Materials for Moses Lake Projects

Base and driveway surfacing is where a Moses Lake project starts. The Washington default is 5/8 minus, also called crushed surfacing top course or CSTC.

It is crushed rock with the fines left in, so it compacts into a tight surface and water runs off rather than sitting in it.

Under that top course goes 1 1/4 Minus, the crushed surfacing base course, or CSBC. It has a larger top size and fewer fines, so it carries load and stays workable on soft, wet ground.

For a long rural drive, farm approach or equipment parking, Driveway Gravel is sold as a blend alongside the graded surfacing courses. Walkway Gravel, or 1/4 minus, is the fine end of the minus range and packs down tight underfoot for paths and side yards.

Washed stone is the other half of the split. Minus material holds water out; clean stone lets it through.

• Drain Rock, also called 7/8 clean, is washed with no fines, so it keeps its voids in footing drains, French drains and infiltration trenches.
• 3/4" Crushed Stone is the washed counterpart to a minus product, used for trench backfill, pipe surround and drain fields.
• Stone Screenings, or crusher dust, is a minus product that compacts rather than drains, which suits paver and flagstone bedding.

Sand and soil round out a site. Washed Sand goes into concrete mixes, paver setting beds and pipe bedding, washed so silt does not throw the mix off.

Mason Sand is the finer grade for mortar, stucco and joint sweeping.

To raise grade or backfill an over-excavation before a granular course goes down, Fill Dirt is the material.

Top Soil is screened and blended for lawn repair, new turf and grading out settlement.

For beds and features, Washington River Rock is rounded stone for dry creek beds and downspout splash pads, and Natural Pea Gravel is washed and rounded for play areas, dog runs and planting beds.

Ground and Conditions in Moses Lake

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.

Water here comes as scarcity and then too much at once. Parts of the basin take only seven to nine inches of rain a year, so the ground is dry and loose.

When a thunderstorm or a rapid thaw arrives, the silt sheds water rather than absorbing it.

That is the reason a compacted minus course matters. A fines-bearing surface sheds runoff instead of soaking it up, and where flood gravel sits at the surface, water disappears straight down instead.

Wind off bare, dry silt moves soil, and short violent runoff cuts rills and gullies when a cloudburst or a thaw lands on ground with no cover. Irrigation runoff moves soil too.

The working season is long either side of a hard winter. 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.

Winters here are cold and dry, and the ground freezes properly, unlike west of the Cascades. Frost heave in an unbound base is something to design for.

The building department sets footing depth, and it runs deeper with elevation.
