Buy 1/4 Minus in Damascus, OR

Oregon Rock Supply handles gravel and aggregate delivery in Damascus, OR for two kinds of buyers: contractors building drives and pads, and homeowners fixing a muddy lane or a worn path. Both usually start with 3/4 minus, the dense-graded base rock that compacts and locks up under a driveway.

This corner of Clackamas County sits on deep silt and clay loam that sheds winter rain slowly, so what goes under a surface matters as much as the surface itself.

Materials for Damascus Projects

Base and driveway surfacing is where most ground work here begins. 3/4 Minus, also called 3/4-0 or 3/4 inch minus, is crushed rock graded from 3/4 inch down to fines.

It compacts into a firm, tight layer under driveways, parking pads, shop floors and shed bases.

Driveway Gravel surfaces an existing drive or tops a compacted base. On a Damascus drive that means a minus rock that will compact rather than a clean rock that rolls underfoot.

Where the ground is soft or low, Quarry Run builds up grade before a graded base course goes on top. It is raw rock straight from the pit face, not crushed and screened material.

Water is the other half of the job. Drain Rock, sold locally as 1 1/2 clean or washed drain rock, is washed and open so water moves through it instead of sitting.

It suits French drains, footing drains, drywells and downspout runs.

3/4" Crushed Stone, or 3/4 clean, is angular rock with the fines screened out. It goes in drainage trenches, behind retaining walls and under construction entrances.

For finishing work, 1/4 Minus (quarter minus) beds pavers and flagstone and tops a compacted base. Washed Sand beds pipe and levels under flatwork, and Top Soil is screened for lawns and bed prep.

Decorative work runs on rounded stone: 3/8" Natural Pea Gravel for paths and play areas, and Willamette River Rock for beds, borders and dry creek beds.

Ground and Conditions in Damascus

Across the Willamette Valley and Portland Basin, 35 to 45 inches of rain falls almost entirely between November and March. It lands on tight silt and clay that sheds water slowly, and the lowlands carry a seasonal high water table.

That combination decides how a Damascus base is built. A fines-bearing rock like 3/4 minus compacts and locks up, but it holds water rather than passing it.

Where the subgrade stays soft through winter, a clean open stone below the base gives the water somewhere to go.

Winter rain also runs off bare silt and scours banks and cut slopes. Riprap is specified by class in Oregon, and it armors culvert outlets, pond edges and stream banks against that runoff.

Timing follows the season. Portland treats October 1 to April 30 as the wet weather season, when bare ground must be stabilized within two days, against seven days from May 1 to September 30.

Base and paving work concentrates in the dry months.

Frost is a minor factor here next to winter saturation and soft subgrade. The Oregon frost depth figure below about 2,500 feet is 12 inches, and the county sets it for footing work.
