Bulk Aggregates for Pathways in Greenacres, WA

Order gravel and aggregate delivery in Greenacres, WA online by the ton or by the yard. Washington Rock Supply delivers bulk material across Spokane County, and 5/8 minus is the surfacing course most local work starts from.

The valley ground here is Ice Age flood gravel: cobbles, gravel and sand dumped by the Missoula floods, with a thin loess cap on the ground south and west of the city.

Ground and Conditions in Greenacres

Start with what a thin base does on this ground. The valley gravel is open enough that water moves through it fast, so a path or drive built on too little rock settles and ruts at the first spring thaw.

Compacted fill and shallow basalt shelves are where the wet spots show up. Water sits on those instead of dropping away, and the surface above them moves.

Across the Spokane and the Selkirk foothills, the ground freezes to depth in winter and thaws hard in spring. Repeated freeze-thaw works on any unbound surface, so the granular course has to be thick enough to hold its shape.

Spokane sets its footing depth well below the western Washington figure for that reason, with a frost depth of 24 inches in the Spokane Municipal Code design criteria. That is a footing depth set by the building official, not a target for a gravel base.

Timing matters too. Eastern Washington's wet weather season for erosion control runs October 1 through June 30, and runoff cutting the loess on the hills south of the city carries sediment into the aquifer's recharge ground when a site is left open.

Materials for Greenacres Projects

Fines and screenings do the work on paths and walkways here. A minus product keeps its crusher fines, so it compacts underfoot instead of staying loose.

Walkway Gravel, sold as 1/4 minus or quarter minus, is the fine end of that range. Use it for garden paths, side yards and firm walking surfaces that need to pack down tight.

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 a path that has to shed water instead, 3/8" Crushed Stone is washed and fines-free. It suits paver joints, permeable paver setting beds and small drain runs.

Where a path meets a drive or a parking pad, build up with 5/8 Minus. Locally that is 5/8 minus, or crushed surfacing top course (CSTC): crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

Under that, 1 1/4 Minus is the structural course, also called crushed surfacing base course (CSBC). Larger top size and fewer fines let it carry load and stay workable on soft, wet ground.

For drainage beside a path or under a downspout, Drain Rock, or 7/8 clean, is washed with no fines, so it keeps its voids where water perches.
