Railroad Ballast and Bulk Aggregates for Creston, WA

If your question is which stone holds a slope or a bank above a swale, gravel and aggregate delivery in Creston, WA starts with size. Washington Rock Supply sells bulk material by the ton for drives, drainage and slope work.

For a hard packed surface, 5/8 minus is the local default. Windblown loess sits deep across this part of the Columbia Basin, and when a cloudburst lands on bare silt, water runs instead of soaking in.

Materials for Creston Projects

Slope, swale and bank protection starts coarse. Rounded and washed stone is not what armours a bank, and fines-bearing rock is not what drains one.

Match the size to the job.

Riprap is the heavy answer for shorelines, streambanks, culvert outfalls and cut slopes.

Large round rock, also called 2 to 8 inch round or cobble, is the mid-size armour for swales, ditch lines, bank toes and culvert outfalls. Rounded stone moves where a smaller size would be carried off in a winter storm.

Drain rock, also called 7/8 clean or washed rock, is washed with no fines, so it keeps its voids and moves water instead of holding it. Use it for footing drains, French drains and infiltration trenches.

Railroad ballast is the heavy angular rock for rail spurs, yard track and equipment pads. Say railroad ballast in full.

Once the slope work is done, the surfacing sizes take over. 5/8 minus is crushed rock with the fines left in, so it packs hard, and 1 1/4 minus sits below it as the structural course on soft ground.

Ground and Conditions in Creston

Plan around the working season first. Eastern Washington's wet weather season for erosion control runs October 1 through June 30, and snow or frozen ground ends placing and compacting base material.

Across the Columbia Basin, Yakima Valley and the channeled scablands, winters are cold and dry and the ground freezes properly. Frost heave in an unbound base is something to design for.

The soil here is windblown loess over Columbia River basalt. Where the Ice Age floods ran, that silt was stripped off and the basalt left bare.

Parts of this region take only seven to nine inches of rain a year, so the ground stays dry and loose. When a thunderstorm or a rapid thaw does arrive, silt sheds the water rather than absorbing it.

Where flood gravel sits at the surface, water disappears straight down instead. That difference decides whether a bank needs armour or a drain.
