Bulk Gravel Delivery to North Plains, OR

Oregon Rock Supply brings gravel and aggregate delivery in North Plains, OR to driveways, drain runs and landscape beds. Winter rain arrives in November and stays through March, so most ground work here squeezes into the dry months.

That timing shapes what you order. A load of 3/4 minus placed before the wet season sets up under a drive or a shed pad instead of pumping when the silt underneath goes soft.

Ground and Conditions in North Plains

Across the Willamette Valley and Portland Basin, the ground runs to deep silt on the flats and silty clay loam in the foothills. Both shed water slowly.

Rain that falls between November and March tends to sit rather than soak away.

A thin base shows itself fast in that ground. The rock punches down into the soft subgrade, ruts appear along the wheel tracks, and the surface stops holding its shape.

The fix is enough compacted base to spread the load over the silt below it. A minus rock keeps its fines, so it knits together and carries weight instead of rolling.

A clean rock has no fines to bind it and will not do that job.

Frost is a minor concern here. Washington County sets a 12 inch frost depth for footings, well below the shallow freezes this area sees.

Saturation and soft subgrade cause far more trouble than heaving.

Portland treats October 1 to April 30 as the wet weather season. Bare ground has to be stabilized within two days in that window, against seven days from May 1 to September 30.

Base and paving work concentrates in the dry season for that reason.

Materials for North Plains Projects

Fines and screenings do the fine work on paths and walkways around North Plains. 1/4 Minus, also called quarter minus, is crushed fines that bed pavers and flagstone, top a compacted base and grade a path to a smooth finish.

Walkway Gravel covers garden paths and walkways that need a surface which stays put underfoot. A fines-bearing material like this locks up and walks well, which a clean open stone does not.

3/4 Minus is the standard Oregon base under driveways, parking pads, shop floors and shed bases. It is crushed rock graded from 3/4 inch down to fines, so it compacts and locks up under a plate or a roller.

For water, Drain Rock is washed and open, so it moves water through French drains, curtain drains, footing drains and downspout runs. 3/4" Crushed Stone is the angular, fines-free version for drainage trenches and retaining wall backfill.

Where the native silt is too tight to plant, Garden Soil fills raised beds and vegetable plots. Top Soil is screened for lawns and finish grading, and Shredded Mulch, which Oregon customers call bark dust, goes over beds and tree rings.

Questions About Ordering in North Plains

What should I have ready when the truck arrives?

Have the drop spot clear, open and reachable, with space for a dump truck to pull in and out. The load is tipped in one pile, so the ground should be firm enough to hold it.

Remove vehicles, trailers or equipment from the area beforehand. If the spot is tight, pick a wider one nearby.

What is the best base under pavers in North Plains?

3/4 minus is the standard Oregon base for paver work. It keeps its fines, so it compacts into a firm, locked layer that spreads load over the silt below.

Bed the pavers themselves on 1/4 minus, also called quarter minus, which gives a flat, fine setting layer. Both are crushed products, so they bind rather than roll.
