Bulk Aggregates for Patios in Lamont, WA

Washington Rock Supply handles gravel and aggregate delivery in Lamont, WA, and the working season sets the schedule. Eastern Washington's wet weather season runs October 1 through June 30, so summer is the long dry stretch for moving material.

Start with 5/8 minus, the crushed surfacing top course this market builds on.

The ground here rewards timing. Loess covers the Palouse hills, fine windblown silt that is deep, easily worked, and easily moved once water gets under it.

Ground and Conditions in Lamont

Across the Palouse, water that cannot get in does the damage. When the top inch of loess thaws over frozen soil below, rain and snowmelt run across the surface instead of soaking in.

Under a paver patio or a flatwork slab, that runoff finds the weak point fast. A base that does not drain holds the water, and the fines in the bedding turn soft under it.

The surface above starts to rock and settle.

Crusher dust, also called screenings or 3/8 minus, is the standard bedding for pavers and flagstone. It is a minus product, so it compacts rather than drains, which is what you want directly under the stone.

Where water needs to move instead of sit, washed material does the job. Drain rock, or 7/8 clean, keeps its voids open under the bedding so a perched water table has somewhere to go.

Erosion is a related concern on long slopes here. Sheet and rill erosion of loess is driven by rain falling on frozen soil, and the basin has lost topsoil steadily since farming began.

Materials for Lamont Projects

Bedding under pavers and flatwork is where these projects are won or lost, so the material under the stone matters more than the finish. Screenings compact tight and hold a setting bed.

Around that, you need a structural course and a clean layer for drainage.

Local terms matter on an order sheet. Ask for 5/8 minus, 1 1/4 minus, crusher dust, or drain rock and you will get the material this market means.

For the layer beneath a patio, 1 1/4 minus is the base course. Larger top size and fewer fines than 5/8 minus, so it carries load and stays workable on soft wet ground.

Where a joint or a setting bed needs washed, fines-free stone, 3/8 clean fits. It drains instead of compacting, which is the opposite of what screenings do.

For a base that spreads across a long drive, 5/8 minus is the default. Crushed rock with the fines left in packs hard and sheds water instead of soaking it up.
