Fill Dirt Delivery for Klickitat, WA

Washington Rock Supply handles gravel and aggregate delivery in Klickitat, WA. The local default surfacing course here is 5/8 minus, also called crushed surfacing top course.

It is crushed rock with the fines left in, so it packs hard and sheds water. On a site where the silt sits deep, that matters.

Materials for Klickitat Projects

Raising grade and building pads drive a lot of work here. Start with what you are building and work up from there.

For a driveway, your structural course is 1 1/4 minus, also called crushed surfacing base course or CSBC. It goes below a 5/8 minus top course and carries load on soft ground.

Then cap it with 5/8 minus for the driving surface. The fines let it pack tight and shed water.

For a patio or paver area, bed the pavers on crusher dust, also called 3/8 minus or screenings. It is a minus product, so it compacts rather than drains.

For a drainage run, use drain rock, also called 7/8 clean or washed rock. It is washed with no fines, so it keeps its voids and water moves through it.

For building up a low spot before any granular course goes down, use fill dirt, also called common borrow or unscreened fill.

Ground and Conditions in Klickitat

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, that silt was stripped and the basalt left bare.

In this part of the state, the silt sheds water rather than absorbing it. An under-built base on that ground moves when it gets wet.

Parts of the basin take only seven to nine inches of rain a year. When a thunderstorm or a rapid thaw does arrive, the runoff cuts rills and gullies in bare loess.

Where flood gravel is at the surface, water disappears straight down instead. That is where a drainage layer earns its place under a pad.

The working season here is long either side of a hard winter. Once snow falls or the ground freezes, placing and compacting base material stops being practical.

The ground also freezes properly here, unlike west of the Cascades, so frost heave in an unbound base is something to design for. Frost depth is set by the county or city building department and runs deeper with elevation.
