Gravel and Aggregate Delivery in Vancouver, WA

If you are planning a driveway, a parking pad or a drainage run, Washington Rock Supply handles gravel and aggregate delivery in Vancouver, WA. Most of it starts with 5/8 minus, the crushed surfacing top course that packs hard and sheds water.

Ground here is river terrace silt and gravel, so a free-draining course under a pad matters more than depth alone. Order online and a dump truck tips the load on site.

Materials for Vancouver Projects

Base and driveway surfacing is the core of what a Vancouver drive needs. The two minus products below are the structural pair: a larger base course under a finer top course.

1 1/4 minus, also called crushed surfacing base course or CSBC, is the structural course under a drive, parking area or slab. Its larger top size and fewer fines let it carry load and stay workable on soft wet ground.

5/8 minus, also called crushed surfacing top course or CSTC, is the Washington default surfacing course. The crusher fines stay in the mix, so it compacts into a hard surface instead of soaking up water.

For a long rural approach or equipment parking, Driveway Gravel is sold as a driveway blend alongside the graded surfacing courses. It gives you a single material for the full drive.

Where water needs to move rather than sit, Drain Rock (7/8 clean) is washed with no fines, so it keeps its voids. It suits footing drains, French drains and infiltration trenches.

For setting beds, Stone Screenings (crusher dust) compacts under pavers and flagstone. Walkway Gravel (1/4 minus) packs tight underfoot on garden paths and side yards.

Ground and Conditions in Vancouver

Across the Lower Columbia, Chehalis valley and the Willapa Hills, the ground is river terrace silt and gravel, weathered marine sandstone in the hills, and volcanic ash on ground draining Mount St. Helens.

Fine-grained terrace soils hold water rather than shedding it.

Valley flooding and slow-draining silt drive the drainage question. Winter storms back water up in the valleys, and pads and drives need a free-draining course under them so they are not sitting in it.

Erosion follows the same pattern. Shallow slides in weathered hill soils after long rain, riverbank scour, and sediment washing off cleared ground all point to keeping water moving instead of ponding it.

The wet season runs October to April, with two days the limit on exposed unworked soil. Grading is planned around the winter flood season as much as around the rain.

Winters here are mild and wet with only shallow frost. Ground that softens here softens because it is full of water, not because it froze and thawed.
