Bulk Aggregates for Pathways in Carnation, WA

Washington Rock Supply brings gravel and aggregate delivery in Carnation, WA to driveways, paths, drainage trenches and garden beds. If you are building a walking surface, start with 5/8 minus.

It is crushed rock with the fines left in, so it packs hard and sheds water rather than soaking it up.

Carnation sits in King County on ground that holds winter rain near the surface. That shapes both what you order and when you order it.

Ground and Conditions in Carnation

Across the Puget Sound lowland, the ground is glacial: a dense till cap over sand, with silt and clay below. The lower part of that till is hard enough that crews call it hardpan.

Rain soaks the loose upper soil, hits the dense till and stops. Perched water sits close to the surface all winter instead of draining away, and it is what undercuts cut slopes and fill.

A path or pad on that ground fails at the edges first. The surface stays firm while the shoulder softens and pushes out, and the surface starts to break up from the sides in.

The fix is to take water sideways to daylight rather than letting it sit. A washed layer under a compacted surface does that work, and it is the reason drain rock and washed stone matter as much as the surface course here.

The wet season runs October through April. Exposed soil has to be stabilized within two days in that window, against seven days in summer, so path and paver work is usually scheduled for the dry months.

Materials for Carnation Projects

Fines and screenings carry walking surfaces in this area. The fine end of the minus range packs down tight underfoot, which is what a garden path or side yard needs.

Walkway Gravel, also called 1/4 minus or quarter minus, is the standard choice for garden paths and firm walking surfaces. It knits together under foot traffic instead of staying loose and shifting.

Stone Screenings, or crusher dust, is a minus product used for paver and flagstone bedding, joint filling and setting beds. Because it compacts rather than drains, keep it where you want a surface to lock up.

For a path that has to stay open to water, use a washed stone instead. 3/8" Crushed Stone, called 3/8 clean locally, has no fines left in it, so it drains where a minus product would seal.

Under a drive or parking pad, the structural course is 1 1/4 Minus, known locally as 1 1/4 minus or CSBC. It goes below a 5/8 minus top course and carries load on soft wet ground.

Where water has to move, Drain Rock (7/8 clean) keeps its voids under a perched water table. Natural Pea Gravel suits play areas, dog runs and planting beds, and it will not compact, so edge it where it can wander.

For planting beds and tree rings, Shredded Mulch is sold here under its Washington trade name, beauty bark.
