Bulk Material Delivery in Okanogan, WA

Snowmelt moves fast here. Gravel and aggregate delivery in Okanogan, WA starts with stone that can take that water and stay put.

Washington Rock Supply delivers bulk loads by the ton.

Start with 5/8 minus for drives and pads. Then step up to coarser stone where runoff scours a slope, a swale or a bank.

Materials for Okanogan Projects

Spring runoff cuts. It scours ditches, culverts and gravel roads during breakup, and it works on streambanks in the valley.

Coarse stone is what answers that.

Riprap is the heavy end of the range. Light and heavy loose grades armor shorelines, streambanks, culvert outfalls and cut slopes.

RipRap holds where moving water would carry smaller stone off.

Large round rock is the next size down. Rounded cobble from 2 to 8 inches armors swales, ditch lines, bank toes and culvert outfalls.

Large River Rock suits feature beds too.

Below that, 3/4 clean crushed rock is washed and fines-free. It drains instead of compacting, which fits trench backfill, pipe surround, drain fields and under-slab drainage.

3/4" Crushed Stone is the washed counterpart to a minus product.

Drain rock, also called 7/8 clean, keeps its voids. That matters where a perched water table sits on till.

Use it for footing drains, French drains and infiltration trenches. Drain Rock is washed with no fines.

For the surface itself, 5/8 minus is the Washington default. The crusher fines stay in, so it packs hard and sheds water instead of soaking it up.

5/8 Minus, or CSTC, goes on driveways, parking pads and shed slabs.

Under it, 1 1/4 minus carries load on soft wet ground. It sits below the top course on a drive, parking area or slab.

1 1/4 Minus is the CSBC base course.

Ground and Conditions in Okanogan

The season is short. Base, drive and paver work fits between spring breakup and the autumn freeze, and the window narrows the higher and further north the site sits.

Book the delivery date around that window, not after it. Eastern Washington's wet weather season for erosion control runs October 1 through June 30.

Ground frost governs any unbound base here. Frost depth is 24 inches in Okanogan County, set by the building department, and it can be deeper at elevation.

Across the Okanogan Highlands and the northeast corner, snowmelt arrives over a few weeks in spring. It saturates valley soils while the ground below is still frozen.

Gravel valley floors drain quickly; till and lake silt do not.

That is why a washed, fines-free stone belongs in a drain and a minus product belongs in a surface. Match the stone to the water it will meet.

Questions About Stone in Okanogan

What stone should I use for drainage in Okanogan?

Use a washed, fines-free stone. Drain rock, also called 7/8 clean, keeps its voids for footing drains, French drains and infiltration trenches.

For trench backfill and pipe surround, 3/4 clean crushed rock drains rather than compacts. Where a drywell or heavy drainage is involved, #4 Crushed Stone is the larger clean size.

Keep minus products out of a drain, because the fines fill the voids.

What should I have ready when the truck arrives?

A clear, reachable spot for the pile. The truck tips the load in one place, so the ground needs to be firm enough to take it and open enough to work around afterward.

Have your quantity settled before the delivery date you picked at checkout. Nothing else is needed from you on the day.
