Pea Gravel, Stone and Soil Delivery in Prineville, OR

If you are pricing gravel and aggregate delivery in Prineville, OR, the first question is usually which rock the job actually needs. Oregon Rock Supply sells 3/4 minus, washed stone, sand, soil and decorative rock in bulk, delivered by the ton.

Prineville sits on the dry side of the state, where the ground drains fast and the work is often about moving water away from a structure rather than holding it back.

Materials for Prineville Projects

Drainage is the job that shapes a lot of orders here. French drains, drywells and downspout runs all need washed stone, which is screened free of fines so water passes through instead of pooling.

Drain Rock is the washed, rounded stone for French drains, curtain drains, footing drains, drywells and downspout runs. Because it is open, water moves through the void spaces rather than sitting in the trench.

3/4" Crushed Stone, also called 3/4 clean or 3/4 open, is angular rock with the fines screened out. Use it in drainage trenches, behind retaining walls, on construction entrances and to bridge soft, wet ground.

3/8" Crushed Stone is the smaller clean stone for pipe bedding and tight drainage work. Washed Sand beds pipes and levels under slabs because it drains rather than holding water.

Where a surface has to lock up and stay put, the minus materials do that work. 3/4 Minus, also called 3/4-0, is crushed rock graded from 3/4 inch down to fines, and it compacts into a firm base under driveways, parking pads, shop floors and shed bases.

1/4 Minus, or quarter minus, is the fines product for bedding pavers and flagstone, topping a compacted base and fine grading on paths. Driveway Gravel surfaces an existing drive or tops a compacted base.

For decorative beds and dry creek beds, 3/8" Natural Pea Gravel suits paths, play areas and dog runs, while Willamette River Rock and Large River Rock handle borders, splash pads under downspouts and heavier bank work.

Delivery to Prineville and the Surrounding Area

Oregon Rock Supply delivers bulk material across Prineville and Crook County, including Paulina, Post and Powell Butte. You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout.

Each product page has a calculator if you want to size the load before you order. A dump truck then tips the material on site as a single pile, so it helps to know where that pile should sit before the truck arrives.

Ground preparation is worth thinking about at the same time as the order. Fill Dirt and Quarry Run both build up grade before a graded base course goes on top, and both are ordered the same way.

Ground and Conditions in Prineville

This part of Oregon is young volcanic ground. Across Central Oregon and the High Lava Plains, basalt sits under pumice, cinder and ash soils, with thin soil over hard rock along the rims.

Precipitation runs about 8 to 12 inches a year, and pumice and fractured basalt drain very fast. The usual problem is holding enough moisture for compaction, not shedding water.

That shapes the working season. The long dry stretch from late spring into autumn is cut short at both ends by hard frost, and summer compaction normally needs added water.

Wind moves bare pumice and ash, and short intense summer thunderstorms cut channels in dry draws. Erosion control on exposed ground is worth planning before the season turns.

Winters here are cold and clear with wide day-to-night swings and repeated freeze-thaw. Frost depth figures are published by county and elevation, and the county building official sets the figure that applies to a given site.
