Bulk Material Delivery in Jefferson, OR

Winter rain here lands on tight silt and clay that sheds water slowly. That is why gravel and aggregate delivery in Jefferson, OR starts with drainage stone, not with a base rock.

Oregon Rock Supply delivers bulk 3/4 minus, washed stone, sand and soil by the ton. Order online, pick a date, and a dump truck tips the load on site.

Materials for Jefferson Projects

Start with the washed stone. Rain that falls between November and March has to go somewhere, and open rock gives it a path down and away instead of a place to sit.

Drain Rock is washed and open, so water moves through it. Use it in French drains, curtain drains, footing drains, drywells and downspout runs.

3/4" Crushed Stone is angular rock with the fines screened out. It goes in drainage trenches, retaining wall backfill, construction entrances and soft wet ground that needs bridging.

3/8" Crushed Stone is the small angular size for pipe bedding and tight drainage work.

Then the base rock. 3/4 Minus, also called 3/4-0 or dense-graded base rock, is crushed rock graded 3/4 inch down to fines.

It compacts and locks up under driveways, parking pads, shop floors and shed bases.

Quarry Run is raw rock straight from the pit face. It builds up soft ground and raises grade before a graded base course goes on top.

Finer material finishes the work. 1/4 Minus, or quarter minus, beds pavers and flagstone, tops a compacted base and fine grades paths.

Ground and Conditions in Jefferson

Across the Willamette Valley and Portland Basin, the ground is deep silt on the valley floor and silty clay loam in the foothills. Both shed water slowly.

Rainfall runs 35 to 45 inches a year, almost all of it between November and March, with a seasonal high water table in the lowlands. Saturated ground loses its strength long before it freezes.

That shapes the working season. Portland treats October 1 to April 30 as the wet weather season and requires bare ground stabilized within two days, against seven days from May 1 to September 30.

Base and paving work concentrates in the dry months.

Plan a delivery around that window. Dry ground compacts and holds grade; wet silt and clay pump and rut under a truck and a plate.

Frost is a minor problem here next to winter saturation. The 12 inch frost depth is the Oregon figure below about 2,500 feet, and the county sets it.

Erosion follows the same pattern. Winter rain runs off bare silt, scours banks and moves soil on steep slopes, so bare ground needs cover before the wet season starts.
