3/8 Clean for Pathways in Sultan, WA

Washington Rock Supply brings gravel and aggregate delivery in Sultan, WA to driveways, pathways, drainage runs and garden beds. 5/8 minus is the local base course, and the fines left in it are what make it pack hard.

Across the Puget Sound lowland, rain stops when it hits dense glacial till. Water then sits close to the surface all winter, so what you put down has to shed it.

Ground and Conditions in Sultan

That shallow perched water is the reason a thin base fails here. The rock looks fine in August, then ruts and pumps in February when the ground underneath stays saturated.

The fix is a base that keeps its structure while wet, not more rock piled on a soft grade. A minus product with the fines left in compacts into a surface that sheds water instead of soaking it up.

On ground that stays wet, a washed stone under the compacted course carries water sideways to daylight. Drain rock holds its voids where a perched water table sits on till, which is the job a fines-bearing rock cannot do.

Timing matters too. The wet season runs October through April, and exposed soil on western Washington sites has to be stabilized within two days in that window.

Winter orders are best kept covered until they go down.

The ground seldom freezes deep in this region, so saturation softens a base rather than frost. Frost depth is set by the local building official, and 18 inches is published in King County for footing work.

Materials for Sultan Projects

Paths and walkways are where the fine end of the minus range does its best work. 1/4 minus, sold locally as pathway gravel or walkway gravel, packs down tight underfoot and holds a firm walking surface on a garden path or side yard.

For paver and flagstone bedding, crusher dust (also called 3/8 minus or screenings) is the setting bed material. It is a minus product, so it compacts under the stone rather than draining away beneath it.

Where a washed, fines-free stone is wanted instead, 3/8 clean fills paver joints and small drain runs. Keep the two apart: minus compacts, clean drains.

5/8 minus stays the default surfacing course for driveways, parking pads and shed slabs.

• Stone Screenings for paver and flagstone bedding

Below a 5/8 minus top course, 1 1/4 minus carries the load on soft ground. Washington yards call it crushed surfacing base course, or CSBC.

Round the planting out with Top Soil for lawn repair and grading out settlement, and Shredded Mulch, listed locally as beauty bark, for beds and tree rings.
