Crushed Stone, Sand and Gravel in Scappoose, OR

Oregon Rock Supply offers gravel and aggregate delivery in Scappoose, OR, from 3/4 minus for a compacted drive to garden soil for a raised bed. The ground across the Willamette Valley and Portland Basin runs to deep silt, so what you put on top of it matters.

Order by the ton or by the yard online, and a dump truck tips the load at your site.

Materials for Scappoose Projects

Grading and bed prep start with soil and fill, and that is where a Scappoose yard project usually begins. You strip or raise grade first, then bring in the material that finishes the surface.

Top Soil is screened for lawns, bed prep and finish grading. Screening matters here because valley ground is silty and clods up when it is wet.

Garden Soil is a blend for raised beds, vegetable plots and planting areas where native silt or clay is too tight to plant into.

Fill Dirt builds up low ground and backfills before a graded base course goes on top.

Under that finish work, 3/4 Minus is the standard Oregon base, crushed rock graded 3/4 inch down to fines so it compacts and locks up. It goes under driveways, parking pads, shop floors and shed bases.

Where water has to move instead of sit, Drain Rock is washed and open for French drains, footing drains, drywells and downspout runs. For a finer walkable surface, Walkway Gravel stays put underfoot on garden paths.

Ground and Conditions in Scappoose

This part of the state takes 35 to 45 inches of rain a year, almost all of it between November and March. That water lands on tight silt and clay that sheds it slowly, and the lowlands carry a seasonal high water table.

So the question on a Scappoose site is where the water goes once it leaves the roof and the drive. A compacted 3/4 minus base sheds it, and a washed stone layer under or beside the work gives it somewhere to drain.

Winter rain also runs off bare silt, scours banks on the Willamette and its tributaries, and moves soil on steep foothill slopes. Riprap is specified by class in Oregon, from Class 50 up to Class 2000, and armors stream banks, culvert outlets and pond edges against that runoff.

Timing follows the 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, so base and paving work concentrates in the dry months.

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