Buy Fill Dirt in Colfax, WA

Washington Rock Supply brings gravel and aggregate delivery in Colfax, WA, with 5/8 minus as the local default for drives, pads and shop slabs. The ground here is deep Palouse loess, fine windblown silt that works easily and moves easily too.

That shapes what you order before you ever set a grade.

You pick the material, order online by the ton or yard, and a dump truck tips it on your site.

Materials for Colfax Projects

Grading and bed prep start long before anything hard goes down. Fill dirt raises grade, backfills over-excavations and builds up low spots so a granular course has something level to sit on.

Order Fill Dirt when the site needs shaping first.

Once grade is set, topsoil and garden soil finish the job. Screened topsoil goes down for lawn repair, new turf and grading out settlement.

A garden blend of screened soil and compost is the better choice for raised beds, vegetable gardens and new planting beds. Both are listed here as Top Soil and Garden Soil.

Around those beds, beauty bark is the local name for landscape bark, and it covers planting beds, tree rings and slopes as Shredded Mulch.

Base, Washed Stone and Sand

For the structural work under a drive, parking area or slab, 1 1/4 minus is the base course, sold in Washington as CSBC. It carries load and stays workable on soft wet ground.

The 5/8 minus top course, or CSTC, is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up. Order 1 1/4 Minus under 5/8 Minus.

Where water has to move instead of being held, you want a washed stone with the fines taken out. Drain rock, also called 7/8 clean, keeps its voids in footing drains, French drains and infiltration trenches.

Crusher dust, or 3/8 minus, does the opposite job: it compacts into paver and flagstone bedding and joint filling. Both are listed as Drain Rock and Stone Screenings.

Sand rounds out an order. Washed sand goes into concrete mixes, paver setting beds and pipe bedding, and it is washed so silt does not sit in the mix through the wet season.

Mason sand is the finer grade for mortar, stucco and joint sweeping. See Washed Sand and Mason Sand.

Ground and Conditions in Colfax

The problem across the Palouse is water that cannot get in. When the top inch of loess thaws over ground still frozen below, rain and snowmelt run across the surface instead of soaking down.

Every slope turns into a drainage path, and anything built on one needs its runoff routed before it starts cutting.

Loess is also easy to move once it is wet and bare. Sheet and rill erosion on long cultivated slopes is driven by rain falling on frozen ground, which is why the thaw is the risk period here rather than high summer.

Wet weather in eastern Washington runs October 1 through June 30, so the working season is long and dry through summer and closes when the ground freezes.

Practically, that means two things. Plan granular work for the dry stretch, and put a washed layer where water collects so it drains instead of sitting under a compacted minus.

On wet ground, 1 1/4 minus carries load better than a fine top course alone.

Each product page has a calculator you can use to help size the load before you check out.

What stone should I use for drainage in Colfax?

Use a washed, fines-free stone so it keeps its voids. Drain rock, also called 7/8 clean, suits footing drains, French drains and infiltration trenches.

Where you need a smaller washed stone, 3/4 clean works for trench backfill and pipe surround. Both drain rather than compact, which matters on loess that sheds water across the surface.
