Crushed Stone, Sand and Gravel in Mabton, WA

Order gravel and aggregate delivery in Mabton, WA by the ton or the yard online. Washington Rock Supply delivers bulk material across Yakima County, and 5/8 minus is the surfacing course most drives and pads here start from.

The ground is dry loess over basalt, so a load that packs hard beats one that soaks up water.

Materials for Mabton Projects

Start with the base course. 5/8 minus, also called crushed surfacing top course or CSTC, is crushed rock with the fines left in.

The fines let it pack hard and shed water instead of soaking it up, which is what you want on a driveway, a parking pad, or a shed slab.

Under that goes 1 1/4 Minus, the crushed surfacing base course, or CSBC. Its larger top size and fewer fines carry load and stay workable on soft, wet ground.

Place it below a 5/8 minus top course on a drive, a parking area, or a slab.

For long rural drives and equipment parking, Driveway Gravel is sold as a blend alongside the graded surfacing courses. Pair it with 5/8 Minus where you want a tight, water-shedding surface.

Washed stone handles water. Drain Rock, also called 7/8 clean, has no fines, so it keeps its voids in a footing drain or infiltration trench.

3/4" Crushed Stone is the washed counterpart for trench backfill, pipe surround and under-slab drainage, and it drains instead of compacting.

Sand and soil finish the job. Washed Sand goes into concrete mixes, paver setting beds and pipe bedding.

Top Soil handles lawn repair and new turf. Shredded Mulch, sold locally as beauty bark, covers planting beds and tree rings.

Ground and Conditions in Mabton

Across the Columbia Basin, Yakima Valley and the channeled scablands, the story is scarcity and then too much at once. Parts of this region take only seven to nine inches of rain a year, so the ground sits dry and loose.

When a thunderstorm or a rapid thaw lands, the silt sheds water rather than absorbing it.

That shapes what you put down. Windblown loess over basalt gives a fine, dry surface that moves with wind and cuts into rills under short, violent runoff.

Where flood gravel sits at the surface, water disappears straight down instead.

Base and driveway surfacing is the answer on both counts. A minus product with the fines left in compacts into a hard, water-shedding surface on dry silt.

Where water needs to leave, a washed stone such as drain rock keeps open voids in the trench or bed.

Timing matters. Eastern Washington's wet weather season for erosion control runs October 1 through June 30.

Once snow falls or the ground freezes, placing and compacting base material stops being practical, and eastern winters freeze hard.

Delivery to Mabton and the Surrounding Area

Order online and choose your quantity by the ton or the yard. Each product page has a calculator, and you pick a delivery date at checkout.

A dump truck then tips the load in one pile at your site.

Have the drop spot clear and reachable before the truck arrives. Bulk loads go where the truck can back in and tip, so keep gates open, overhead lines in mind, and loose items out of the way.

The driver tips the pile and leaves it there.
