1/4 Minus, Stone and Soil Delivery in Edmonds, WA

Washington Rock Supply handles gravel and aggregate delivery in Edmonds, WA, and the ground here shapes what you should order. Across the Puget Sound lowland, rain soaks the loose upper soil, hits the dense till below it, and stops.

That perched water sits close to the surface all winter. It is why 5/8 minus, the local crushed surfacing top course, does so much of the work on drives and pads around here.

Materials for Edmonds Projects

Water that cannot drain down has to go sideways, and that is what washed stone is for. Drain rock, also called 7/8 clean, has no fines left in it, so it keeps its voids and gives perched water somewhere to move.

Use it in footing drains, French drains, curtain drains and infiltration trenches. Where a downspout or a drywell needs to pass water quickly, a clean stone does the job that a minus product cannot.

From there, the sizes step down to what each one is good for.

Below the top course, 1 1/4 minus (crushed surfacing base course, or CSBC) is the structural layer. It has a larger top size and fewer fines, so it carries load and stays workable on soft wet ground under a 5/8 minus surface.

On the fine end, crusher dust beds pavers and flagstone, and 1/4 minus packs down tight underfoot for garden paths and side yards.

For planting, Top Soil is screened for lawns and grading out settlement, and Washed Sand suits concrete mixes and paver setting beds.

Delivery to Edmonds and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. Each product page has a calculator if you want to size the load before you commit.

A dump truck then tips the material on site in one pile. The driver tips the load and drives on; nothing is spread or placed for you.

Washington Rock Supply delivers across Snohomish County, including Everett, Marysville, Lynnwood, Lake Stevens and Mukilteo alongside Edmonds.

Ground and Conditions in Edmonds

The wet season runs October through April, and exposed soil has to be stabilized within two days in that window under the state stormwater manual for western Washington. Summer allows seven.

That gap decides a lot of scheduling. Base work, paving and paver setting are best held for the dry months, and winter work means keeping the grade covered.

The ground itself is glacial, laid down by the Vashon ice sheet. A dense till cap sits over advance outwash sand, with silt and clay below that, and the lower till is hard enough that crews call it hardpan.

Winter rain perches where the outwash sand meets the clay, and that is what puts coastal bluffs on the landslide maps and undercuts cut slopes and fill on a smaller scale.

Frost is not the problem here. Mild, wet winters mean it is saturation that softens a base, so a drive that was firm in August can rut by February.

What gravel is best for a driveway in Edmonds?
