

Delivery to Hay and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then tips the load on your site in one pile.

Delivery covers Hay and the rest of Whitman County, including Pullman, Colfax, Palouse, Tekoa and St. John.

Whether the site is in town or out on a farm approach, the load arrives the same way.

Each product page has a calculator, so you can size the load before you order. Bulk material is sold by weight or volume, not by the bag.

Ground and Conditions in Hay

Eastern Washington's wet weather season runs October 1 through June 30. The working season is long and dry through the summer and closes when the ground freezes.

The worst erosion risk is not high summer, it is the thaw. When the top inch of loess thaws over frozen soil below, rain and snowmelt run across the surface instead of soaking in.

That makes every slope a drainage path, and anything built on a slope here needs runoff routed before it starts cutting. Sheet and rill erosion of loess on long slopes is what moves the ground.

So plan a delivery while the ground is open and workable. A washed drainage layer under a compacted surface course is how a drive or pad handles the thaw instead of fighting it.

Frost depth is set by the county or city building department, so confirm the local number before you plan footings.
