Railroad Ballast and Bulk Aggregates for Asotin, WA

Washington Rock Supply handles gravel and aggregate delivery in Asotin, WA, by the ton or by the yard. Start with 5/8 minus if you are surfacing a drive or a parking pad.

This corner of the state drains badly in late winter. Water that cannot get in runs across the surface instead, so stone that moves water matters here.

Materials for Asotin Projects

Slope, swale and bank protection starts with coarse stone. Water leaving a cut slope or a ditch needs something heavy enough to stay put when the thaw sends it running.

RipRap armours shorelines, streambanks, culvert outfalls and cut slopes.

Large River Rock is the 2 to 8 inch round stone for swale and ditch armour, bank toes and culvert outfalls. Rounded stone sheds flow instead of locking together, so keep it for armour rather than a base.

Railroad Ballast is track rock for rail spurs, yard track and heavy equipment pads. Always ask for it in full.

Drain Rock, also called 7/8 clean, is washed with no fines. That keeps its voids open in footing drains, French drains and infiltration trenches.

5/8 Minus is the Washington default surfacing course, sold locally as crushed surfacing top course, or CSTC. The fines stay in, so it packs hard and sheds water instead of soaking it up.

Ground and Conditions in Asotin

Eastern Washington's wet weather season runs October 1 through June 30. The working season is long and dry through summer and closes when the ground freezes.

The worst erosion risk is not high summer. It is the thaw, when warm rain falls on frozen or part-thawed ground.

Across the Palouse and the Blue Mountain foothills, the ground is loess, windblown silt piled into rolling hills. It is fine, deep and easily worked, and it moves easily too.

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.

Anything built on a slope here needs runoff routed before it starts cutting. That is where coarse stone earns its place, and where a washed product beats a minus one.

Frost depth is set by the county or city building department. Confirm the local number before you plan footings.

Questions About Stone in Asotin

What stone should I use for drainage in Asotin?

Use a washed, fines-free stone so the voids stay open. Drain Rock, also called 7/8 clean, suits footing drains, French drains and infiltration trenches.

For trench backfill and pipe surround, 3/4" Crushed Stone drains instead of compacting. Where a drywell or heavy drainage is going in, #4 Crushed Stone is the larger clean size for that work.

What should I have ready when the truck arrives?

Have the drop spot clear and reachable, with nothing overhead and nothing in the way of a turning truck. The driver tips the load in one pile, so the ground you choose is where the material stays.
