Crushed Stone, Sand and Gravel in Umatilla, OR

Planning gravel and aggregate delivery in Umatilla, OR starts with the job: a driveway, a shop pad, a drainage run or a garden bed. Oregon Rock Supply sells bulk material by the ton and delivers it across Umatilla County.

Most ground work here begins with 3/4 minus, the graded crushed rock that carries its fines and locks up under a vehicle. From there the choice is about water, planting or finish.

Materials for Umatilla Projects

Base and driveway surfacing is where a project gets its structure. 3/4 Minus, also called 3/4-0 or 3/4 inch minus, is crushed rock graded from 3/4 inch down to fines.

It compacts and locks up, which is what a driveway, parking pad, shop floor or shed base needs underneath it.

Where the ground is soft or low, Quarry Run goes down first. Quarry run, also called pit run, is raw rock straight from the pit face, used to build up grade before a graded base course goes on top.

Fill Dirt does the same job for bulk raising and backfill.

For the drive surface itself, Driveway Gravel tops an existing drive or a compacted base. On an Oregon drive that means a minus rock that compacts rather than a clean rock that rolls underfoot.

Water is the other half of the job. Drain Rock, also called 1 1/2 clean or washed drain rock, is washed and open so water moves through it instead of sitting.

It suits French drains, footing drains, drywells and downspout runs.

3/4" Crushed Stone, or 3/4 clean, is angular rock with the fines screened out. It works in drainage trenches, retaining wall backfill and construction entrances.

Smaller drainage and pipe bedding takes 3/8" Crushed Stone.

Sand and soil finish the list. Washed Sand beds pipe and levels under flatwork, while Top Soil and Garden Soil handle lawns, raised beds and planting areas where the native ground is too tight to plant into.

Ground and Conditions in Umatilla

Umatilla sits in the Columbia River Gorge and Plateau ground region, where Columbia River Basalt flows lie under wind-laid loess. Deep silt covers the wheat ground, and soil gets shallow where the basalt comes near the surface.

Precipitation across this part of the state runs about 8 to 15 inches a year, so volume is not the problem. The trouble is loess that turns greasy when wet, sheds water fast when dry, and runs off frozen ground in winter.

That shapes what goes under a drive or pad here. A fines-bearing base like 3/4 minus compacts and holds, but the water still has to leave, which is why an open washed stone belongs in a drain or a downspout run rather than a compacting base.

Erosion follows the same pattern. Wind moves bare loess, cultivated slopes cut rills and gullies, and summer thunderstorms send sudden runoff down dry draws.

Riprap is specified by class in Oregon, from Class 50 up to Class 2000, for armoring banks, culvert outlets and cut slopes.

The working season is long, bounded by hard frost at one end and summer dust at the other. Winters here run cold and dry with a hard east wind through the Gorge, and ground frost goes deeper than it does west of the Cascades.

Frost depth figures are set by the county building department, so confirm the number there before footing work.
