Bulk Gravel Delivery to Mohler, WA

If you are planning a driveway, a parking pad or a walkway out to a shop, gravel and aggregate delivery in Mohler, WA starts with the right base material. Washington Rock Supply delivers bulk loads across Lincoln County.

For most drives and pads, that material is 5/8 minus, the crushed surfacing top course local yards call CSTC. It packs hard and sheds water instead of soaking it up.

Ground and Conditions in Mohler

Across the Columbia Basin, Yakima Valley and the channeled scablands, the ground is windblown loess over Columbia River basalt. Where the Ice Age floods ran, the loess was stripped off and the basalt left bare.

That ground is dry and loose for much of the year. Parts of the basin take only seven to nine inches of rain a year, and when a thunderstorm or a rapid thaw does arrive, the silt sheds water rather than absorbing it.

A thin base shows its failure fast here. It rutts, pumps and loses its shape the first time water runs across it.

The fix is a structural course under the surface course. Place 1 1/4 minus, the crushed surfacing base course or CSBC, below your 5/8 minus top.

Where flood gravel sits at the surface, water disappears straight down instead. That is the ground you want under a drain run.

Timing matters too. Eastern Washington's 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.

Cold, dry winters here freeze the ground properly, so frost heave in an unbound base is something to design for. The county or city building department sets the footing depth figure.

Materials for Mohler Projects

Fines and screenings do the close work on paths, side yards and paver beds. These are the minus products: the crusher fines stay in, so the material compacts instead of draining.

Walkway Gravel, sold locally as 1/4 minus or quarter minus, is the fine end of that range. It packs down tight underfoot, which is what a garden path or side yard needs.

Stone Screenings, also called crusher dust or 3/8 minus, is the bedding material. Use it under pavers and flagstone and to fill the joints between them.

Where a path or paver bed needs to drain rather than compact, switch to a washed stone. 3/8" Crushed Stone is fines-free and works in paver joints and small drain runs.

For the drive itself, 5/8 Minus is the Washington default surfacing course, and 1 1/4 Minus is the base course beneath it. Long rural approaches and equipment parking often take Driveway Gravel instead.

Drainage runs take Drain Rock, known locally as 7/8 clean or washed rock. It has no fines, so it keeps the voids water needs.

Garden beds and play areas take Natural Pea Gravel, a rounded washed stone that will not compact. Edge it where it can wander.

Questions About Ordering in Mohler

What should I have ready when the truck arrives?

Have the drop spot clear and reachable, with no overhead lines or low branches in the way. The truck tips the load in one pile, so the spot you choose is where the material stays.

A firm, level surface helps the truck get in and out cleanly.

What is the best base under pavers in Mohler?

Start with 1 1/4 minus for the structural course, then bed the pavers in crusher dust or 3/8" Crushed Stone, depending on whether you want the bed to compact or drain. The fines-bearing material packs; the washed stone stays open.
