Bulk Gravel Delivery to Pomeroy, WA

Washington Rock Supply handles gravel and aggregate delivery in Pomeroy, WA for driveways, shop pads and drainage work. Most of that work starts with 5/8 minus, the crushed surfacing top course that packs hard because the fines stay in it.

The ground here is deep windblown silt, fine and easily worked, and it moves when water runs across it. That shapes what you put on top.

Ground and Conditions in Pomeroy

Across the Palouse and the Blue Mountain foothills, the soil is loess: fine windblown silt, piled deep and easy to dig. It is also easy to move once water gets to it.

A thin base over that ground shows its weakness fast. The surface stays flat while the silt underneath squeezes sideways, and the driveway starts to rut and pothole.

Sheet and rill erosion on long cultivated slopes is the same problem at field scale, driven by rain falling on frozen soil.

The fix is a structural course that spreads load instead of punching into the silt. That means 1 1/4 minus, also specified as crushed surfacing base course or CSBC, under a 5/8 minus top course.

Timing matters too. The working season runs long and dry through summer and closes when the ground freezes.

The worst risk is not high summer but the thaw, when the top inch thaws over frozen soil below and rain and snowmelt run across the surface.

Frost depth is set by the county or city building department. Confirm the local number before you plan footings or slab edges.

Materials for Pomeroy Projects

Bedding is where a lot of flatwork succeeds or fails. Pavers, flagstone and slabs sit on material that compacts, not material that drains, because a bedding course needs to hold its shape under the unit.

For that, Stone Screenings, also called crusher dust or 3/8 minus, is the fine end of the minus range and packs down tight. It is what you bed pavers and flagstone on and sweep into the joints.

5/8 minus, the crushed surfacing top course, is the Washington default surfacing course for driveways, parking pads and shed or shop slabs. Crushed rock with the fines left in, it packs hard and sheds water instead of soaking it up.

Underneath, 1 1/4 Minus, or crushed surfacing base course, carries the load. It has a larger top size and fewer fines than 5/8 minus, so it stays workable on soft wet ground.

Where water has to leave, the clean side of the yard takes over. Drain Rock, also called 7/8 clean, is washed with no fines, so it keeps its voids in footing drains and French drains.

For paths and side yards, Walkway Gravel, or 1/4 minus, is fine enough to pack tight underfoot. Rounded stone such as Washington River Rock goes in dry creek beds and splash pads, where it stays loose by design.

Sand rounds out the order. Washed Sand, also called washed concrete sand, is washed to take the silt out, which matters on a site working through the wet season.

Mason Sand handles mortar, stucco and paver joint sweeping.
