Bulk Aggregates for Patios in Chelan, WA

Washington Rock Supply handles gravel and aggregate delivery in Chelan, WA for two kinds of buyers: contractors setting paver patios and flatwork, and homeowners rebuilding a walk or a parking pad. Both need the same thing, a base that stays put.

In Chelan County that starts with 5/8 minus, the crushed rock Washington crews call crushed surfacing top course.

The valley floors here carry glacial and river gravel, while the slopes above town are thin, stony ground over volcanic and granitic rock. That mix decides how a patio base behaves once snowmelt starts moving.

Ground and Conditions in Chelan

A thin base shows its failure at the edges first. The pavers rock, joints open, and the surface dishes where water has been sitting under it.

Chelan sits in the Cascade Range and the east-slope valleys, where the ground water story splits in two. The west slope sheds heavy annual rain off steep ground, and the east-slope valleys are dry and get their trouble all at once.

What arrives here is snowmelt and cloudburst runoff landing on ground with little cover. On a patio that means a base that holds its shape when it is wet, not one that pumps and shifts.

Frost heave is a genuine east-slope issue, where cold clear nights follow sunny days. Frost depth is set by the local building department, so confirm the number that applies to your project rather than assuming a lowland figure.

Steep-slope runoff scours road shoulders, ditches and culvert outfalls, and bare burned ground keeps shedding sediment for years after a fire. Work in the mountain valleys runs roughly late spring to early autumn, later at elevation.

Materials for Chelan Projects

Bedding and base material is what makes a patio last, so it is worth getting the layers right before anything else arrives on site.

5/8 Minus

This is the Washington default surfacing course, sold locally as crushed surfacing top course or CSTC. It is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

Use it for driveway topping, parking pads, shed and shop slabs, and the compacted layer under a patio.

Order 5/8 Minus when you want a surface that tightens up underfoot and stays put.

1 1/4 Minus

For the structural course under a patio, drive or slab, 1 1/4 Minus is the base course. Its larger top size and fewer fines carry load and stay workable on soft, wet ground.

It goes below a 5/8 minus top course.

Crusher Dust

Stone Screenings, called crusher dust or 3/8 minus here, is your setting bed. It is a minus product, so it compacts rather than drains, which is exactly what you want under pavers and flagstone.

It also fills joints.

3/8" Crushed Stone

Where a washed, fines-free stone is wanted instead of a minus, 3/8" Crushed Stone does the job. It suits paver joints, permeable paver setting beds and small drain runs.

Drain Rock

Drain Rock, also sold as 7/8 clean or washed rock, keeps its voids because the fines are washed out. That matters where a perched water table sits on till.

Use it for footing drains, French drains and infiltration trenches.

Delivery to Chelan and the Surrounding Area

Order online, and choose your quantity by the ton or by the yard. If you are not sure which figure you need, each product page has a calculator that helps you size the load before checkout.

You pick a delivery date at checkout and a dump truck tips the load on site as one pile. Washington Rock Supply serves Chelan and the rest of Chelan County, including Wenatchee, Cashmere, Leavenworth, Manson and Entiat.

Getting the quantity close matters more than anything on a bulk order, because a patio base is measured in volume and delivered by weight. Have your area and intended depth ready before you order, and let the calculator handle the rest.
