This is loess country. The windblown silt that settled across the Palouse and the Blue Mountain foothills is fine, deep and easily worked, and it moves when water hits it.

Ground and Conditions in Dixie

Start with the failure a thin base shows here. Set pavers or flatwork on too little stone and the loess underneath takes the load instead.

Silt fines pump up into the bedding, the surface rocks, and joints open. The fix is a base that carries the slab and a bedding course that stays put.

Water is the other half. When the top inch of loess thaws over frozen soil below, rain and snowmelt run across the surface instead of soaking in.

Every slope becomes a drainage path. Route runoff away from a patio edge before it starts cutting, and the base stays where you put it.

Eastern Washington's wet weather season runs October 1 through June 30. Summer is long and dry, so most ground work fits between the thaw and the freeze.

Frost depth is set by the county or city building department, so confirm the local figure before you plan footings.

Materials for Dixie Projects

Bedding and base choice decides whether a patio stays flat. The minus and clean split is the thing to get right: minus means the crusher fines stay in so the rock compacts and holds, clean means they are washed out so it drains.

For a paver or flagstone setting bed, crusher dust, also called 3/8 minus or screenings, is the fine end of the minus range. It packs under the stone instead of draining away from it.

Where you want a washed, fines-free bed, 3/8 clean does the job. It also fills paver joints and small drain runs.

Both sizes bed flatwork, and they behave differently once water arrives.

Under the bedding goes the structural course. 1 1/4 minus, also called CSBC or crushed surfacing base course, carries load and stays workable on soft wet ground.

Above it, 5/8 minus packs hard and sheds water rather than soaking it up.

For paths and side yards, 1/4 minus, also called pathway gravel, compacts tight underfoot. Round out a patio build with washed sand for the setting bed mix or mason sand for mortar and joint sweeping.

Questions from Dixie Buyers

What gravel is best for a driveway in Dixie?

Use 1 1/4 minus as the base course and 5/8 minus on top. The 1 1/4 minus, also called CSBC, carries load on soft ground, and the 5/8 minus, the crushed surfacing top course, packs hard and sheds water.

On a long rural drive, driveway gravel is the other common option.
