Riprap and Bulk Aggregates for St. Paul, OR

Oregon Rock Supply offers gravel and aggregate delivery in St. Paul, OR, and the winter water is what sets the order here.

Rain lands on tight valley silt and clay that sheds it slowly. Coarse stone moves that water, and 3/4 minus builds the base under a drive or a pad.

Materials for St. Paul Projects

Slope, swale and bank protection starts with the coarsest stone, then works down to the fines that lock a surface up. Pick the size by what the ground has to do.

Riprap is the heavy answer on a cut slope or a scoured bank. Oregon riprap is specified by class, from Class 50 up to Class 2000, so the class follows the job the stone has to do.

Rounded river stone will not hold a slope the way angular riprap does.

Railroad ballast is coarse angular rock for track beds and severe drainage. It stays open, so water drops through instead of pooling on the surface.

Use it where a large open stone is wanted and the ground takes heavy loads.

Drain rock, also called washed drain rock or 1 1/2 clean, keeps water moving. It is washed and open, so it drains rather than sits.

Run it in French drains, curtain drains, footing drains, drywells and downspout runs.

For a drive or a pad, 3/4 minus is the standard Oregon base, also called 3/4-0 or dense-graded base rock. It is crushed rock graded 3/4 inch down to fines, so it compacts and locks up under a vehicle.

Driveway Gravel surfaces an existing drive or tops a compacted base.

Then the fine end. 1/4 minus, also called quarter minus or crushed fines, beds pavers and flagstone and grades paths.

Walkway Gravel gives a walkable surface that stays put underfoot. 3/8" Natural Pea Gravel suits paths and play areas, and Willamette River Rock works in decorative beds and dry creek beds.

Soils round out an order. Top Soil is screened for lawns and finish grading, Garden Soil fills raised beds and vegetable plots, and Fill Dirt raises grade before a base course goes on.

Ground and Conditions in St. Paul

Across the Willamette Valley and Portland Basin, 35 to 45 inches of rain falls a year, almost all of it between November and March. It lands on deep slackwater silt on the valley floor and on red clay and silty clay loam in the foothills.

Both shed water slowly, and the lowlands carry a seasonal high water table.

That timing shapes 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.

Base and paving work concentrates in the dry months, so plan a delivery date around the weather rather than against it.

Winter rain also drives the erosion. Runoff crosses bare silt, scours banks on the Willamette and its tributaries, and triggers slides on steep west hills and foothill slopes.

Riprap and open stone armor those edges, and drain rock carries the water away from a footing or a downspout.

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

Treat it as a footing depth, not a target for a gravel base.

Questions About Stone and Drainage in St. Paul

What stone should I use for drainage in St. Paul?

Match the stone to the water. Drain rock, also called washed drain rock or 1 1/2 clean, is washed and open, so it suits French drains, footing drains, drywells and downspout runs.

For a drainage trench, retaining wall backfill or a construction entrance, use 3/4 clean, an angular crushed rock with the fines screened out. Riprap handles bank and slope protection where runoff scours.

What should I have ready when the truck arrives?

Have the drop spot clear and reachable before the truck pulls in. The driver tips the load in one pile, so leave room for that pile and keep vehicles, bins and low wires out of the way.
