Bulk Aggregates for Pathways in Pacific, WA

Washington Rock Supply brings gravel and aggregate delivery in Pacific, WA, and the material names you see here are the ones local yards use. That starts with 5/8 minus, the crushed surfacing top course this market calls CSTC.

It is crushed rock with the fines left in, so it packs down hard.

Pacific sits in King County on the Puget Sound lowland, where a dense till cap sits under most of the ground. Rain that soaks the loose upper soil stops at that layer and stays put all winter.

Ground and Conditions in Pacific

When a path or a drive fails in this area, the surface is rarely the problem. A thin base over the dense till lets the water sit, and the surface rock starts to move and rut underfoot.

A base that was firm in August can soften by February. That is saturation doing the work, not frost.

The fix is a structural course with enough coarse rock to carry load, placed under the top course. Across the Puget Sound lowland the standard pairing is 1 1/4 minus below and 5/8 minus above.

The 1 1/4 minus is the crushed surfacing base course, or CSBC, with a larger top size and fewer fines than the top course.

Paths built over wet ground need the water taken sideways. Drain Rock, sold locally as 7/8 clean, is washed with no fines, so it holds open voids instead of filling in.

The wet season here runs October through April. Exposed soil has to be stabilized within two days in that window, against seven days in summer.

Base, paving and paver work fits best into the dry months.

Materials for Pacific Projects

Fines and screenings do the detail work on paths and walkways around Pacific, and they are the materials to get right first. The fine end of the minus range packs tight underfoot, which is what a walking surface needs.

Walkway Gravel, known here as 1/4 minus or quarter minus, is the standard for garden paths, side yards and any surface that has to stay firm. It compacts rather than drains, so it belongs above a base that already handles the water.

Stone Screenings, or crusher dust, is the same fine range put to a different job. Use it as bedding under pavers and flagstone and for filling the joints between them.

A minus product compacts, which is exactly what a setting bed should do.

Where you want a path that drains, switch to a washed stone. 3/8" Crushed Stone, called 3/8 clean locally, has the fines washed out, so it stays open.

It suits permeable paver joints, permeable setting beds and small drain runs.

For the structural work under a drive, a parking pad or a shed slab, 1 1/4 Minus carries the load. The larger top size and lower fines content keep it workable on soft, wet ground.

Rounded stone stays separate from the crushed products. Natural Pea Gravel is washed and rounded, so it will not compact, and it suits play areas, dog runs and planting beds.

It should be edged where it can wander.

Delivery to Pacific and the Surrounding Area

You order online and choose a quantity by the ton or by the yard. Each product page has a calculator to help you size the load before you check out.

Pick a delivery date at checkout and a dump truck tips the material on your site.

The truck tips the load in one pile, so it helps to know where that pile should land before the truck arrives. Bulk delivery reaches Pacific and the rest of King County, including Seattle, Bellevue, Kent, Renton and Federal Way.

Material arrives as loose bulk, so have the drop area clear of vehicles, equipment and anything you do not want buried. If the ground is soft from winter rain, the truck needs a firm approach it can reach without sinking.
