Crushed Stone, Sand and Gravel in Union, OR

Gravel and aggregate delivery in Union, OR runs on a short season. Snowmelt feeds the valleys off the Blue Mountains and Wallowas, and the ground has to be workable before a truck tips a load.

Oregon Rock Supply delivers 3/4 minus and the rest of the yard by the ton.

Plan your base and driveway work between snowmelt and the first hard frosts. Frozen ground stops compaction through the winter.

Materials for Union Projects

Base and driveway surfacing is where most Union ground work starts. The base rock here is 3/4 minus, also called 3/4-0 or dense-graded base rock.

It is crushed rock graded from 3/4 inch down to fines, so it compacts and locks up under a drive, a parking pad, a shop floor or a shed base.

3/4 Minus is the standard Oregon base. Under it, Quarry Run is raw rock straight from the pit face, uncrushed, used to build up soft ground and raise grade before a graded base goes on.

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

Washed stone is the other half of the work. Drain Rock, also called 1 1/2 clean, is washed and open so water moves through it instead of sitting.

It goes in French drains, footing drains, drywells and downspout runs.

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

RipRap is the large stone for armoring stream banks, culvert outlets and cut slopes.

Sand and soil round out a site. Washed Sand beds pipe and levels under flatwork, and it drains instead of holding water.

Top Soil is screened for lawns and bed prep, and Fill Dirt raises grade before a base course goes on.

For beds and paths, 3/8" Natural Pea Gravel is a smooth rounded stone for paths and dog runs. Willamette River Rock is water-worn stone for decorative beds, borders and dry creek beds, and Shredded Mulch is the bark dust Oregon customers ask for by name.

Ground and Conditions in Union

Water is the driver in this part of the state. Snowmelt is the main event, and the high ranges take far more precipitation than the valleys below them.

That melt has to go somewhere.

Across the Blue Mountains and Wallowas, spring snowmelt scours stream banks and culverts. Runoff comes off steep forest roads, and bare slopes after wildfire shed water fast.

Ground that sat wet all spring does not compact, so timing matters as much as material.

The ground itself is old and mixed. Accreted terranes with granitic intrusions sit under Columbia River Basalt, with volcanic ash caps on the forested slopes and alluvial gravel in the valleys.

Silt and clay show up in valley ground and clod up when wet.

Frost depths in this zone run 18 inches from 2,500 to 4,000 feet and 24 inches at 4,000 feet and above, a figure the county sets. It is the number a building official uses for footings.
