Bulk Material Delivery in Aurora, OR

Oregon Rock Supply handles gravel and aggregate delivery in Aurora, OR, and the ground here shapes what you order. Much of the valley floor is deep silt laid down by the ice-age floods, and that silt sheds winter water slowly.

3/4 minus is the base that goes under drives and pads here. It is graded 3/4 inch down to fines, so it compacts and locks up instead of staying loose.

Materials for Aurora Projects

Washed stone does the drainage work on this ground. Water that cannot pass through silt needs somewhere to go, and a French drain, drywell or downspout run gives it that path.

Washed material is screened free of fines so water moves through the voids instead of sitting in them.

Drain Rock is the round, washed stone for French drains, curtain drains, footing drains and drywells. It stays open, so a trench filled with it carries water away rather than holding it.

3/4" Crushed Stone, sold locally as 3/4 clean or 3/4 open, is angular rock with the fines screened out. Use it in drainage trenches, behind retaining walls and on construction entrances.

Washed Sand beds pipes and levels under slabs. It is washed so it drains instead of holding water, which matters in ground that already stays wet.

For the base course under that drainage work, 3/4 Minus is the standard under driveways, parking pads, shop floors and shed bases across this part of Oregon. It compacts because it keeps its fines.

On the finer end, 1/4 Minus beds pavers and flagstone, tops a compacted base and fine grades paths. 3/8" Natural Pea Gravel suits paths, play areas and dog runs where a smooth rounded stone is wanted.

Ground and Conditions in Aurora

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, so the ground stays soft long after the rain stops.

That is why drainage and timing both matter here. A base course over saturated subgrade will not hold, and a trench that fills with fines will not carry water away.

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 season for that reason.

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

What gravel is best for a driveway in Aurora?

On most drives here, a minus rock that compacts is the right surface, and 3/4 minus is the standard base under driveways and parking pads in this part of Oregon. A clean or open rock has the fines screened out, so it drains but rolls underfoot.

For a drive, use a material that locks up.
