Riprap and Bulk Aggregates for Imnaha, OR

If you need gravel and aggregate delivery in Imnaha, OR, the first question is usually which stone holds a bank or a swale without washing out. Oregon Rock Supply delivers bulk rock, 3/4 minus, sand and soil across Wallowa County.

In the Blue Mountains and Wallowas, snowmelt off the high ranges is the event that moves ground.

Coarse stone is the answer for slope, swale and bank protection here, and finer material covers the flatwork and beds behind it.

Materials for Imnaha Projects

Spring runoff scours stream banks and culvert outlets across the Blue Mountains and Wallowas, so the coarsest stone does the protecting. RipRap is the material for armoring banks, pond edges and cut slopes.

Oregon riprap is specified by class, from Class 50 up to Class 2000.

Railroad Ballast is coarse angular rock for heavy hard standing and severe drainage. #4 Crushed Stone handles trench bottoms and construction entrances, and Oregon yards more often sell this size as 1 1/2 clean.

Water still has to move somewhere. Drain Rock is washed and open for French drains, footing drains and drywells, so water passes through instead of sitting.

3/4" Crushed Stone is angular rock with the fines screened out, good for drainage trenches and retaining wall backfill.

Finishing a surface is a different job from protecting a slope. 3/4 Minus is the standard Oregon base under driveways, parking pads and shed bases, graded 3/4 inch down to fines so it compacts and locks up.

Ground and Conditions in Imnaha

The working season in the Blue Mountains and Wallowas is short, running between snowmelt and the first hard frosts. Frozen ground stops compaction through the winter, so timing a delivery matters as much as the material itself.

Across this part of the state, snowmelt is the main event. The high ranges take 50 to 80 inches of precipitation a year and feed valleys that get far less, which is why spring runoff scours stream banks, culverts and steep forest roads.

That runoff is the reason coarse stone leads here. RipRap and ballast hold a bank or a swale where finer material would move, and drain rock carries water away from footings and downspouts once it has been collected.

Wallowa County sets frost depth figures for its own area. If your project needs a footing depth, that number comes from the county, not from the material supplier.

Questions About Ordering Stone in Imnaha

What stone should I use for drainage in Imnaha?

Use washed, open stone. Drain Rock is the choice for French drains, footing drains, drywells and downspout runs because the fines are washed out and water moves through it.

For drainage trenches and retaining wall backfill, 3/4" Crushed Stone is angular rock with the fines screened out. Oregon yards may specify these sizes as clean or open rock, or by numbered designations such as #57 Stone.

What should I have ready when the truck arrives?

Have a clear, firm place for the pile. The truck tips the load in one pile on site and does not spread or place it, so the spot you choose is where the material stays until you move it.

Order your quantity by the ton or yard beforehand and pick your delivery date at checkout, then make sure the route in is passable.
