Drain Rock and Bulk Aggregates for Prairie City, OR

Oregon Rock Supply delivers gravel and aggregate in Prairie City, OR by the ton. The base under most drives and pads here is 3/4 minus, a crushed rock graded 3/4 inch down to fines that compacts and locks up.

Snowmelt feeds the valleys across the Blue Mountains and Wallowas, so water has to have somewhere to go. Washed stone gives it that path.

Materials for Prairie City Projects

Water is the driver on most sites in this part of Grant County. Washed stone is screened free of fines, so it stays open and lets water move through instead of sitting.

That makes it the right material for French drains, drywells and downspout runs.

Start with the coarse end. Drain Rock, also called 1 1/2 clean, is round, washed and open.

It goes in French drains, curtain drains, footing drains and drywells.

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

For pipe bedding and tight drainage work, 3/8" Crushed Stone is a small angular rock that fits narrow trenches. Washed Sand beds pipe and levels under flatwork because it drains rather than holding water.

Then the compacting materials. 3/4 Minus is the standard Oregon base under driveways, parking pads and shop floors.

Quarry Run is raw rock straight from the pit face, used to build up soft ground before a graded base goes on.

RipRap armors stream banks, culvert outlets and pond edges against spring runoff. It is specified locally by class, from Class 50 up to Class 2000.

Ground and Conditions in Prairie City

This side of the state runs on a short season. Snowmelt comes off the high ranges, then the first hard frosts shut the ground down.

Frozen ground stops compaction through the winter.

That timing shapes when a base goes in. A graded base has to be worked while the ground is open, so a delivery date matters as much as the material itself.

The ground across the Blue Mountains and Wallowas is some of the oldest rock in Oregon, with alluvial gravel in the valleys. Spring snowmelt scours stream banks and culverts, and runoff off steep forest roads carries material downhill.

Grant County sets a frost depth of 18 inches from 2,500 to 4,000 feet and 24 inches at 4,000 feet and above. That figure belongs to the county, and it is a footing depth set by the building official.

Questions About Gravel in Prairie City

What gravel is best for a driveway in Prairie City?

On most Oregon drives the surface is a minus rock that compacts, and 3/4 minus is the standard base for that job. It is graded 3/4 inch down to fines, so it locks up under traffic instead of rolling underfoot.

A clean rock with the fines screened out stays loose and drains, which suits a drain rather than a drive.
