Bulk Material Delivery in Willamina, OR

Winter rain is what shapes gravel and aggregate delivery in Willamina, OR. Across the Willamette Valley, 35 to 45 inches falls almost entirely between November and March onto tight silt and clay that sheds water slowly.

Oregon Rock Supply delivers bulk material to sites in Yamhill County. For a driveway or pad, start with 3/4 minus, the graded base that compacts and locks up.

Materials for Willamina Projects

Coarse stone does the heavy work on slopes, swales and banks. Winter runoff scours bare silt, so arm the ground that water crosses before you surface anything else.

RipRap is the stone for armoring stream banks, culvert outlets, pond edges and cut slopes. Oregon riprap is specified by class, from Class 50 up to Class 2000.

Large River Rock suits dry creek beds, splash pads under downspouts and heavier bank work where small stone would wash out. It is rounded river stone, not crushed quarry rock.

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

Drain Rock, often called 1 1/2 clean, is washed and open so water moves through it. It goes into French drains, curtain drains, footing drains, drywells and downspout runs.

3/4 Minus, also called 3/4-0, is crushed rock graded 3/4 inch down to fines. It is the standard base under driveways, parking pads, shop floors and shed bases.

Ground and Conditions in Willamina

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

That pushes base and paving work into the dry months. On the Willamette Valley and Portland Basin side, ground sits under deep slackwater silt on the valley floor and red clay and silty clay loam in the foothills.

Frost heave is a minor problem next to winter saturation and soft subgrade. The frost depth figure of 12 inches belongs to the Oregon rule below about 2,500 feet, which covers the valley floor, and the county sets it.

Wet silt and clay turn soft fast. Build up low ground with quarry run, also called pit run, before a graded base course goes on top.

Questions About Stone in Willamina

What stone should I use for drainage in Willamina?

Match the stone to the job. Drain Rock, sold as 1 1/2 clean, is washed and open for French drains, footing drains and drywells.

Use 3/4" Crushed Stone, or 3/4 clean, in drainage trenches, retaining wall backfill and construction entrances. For pipe bedding and tighter drainage work, 3/8" Crushed Stone works.

Where the ground is soft and wet, bridge it with 3/4 clean before you build anything over it.

What should I have ready when the truck arrives?

Have the delivery spot clear, open and reachable for a dump truck. The driver tips the load in one pile and nothing gets spread or placed, so pick the spot with that in mind.
