Fill and Base Material Delivered in Cashmere, WA

Looking for gravel and aggregate delivery in Cashmere, WA, for a pad that has to come up to grade? Washington Rock Supply delivers bulk material to sites across the city and Chelan County.

The place to start is 5/8 minus, the crushed rock this market also calls crushed surfacing top course.

It is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up. That makes it a surfacing course for drives, parking pads and shop slabs.

Delivery to Cashmere and the Surrounding Area

You order online, pick a quantity by the ton or by the yard, and choose a delivery date at checkout. Each product page has a calculator if you want to size the load before you commit.

A dump truck tips the load in one pile on your site. That is the whole of it, so plan where you want the pile to land before the truck arrives.

Washington Rock Supply delivers across Cashmere and to the rest of Chelan County, including Wenatchee, Chelan, Leavenworth, Manson and Entiat.

Materials for Cashmere Projects

Raising grade and building pads is the work here, and it takes two courses: a structural fill or base underneath, then a surfacing course on top. The material you choose depends on what the pad has to carry.

Sub-base and fill

1 1/4 Minus, also called crushed surfacing base course or CSBC, is the structural course under a drive, parking area or slab. It has a larger top size and fewer fines than 5/8 minus, so it carries load and stays workable on soft wet ground.

Fill Dirt, or common borrow, raises grade and backfills over-excavations before a granular course goes down. It is not the same as gravel borrow, which is the granular structural fill.

5/8 Minus goes on top as the surfacing course. It packs hard under tires and sheds meltwater instead of holding it.

Drainage and bedding

Drain Rock, also called 7/8 clean or washed rock, is washed with no fines, so it keeps its voids. Use it for footing drains, French drains and infiltration trenches.

Stone Screenings, or crusher dust, is a minus product that compacts rather than drains. It beds pavers and flagstone and fills joints.

Walkway Gravel, or 1/4 minus, is the fine end of the minus range. It packs down tight underfoot for garden paths and side yards.

Ground and Conditions in Cashmere

Across the Cascade Range and the east-slope valleys, the ground is thin and stony over volcanic and granitic rock on the slopes. Valley floors carry glacial and river gravel.

Neither one is a uniform base.

The east-slope valleys are dry, some under 10 inches a year, and the trouble is snowmelt and cloudburst runoff arriving all at once on ground with little cover. Water that reaches an under-built base has nowhere to go.

That is why a pad gets a fill or base course sized for the load, then a surfacing course that sheds. Frost heave is a real east-slope problem, and published Washington frost depths run from 12 inches on the west side to 24 inches at Spokane and in Okanogan County.

Confirm the local number with the building department.

The working window in the mountain valleys runs roughly late spring to early autumn, later at elevation. Snow closes the high ground, so grade work is easier to schedule inside that window.
