Order Gravel, Stone and Soil in Omak, WA

Washington Rock Supply handles gravel and aggregate delivery in Omak, WA, by the ton or by the yard. Size the load with the calculator on each product page, pick a delivery date at checkout, and a dump truck tips it on your site.

Start with 5/8 minus, the crushed surfacing top course this market calls CSTC. It is the Washington default surfacing layer for drives, pads and shop slabs, because the fines stay in and it packs hard.

On the glaciated ground around here, that matters.

Delivery to Omak and the Surrounding Area

You order online and choose a quantity by the ton or by the yard. The calculator on each product page helps you size the load before you commit, and delivery is scheduled when you check out.

A dump truck tips the material in one pile at your site. Plan where that pile should sit before the truck arrives, since the load is dropped and left where it lands.

Omak sits in Okanogan County, and delivery covers the surrounding area, including Okanogan, Brewster, Oroville, Twisp and Coulee Dam. If your job is out on a rural approach or a building pad in the valley, order the same way.

Materials for Omak Projects

Fill and sub-base carry most of the load here, because so much work in this corner starts by raising grade or building up a pad. Get the fill right first, then cap it with a surfacing course that will hold.

Driveways and parking pads

Use Fill Dirt to raise low spots and backfill over-excavations before any granular course goes down.

Under that, place 1 1/4 Minus, the crushed surfacing base course, or CSBC. It has a larger top size and fewer fines than 5/8 minus, so it carries load and stays workable on soft ground.

Cap the drive with 5/8 Minus or a Driveway Gravel blend for a long rural approach.

Patios, pavers and slabs

Bed pavers on Stone Screenings, also sold as crusher dust or 3/8 minus. It is a minus product, so it compacts rather than drains, and it makes a firm setting bed.

Fill paver joints with 3/8" Crushed Stone, a washed stone with no fines. Lock the pavers to a compacted base below, never to the joint stone.

Drains and wet ground

Footing drains, French drains and infiltration trenches take Drain Rock, also called 7/8 clean. It is washed, so it keeps its voids in ground that holds water.

For trench backfill, pipe surround and under-slab drainage, use 3/4" Crushed Stone, the washed counterpart to a minus product.

Ground and Conditions in Omak

This is glaciated mountain country, and the ground shows it. Thin stony soil sits over granite, gneiss and metamorphic rock on the ridges, while till, outwash gravel and lake silt fill the valleys.

That split decides how a base performs. Gravel valley floors drain quickly.

Till and lake silt do not, and water that reaches them sits there instead of leaving.

Most of the year's water arrives as snow and leaves over a few weeks in spring. That saturates valley soils while the ground below is still frozen, which softens an under-built base fast.

Okanogan County frost depth is 24 inches, and the county or city building department sets that figure for your job. Long winters and a slow spring breakup mean frost heave and soft spring ground govern any unbound base.

Spring runoff scours ditches, culverts and gravel roads during breakup. Streambank cutting in the valley rivers and bare burned slopes shedding soil and rock follow the region's wildfire seasons.

The working season is short. Base, drive and paver work fits between spring breakup and the autumn freeze, and the window narrows the higher and further north your site sits.

Questions from Omak Buyers

What is the best base under pavers in Omak?

Use 1 1/4 Minus as the structural course, placed below the bedding. It carries load and stays workable on the soft spring ground this valley is known for.

Above it, bed the pavers on Stone Screenings, which packs tight and holds a setting bed. Keep the base granular and well drained, and keep the joint stone clean so it does not trap water under the pavers.
