3/8 Clean for Pathways in Kennewick, WA

Washington Rock Supply sells gravel and aggregate delivery in Kennewick, WA to two kinds of buyers: contractors building drives, pads and drainage, and homeowners patching a path or a side yard. Both work the same ground, so both start with 5/8 minus.

This is windblown loess country across the Columbia Basin and the Yakima Valley. The silt is dry and loose, and it sheds water instead of soaking it up.

Ground and Conditions in Kennewick

When a path or drive fails here, it usually fails because the base under it was too thin to spread the load. The surface rock stays put; the silt beneath it pumps and shifts.

The fix is a proper granular course, not a thicker skim of the same thing. On soft ground, 1 1/4 minus goes down first to carry the weight.

Drainage matters too. Parts of this region take only seven to nine inches of rain a year, so the ground stays dry and loose.

When a thunderstorm or a rapid thaw does arrive, that silt sheds the water rather than absorbing it, and short violent runoff cuts rills and gullies in bare ground.

A washed stone layer under a path or a downspout gives that water somewhere to go. Where flood gravel sits at the surface, water disappears straight down instead.

Timing is worth planning around. The wet weather season for erosion control runs October 1 through June 30, and once snow falls or the ground freezes, placing and compacting base material stops being practical.

Materials for Kennewick Projects

Fines and screenings do the detail work on paths and walkways here. They pack down tight underfoot because the crusher fines are still in the mix, so a walkway surface stays firm instead of rolling under a wheelbarrow.

Walkway Gravel, sold locally as 1/4 minus or quarter minus, is the fine end of the minus range. It suits garden paths, side yards and any surface that needs to feel solid.

Stone Screenings, called crusher dust or 3/8 minus, beds pavers and flagstone and fills the joints between them. It compacts rather than drains, which is exactly what a setting bed needs.

For the base beneath those surfaces, 5/8 Minus is the Washington default. It is crushed rock with the fines left in, known locally as 5/8 minus or CSTC, and it packs hard and sheds water rather than soaking it up.

Where a path sits on soft or wet ground, 1 1/4 Minus goes underneath. Also called CSBC, it has a larger top size and fewer fines, so it carries load while staying workable.

Where you want water to move instead of stopping, 3/8" Crushed Stone is the washed counterpart. It is fines-free and suits permeable paver joints and small drain runs.

Delivery to Kennewick and the Surrounding Area

You order online and a dump truck tips your material on site. Quantities are ordered by the ton or by the yard, and each product page has a calculator to help you size the load.

Kennewick sits in Benton County, and delivery covers the city and the surrounding area, including Richland, West Richland, Prosser and Benton City.

Have the drop spot clear before the truck arrives. The load lands in one pile, so pick a spot that keeps the material out of the way of the work.

Questions About Gravel and Stone in Kennewick

What should I have ready when the truck arrives?

Have the drop spot clear and reachable, with nothing in the way of the truck. The load is tipped in one pile, so choose a spot that suits how you will move the material.

Check overhead lines and any low branches on the approach. If the ground is soft, pick a firm spot so the truck does not sink.

What is the best base under pavers in Kennewick?

Start with 5/8 minus as the structural course, then bed the pavers in crusher dust or 3/8 minus. The screenings compact, so they hold the pavers steady while the minus course below carries the load.

Where the silt under the path is soft or wet, put 1 1/4 minus down first.
