Order Gravel, Stone and Soil in Bow, WA

Washington Rock Supply handles gravel and aggregate delivery in Bow, WA, and the ground here shapes what you order. Across the Puget Sound lowland the soil is glacial, with a dense till cap sitting over sand and clay.

That till holds winter rain near the surface instead of letting it drain. A pad or drive built on it needs the right sub-base first.

5/8 minus, the crushed surfacing top course, is where most surfaces finish.

Delivery to Bow and the Surrounding Area

You order online and pick your quantity by the ton or by the yard. Each product page has a calculator, so you can size a load before you check out.

Choose a delivery date at checkout and a dump truck tips the material on site in one pile.

Bow sits in Skagit County, and delivery reaches the surrounding towns, including Mount Vernon, Anacortes, Sedro-Woolley, Burlington and La Conner. Give the truck room to reach the drop point and the load lands where you want it.

Materials for Bow Projects

This is fill and sub-base country. Plenty of lots around Bow need grade raised before anything else happens, whether that is a shop slab, a parking pad or a building pad for a new structure.

Fill dirt, which local yards also call common borrow, raises grade and backfills over-excavations.

Once the grade is where it needs to be, the structural course goes down. 1 1/4 minus, the crushed surfacing base course or CSBC, carries load and stays workable on soft wet ground.

It sits below a 5/8 minus top course on a drive or parking area.

For a patio or paver walkway, the setting bed matters as much as the base. Stone Screenings, sold as crusher dust or 3/8 minus, compacts rather than drains, which is what a bedding layer needs.

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

Where water has to move instead of being held, the clean products do the work. Drain Rock, also called 7/8 clean, is washed with no fines, so it keeps its voids in a footing drain or French drain.

Below a slab, 3/4" Crushed Stone drains instead of compacting.

Ground and Conditions in Bow

The ground across the Puget Sound lowland is glacial, laid down by the Vashon ice sheet. A dense till cap sits on top, its lower part hard enough that crews call it hardpan.

Below that is advance outwash sand, and under it the silt and clay of the Lawton beds.

That layering is the reason water behaves the way it does here. Rain soaks the loose upper soil, reaches the dense till and stops.

The water table sits close to the surface all winter rather than draining away, which is perched water.

An under-built base on till shows it in February. A drive that was firm in August ruts once saturation softens it, so the sub-base has to take the water sideways to daylight.

That is the job footing drains and washed drain rock do on this ground.

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 and paver work is scheduled for the dry months.

Winter work needs the grade kept covered. Winters here are mild and wet, and the ground seldom freezes deep, so it is saturation rather than frost that softens a base.

Questions About Ordering in Bow

What is the best base under pavers in Bow?

A compacted minus product, not a clean one. 1 1/4 minus gives you the structural course, then 5/8 minus or crusher dust beds the pavers.

The fines are left in these materials so they pack hard. On till, add a drainage layer so perched winter water has somewhere to go.
