Riprap and Bulk Aggregates for Tygh Valley, OR

Oregon Rock Supply offers gravel and aggregate delivery in Tygh Valley, OR. The base most drives, pads and shop floors start from here is 3/4 minus, a crushed rock graded 3/4 inch down to fines so it compacts and locks up.

Ground in this part of the state is basalt under wind-laid loess. That silt turns greasy when wet and sheds water fast when dry, so what you put on top matters.

Materials for Tygh Valley Projects

Slope, swale and bank protection is the work that sets this area apart. Winter runoff off frozen ground moves fast, and the fix is coarse, open stone that lets water through instead of stone that washes out.

Riprap is the starting point for armoring. It is specified locally by class, from Class 50 up to Class 2000, so match the class to the bank and the flow it sees.

Large River Rock handles splash pads under downspouts and heavier decorative and bank work where small stone would wash out.

Railroad Ballast is coarse angular rock for heavy hard standing and severe drainage where a large open stone is wanted. #4 Crushed Stone covers construction entrances, trench bottoms and heavy drainage, and most Oregon yards sell that size as 1 1/2 clean.

Below the coarse end, Drain Rock is washed and open for French drains, footing drains, drywells and downspout runs. Water moves through it instead of sitting.

For a compacted base, 3/4 Minus is the standard under driveways, parking pads and shed bases. 1/4 Minus beds pavers and flagstone and tops a compacted base.

Ground and Conditions in Tygh Valley

Across the Columbia River Gorge and Plateau, precipitation runs about 8 to 15 inches a year. The trouble is not volume.

It is loess that turns greasy when wet, sheds water fast when dry, and runs off frozen ground in winter.

That shapes the working season. Hard frost sits at one end and summer dust at the other, and water for compaction usually has to be hauled onto the plateau.

Wind on bare loess, rill and gully cutting on cultivated slopes, and sudden runoff in dry draws during summer thunderstorms are the erosion drivers. Coarse stone on banks and swales is how you answer all three.

Winters here run colder than the elevation steps suggest, so confirm any frost figure with the Wasco County building department before you set a footing depth.

Questions About Stone in Tygh Valley

What stone should I use for drainage in Tygh Valley?

Drain Rock is washed and open, so water passes through instead of sitting in the trench. For a French drain, footing drain or drywell, that is the material.

Where you need angular stone with the fines screened out, use 3/4 clean for drainage trenches and retaining wall backfill. Both stay open.

A minus rock does the opposite job: it compacts into a base.

What should I have ready when the truck arrives?

Have the drop spot clear and reachable, and know where you want the pile. The truck tips the load in one pile, so pick a spot that keeps it out of the way of your work.
