Gravel, Stone and Soil for Wallowa County, OR

You need gravel, stone and aggregate delivery in Wallowa County, OR, and you want to know which material to order. Oregon Rock Supply sells bulk gravel, crushed stone, sand, topsoil and fill online, delivered by the ton or by the yard.

Start with 3/4 minus if you are building a drive, a parking pad, a shop floor or a shed base.

This is country where snowmelt runs hard off the mountains each spring, so what you put under a slab or a driveway has to shed water and still lock up tight. That is a question of picking the right size, not the right brand.

Materials delivered in Wallowa County

Oregon names aggregate by top size. A minus rock keeps its fines and compacts.

Clean or open rock has the fines screened out and drains. Getting that pair right decides how a job performs.

3/4 minus, the base rock

Oregon specifies base material by top size with a minus notation. The Oregon Standard Specifications for Construction set dense-graded base aggregate in Section 02630.10, at 2 1/2 inch - 0 through 3/4 inch - 0, and Section 00641.10 states that base aggregate is dense-graded unless otherwise specified.

Section 02630.11 covers open-graded aggregate, the clean material with no fines.

3/4 minus is the standard Oregon base under driveways, parking pads, shop floors and shed bases. It is crushed rock graded 3/4 inch down to fines, so it compacts and locks up under a vehicle or a slab.

Clean and drainage rock

Drain rock and 3/4" Crushed Stone are washed and open, so water passes through instead of sitting against a footing. Use them for French drains, curtain drains, drywells and retaining wall backfill.

RipRap is the coarse class rock for armoring stream banks, culvert outlets and pond edges against winter runoff. Railroad Ballast is a larger open stone for track beds and heavy hard standing.

Fines, sand and soil

1/4 Minus beds pavers and flagstone and tops a compacted base. Washed Sand is washed so it drains, and it goes under slabs, around pipe and into concrete mix.

Garden Soil suits raised beds and vegetable plots where the native ground is too tight to plant into. Fill Dirt builds up low ground before a graded base goes on top.

Shredded Mulch, which Oregon customers call bark dust, goes on beds and tree rings.

Ground conditions across Wallowa County

This part of the state runs on snowmelt. The high ranges take 50 to 80 inches of precipitation a year and feed valleys that get far less, so spring water arrives fast and from above.

That shapes two things. Water needs somewhere to go under a drive or a footing, and slopes and stream banks take a beating as the melt scours them.

Bare ground after wildfire moves even more.

The working season is short, running from snowmelt to the first hard frosts. Frozen ground stops compaction through the winter, so timing a delivery matters as much as the material.

Some of the oldest rock in Oregon sits under this ground, with volcanic ash caps on the forested slopes and alluvial gravel in the valleys. That mix is why a fines-bearing minus rock compacts well here and a clean rock drains well here.

Choosing the right material

Union County and Baker County both sit in Eastern Oregon, on the same ground region as Wallowa County. Same old accreted rock, the same basalt over it, the same ash caps and valley gravel.

So the base and drainage choice does not change as you move between them. If 3/4 minus is the right compacting base for a driveway in Wallowa County, it is the right base on that same ground next door.

Pick by what the material has to do. Minus rock that keeps its fines for anything that must compact and carry.

Clean or open rock for anything that must move water. Rounded stone where you want a surface underfoot.
