Order Gravel, Stone and Soil in Anacortes, WA

Washington Rock Supply handles gravel and aggregate delivery in Anacortes, WA, and the ground here shapes what you order. Across the Puget Sound lowland, a dense till cap sits under the upper soil, and its lower part is hard enough that crews call it hardpan.

Water perches on that layer instead of draining away.

5/8 minus is the Washington default surfacing course, crushed rock with the fines left in so it packs hard and sheds water instead of soaking it up. On ground like this, the base under it does as much work as the surface.

Delivery to Anacortes 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 tips your material on site in one pile. That is the whole of it, so plan where you want the pile to sit before the truck arrives.

Anacortes sits in Skagit County, and delivery covers the city and the surrounding area. We also deliver to Mount Vernon, Sedro-Woolley, Burlington, La Conner and Concrete.

Materials for Anacortes Projects

Fill and sub-base do the heavy lifting on a lot that needs raising. If your building pad or drive sits low, or an over-excavation has to go back in, the granular courses below the surface are what make the finished grade hold.

Start with Fill Dirt to raise grade and build up low spots before a granular course goes down.

Above that, 1 1/4 Minus is the structural course under a drive, parking area or slab. It is also called crushed surfacing base course, or CSBC.

Larger top size and fewer fines than 5/8 minus, so it carries load and stays workable on soft wet ground.

Then 5/8 Minus goes on top as the surfacing course, also called crushed surfacing top course or CSTC. For a long rural drive, farm approach or equipment parking, Driveway Gravel is sold as a driveway blend alongside the graded surfacing courses.

Drainage is the other half of the job. Drain Rock, also called 7/8 clean, is washed with no fines, so it keeps its voids in a footing drain or infiltration trench.

For a patio, Stone Screenings bed pavers and flagstone, and Walkway Gravel packs down tight underfoot on garden paths and side yards.

Ground and Conditions in Anacortes

The ground across the Puget Sound lowland is glacial, laid down by the Vashon ice sheet. A dense till cap sits over advance outwash sand, and below that are the silt and clay of the Lawton beds.

The lower till is hard enough that crews call it hardpan.

That layering drives the drainage problem. Rain soaks the loose upper soil, reaches the dense till and stops, so the water table sits close to the surface all winter instead of draining away.

Anything built on till needs the water taken sideways to daylight.

That is why footing drains and washed drain rock do so much of the work here. A base that was firm in August can rut in February, because it is saturation rather than frost that softens it.

The wet season runs October through April. Under the state stormwater manual for western Washington, exposed soil must be stabilized within two days in that window against seven days in summer.

Base, paving and paver work is scheduled for the dry months, and winter work needs the grade kept covered.

Questions About Ordering in Anacortes

What is the best base under pavers in Anacortes?

On till ground, start with 1 1/4 Minus as the structural course, since it carries load and stays workable when the ground is soft and wet. Bed the pavers themselves in Stone Screenings, also called crusher dust, which compacts rather than drains.

Where you want a washed, fines-free layer instead, 3/8 clean works for joints and small drain runs.

Do you supply contractors working in Anacortes?

Yes. Contractors order the same way as anyone else: online, by the ton or by the yard, with a delivery date chosen at checkout.

Fill Dirt, 1 1/4 Minus and 5/8 Minus cover grade raising and base work, and Drain Rock covers the footing and trench drainage that till ground calls for.
