Bulk Aggregates for Pathways in Rock Island, WA

Washington Rock Supply handles gravel and aggregate delivery in Rock Island, WA for two kinds of buyers: contractors working a schedule and homeowners fixing a path or drive on a weekend.

This is channeled scabland country, where flood gravel sits at the surface and water drops straight through. That changes what you want underfoot, and 5/8 minus is where most paths and drives start.

Ground and Conditions in Rock Island

Across the Columbia Basin, Yakima Valley and the channeled scablands, the ground is windblown loess over basalt. Where the Ice Age floods ran, the loess was stripped and the basalt left bare.

Rainfall here is scarce, then arrives all at once. The silt sheds water instead of absorbing it, so a thin base fails fast: ruts, potholes, and stone pushed out of the track.

Wind off bare, dry silt moves soil, and short violent runoff cuts rills and gullies. A firm, bound surface is the practical answer.

The working season runs long on either side of a hard winter. The state wet weather season for erosion control is October 1 through June 30, so plan placement around frozen ground and snow.

Ground freezes properly here, unlike west of the Cascades, and frost heave in an unbound base is something to design for. The county or city building department sets footing depth, and it runs deeper with elevation.

Materials for Rock Island Projects

The fine end of the minus range does the most for pathways, side yards and firm walking surfaces. These products pack down tight underfoot, which is exactly what a scabland path needs.

Fines and Screenings for Paths and Walkways

Walkway Gravel, also called 1/4 minus, is the tightest packing of the group. It makes garden paths and side yards that stay firm in the wet.

Stone Screenings, or crusher dust, is a minus product that compacts rather than drains. It beds pavers and flagstone and fills joints.

5/8 Minus, called crushed surfacing top course or CSTC, is the Washington default surfacing course. The fines stay in, so it packs hard and sheds water instead of soaking it up.

Supporting Materials

1 1/4 Minus, or crushed surfacing base course, is the structural course beneath a top course. Larger top size, fewer fines, workable on soft wet ground.

Drain Rock, also called 7/8 clean, is washed with no fines and keeps its voids. Use it for footing drains and infiltration trenches.

Delivery to Rock Island and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. Rock Island sits in Douglas County, and we also deliver to East Wenatchee, Bridgeport, Waterville, Mansfield and Orondo.

Deciding between tons and yards is the first step. Each product page has a calculator to help you size the load before you order.

A dump truck tips your material in one pile on site. Have the drop spot clear and reachable, and the rest is straightforward.

Questions

What should I have ready when the truck arrives?

Have the drop area clear of vehicles, equipment and overhead lines. The truck needs room to reach the spot and tip the load in one pile, so keep the approach open and free of soft ground.

If a fence or gate is in the way, open it ahead of time. Once the pile is down, you move it from there.

What is the best base under pavers in Rock Island?

Paver work here usually takes two courses. Put 1 1/4 minus down first as the structural layer, because it carries load and stays workable on soft ground.

Bed the pavers on crusher dust, which compacts tight rather than draining. Where a washed stone is wanted instead, 3/8 clean works in the joint.
