3/8 Clean for Patios in Ellensburg, WA

Order gravel and aggregate delivery in Ellensburg, WA by the ton or the yard. Washington Rock Supply drops bulk material at your site, from 5/8 minus to bedding sand.

Start with 5/8 minus if you are building a drive, a parking pad or a shop slab. It packs hard and sheds water instead of soaking it up.

Then pick the layer that sits under your pavers or flatwork.

Ground and Conditions in Ellensburg

Bedding is where a thin base shows itself. A paver laid on crusher dust over soft ground moves at the joint, then the whole field follows.

Across the Cascade Range and the east-slope valleys, the ground under a valley floor is glacial and river gravel, and slopes carry thin stony soil over rock. On this side of the state the trouble is snowmelt and cloudburst runoff arriving at once on dry ground with little cover.

That runoff is what scours shoulders, ditches and culvert outfalls. Water moving under a patio edge takes the fines with it and leaves a void.

The working window on the high ground runs roughly from late spring to early autumn, later at elevation. October 1 through June 30 is treated as the wet weather season for erosion control on the east side.

Winters here are real, and cold clear nights after sunny days drive a genuine freeze-thaw cycle. Frost heave in a gravel drive is an east-slope problem in a way it is not down in the Puget lowland.

Frost depth is set by the local building department. Published Washington figures run from 12 inches on the west side to 24 inches at Spokane and in Okanogan County, so confirm the number that applies to your permit.

Materials for Ellensburg Projects

Bedding decides how a patio or walkway ages. Get the layer under the pavers right and the surface stays flat through a Kittitas County winter.

5/8 Minus

The Washington default surfacing course. Crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

Use it for driveways, parking pads and shed or shop slabs. Locally it also goes by crushed surfacing top course, or CSTC.

5/8 Minus

Crusher Dust for Setting Beds

Crusher dust, also called 3/8 minus or screenings, is the fine end of the minus range. It compacts rather than drains, which is what you want under a setting bed.

Use it for paver and flagstone bedding, joint filling and setting beds.

Stone Screenings

3/8 Clean for Joints and Permeable Beds

Washed, with the fines taken out, so it drains instead of compacting. Use 3/8 clean for paver joints, permeable paver setting beds and small drain runs.

3/8" Crushed Stone

1 1/4 Minus for the Base Course

The structural course under a drive, parking area or slab, placed below a 5/8 minus top course. Larger top size and fewer fines, so it carries load and stays workable on soft wet ground.

Also called crushed surfacing base course, or CSBC.

1 1/4 Minus

Washed Sand and Drain Rock

Washed sand goes into concrete mixes and paver setting beds. Drain rock, also called 7/8 clean, keeps its voids in footing drains and French drains.

Washed Sand and Drain Rock both work where water has to move.
