Order Gravel, Stone and Soil in Mount Vernon, WA

Washington Rock Supply handles gravel and aggregate delivery in Mount Vernon, WA. Start with the calculator on any product page to size your load, then order by the ton or the yard.

For most drives and pads around here, that load is 5/8 minus, the crushed surfacing top course with the fines left in. It packs hard and sheds water instead of soaking it up.

Delivery to Mount Vernon and the Surrounding Area

You order online, pick a quantity by the ton or by the yard, and choose a delivery date at checkout. A dump truck then tips the load on your site in one pile.

Mount Vernon sits in Skagit County, and delivery covers the city and the surrounding area. That includes Anacortes, Sedro-Woolley, Burlington, La Conner and Concrete.

Have the drop spot clear before the truck arrives. The driver tips the pile and pulls out, so the spot needs room for a truck to reach it and turn around.

Materials for Mount Vernon Projects

A lot of the work here starts with grade. Building pads, shop slabs and low driveways all need material under them before anything else goes down, and that is where fill dirt and a structural base course come in.

Fill Dirt raises grade, backfills over-excavations and builds up low spots before a granular course goes down.

Above the fill, 1 1/4 Minus is the structural course. It is also called crushed surfacing base course, or CSBC, and it carries load on soft wet ground better than a finer material.

Then 5/8 Minus goes on top as the surfacing course for a driveway, parking pad or shed slab. It is the Washington default, and the fines are what let it pack hard.

For a patio, the order changes. Stone Screenings, also called crusher dust or 3/8 minus, is a compacting material for paver and flagstone bedding and joint filling.

Walkway Gravel, or 1/4 minus, packs down tight underfoot on garden paths and side yards.

For a drain, you want washed stone instead of a minus. Drain Rock, or 7/8 clean, keeps its voids in footing drains, French drains and infiltration trenches.

3/4" Crushed Stone is the washed counterpart for trench backfill and pipe surround.

Ground and Conditions in Mount Vernon

Across the Puget Sound lowland, the ground is glacial. A dense till cap sits over advance outwash sand, with silt and clay below that.

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

That till is what causes the trouble. Rain soaks the loose upper soil, reaches the dense layer and stops, so perched water sits close to the surface all winter instead of draining away.

An under-built base on ground like that softens from saturation, not from frost. Mild wet winters mean the ground seldom freezes deep, so a drive that was firm in August can rut in February.

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 on this side of the state.

Timing matters too. The wet season runs October through April, and exposed soil must be stabilized within two days in that window against seven days in summer.

Base, paving and paver work fits the dry months.

What is the best base under pavers in Mount Vernon?

Use a compacting material, not a draining one. Crusher dust, sold here as Stone Screenings or 3/8 minus, is the fine end of the minus range and compacts rather than drains, which is what a setting bed needs.

Below it, 1 1/4 Minus carries the load. For permeable pavers, the washed sizes are the ones with the fines taken out.

Do you supply contractors working in Mount Vernon?

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

The truck tips the load on site in one pile. Quantities are ordered by the ton or by the yard, and each product page has a calculator to size the load.
