Bulk Aggregates for Pathways in Winlock, WA

Washington Rock Supply sells gravel and aggregate delivery in Winlock, WA by the ton or the yard, ordered online. Contractors and homeowners both work through the same catalog here, and both tend to start with 5/8 minus because it packs hard and sheds water.

Across the Lower Columbia, Chehalis valley and the Willapa Hills, fine-grained terrace soils hold water rather than shedding it, so the material under a path matters as much as the material on it.

Ground and Conditions in Winlock

In this part of the state, a thin base course shows its weakness fast. Soft ground under a path or drive pumps and ruts, and a fines-bearing top course placed too thin over wet silt breaks up at the edges.

The fix is a free-draining structural course under the surface layer. That is why pads and drives here get a base course first, then a compacting top course over it.

The region's wet season rule also shapes timing. Exposed unworked soil is limited to two days on site, so grading is planned around the rain.

Grading in the river valleys is scheduled around the winter flood season as much as around rainfall. Ground here softens because it is full of water, not because it froze and thawed.

Frost depth figures are set by the county or city building department.

Materials for Winlock Projects

Fines and screenings do the fine work on paths and walkways here. Where a drive needs structure, the same family of materials scales up.

Walkway and path materials

Walkway Gravel, also called 1/4 minus or pathway gravel, is the fine end of the minus range. It packs down tight underfoot, which makes it the practical choice for garden paths and side yards.

Stone Screenings, or crusher dust, run a little finer still. A minus product compacts rather than drains, so it beds pavers and flagstone and fills joints.

Where you want a washed, fines-free stone instead, 3/8" Crushed Stone works in paver joints and small drain runs.

Base and structural materials

5/8 Minus is the Washington default surfacing course, known locally as crushed surfacing top course, or CSTC. The crusher fines are left in, so it compacts and holds where a drive, parking pad or shed slab sits.

1 1/4 Minus, or crushed surfacing base course, CSBC, goes below that top course. The larger top size and fewer fines let it carry load on soft wet ground.

Drainage and finishing materials

Drain Rock, called 7/8 clean locally, is washed with no fines. It keeps its voids in footing drains and French drains where water sits on tight ground.

For edging and beds, Natural Pea Gravel is rounded and washed, so it will not compact. Pair the fines materials with a washed stone wherever water needs to move.
