5/8 Minus, Stone and Soil Delivery in Rockford, WA

Washington Rock Supply brings gravel and aggregate delivery in Rockford, WA, and the ground here decides how a drive gets built. This part of the Palouse is deep windblown silt, fine and easily worked, and it moves when water gets into it.

That is why 5/8 minus, the crushed surfacing top course local yards call CSTC, is the usual starting point. The fines stay in the blend, so it packs hard and sheds water instead of soaking it up.

Materials for Rockford Projects

Water is the thing to plan around on this side of the state. When the top inch of ground thaws over soil still frozen below, meltwater runs across the surface instead of soaking in.

Washed stone gives that water somewhere to go.

Drain Rock, also sold as 7/8 clean, is washed with no fines left in it. It keeps its voids, which is what a footing drain or French drain needs where water sits on top of tight ground.

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

#4 Crushed Stone, often called drywell rock, is the coarse open grade for drywells and heavy drainage. #8 Crushed Stone is the smaller washed stone for downspout runs and fine drainage.

Where a surface has to carry load, a minus product does the work. 1 1/4 Minus, the crushed surfacing base course or CSBC, sits below a 5/8 minus top course and carries traffic on soft wet ground.

For firm walking surfaces, Walkway Gravel is the fine end of the minus range and packs down tight underfoot. Stone Screenings, or crusher dust, beds pavers and flagstone and compacts rather than drains.

Delivery to Rockford and the Surrounding Area

Washington Rock Supply delivers bulk material to Rockford and the rest of Spokane County, including Spokane, Cheney, Liberty Lake, Airway Heights and Mead. You order on the site and a dump truck brings the load to your site.

Quantities are ordered by the ton or by the yard. Each product page has a calculator if you want to size a load before you order, and you pick your delivery date at checkout.

The truck tips the load in one pile where it can reach. Plan for that pile to land somewhere it will not block the work you are about to do.

Ground and Conditions in Rockford

The working season here runs long and dry through the summer and closes when the ground freezes. Eastern Washington's wet weather season runs October 1 through June 30, so timing a delivery matters more than it does in a milder climate.

The worst erosion risk is not high summer. It is the thaw, when rain falls on frozen or part-thawed ground and every slope turns into a drainage path.

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

Loess is fine, deep and easily worked, and it moves easily too. That is the argument for a compacting minus product on a drive rather than a clean stone that lets water straight through.

Frost depth is set by the county or city building department. The published figure is 24 inches at Spokane, just north of here, so confirm the number that applies to your job.

Questions About Gravel in Rockford

Do you deliver 5/8 minus to Rockford, WA?

Yes. Washington Rock Supply delivers 5/8 minus and other bulk aggregates to Rockford and the surrounding parts of Spokane County.

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

What gravel is best for a driveway in Rockford?

Start with 1 1/4 Minus as the structural course and top it with 5/8 Minus. The 1 1/4 minus carries load and stays workable on soft wet ground, and the 5/8 minus packs hard and sheds water.

That pairing suits the deep silt here, where a clean stone would let water pass through instead of holding a surface.
