Order Gravel, Stone and Soil in Mulino, OR

Looking for gravel and aggregate delivery in Mulino, OR? Oregon Rock Supply drops bulk material at your address.

For a driveway or a shed pad, order 3/4 minus, the graded crushed rock that compacts and locks up under a vehicle. For beds and dry creek work, start with river rock.

Mulino sits in Clackamas County, on ground the ice-age floods laid down as deep silt across the Willamette Valley and Portland Basin. That silt is why a base has to be built right before anything goes on top of it.

Delivery to Mulino and the Surrounding Area

You order online: pick your material, choose a quantity by the ton or by the yard, and select a delivery date at checkout. Each product page has a calculator if you want help sizing the load.

A dump truck then tips the material in one pile at your Mulino address. From there it is your site to work.

Bulk delivery reaches Clackamas County addresses, including Lake Oswego, Oregon City, West Linn, Happy Valley and Wilsonville.

Materials for Mulino Projects

Decorative rock does the heavy lifting on most Mulino landscape work, and the choice comes down to whether you want stone that stays put or stone that reads as ground cover.

Beds, borders and dry creek beds

Willamette River Rock is rounded, water-worn stone for decorative beds and borders. It sits flat and reads as a finished surface rather than a pile of rubble.

Large River Rock handles dry creek beds, splash pads under downspouts and heavier bank work. Small stone washes out of those spots; large river rock does not.

3/8" Natural Pea Gravel is the smooth option for paths, dog runs and play areas. It is rounded, so it stays comfortable underfoot.

Driveways, pads and drainage

3/4 Minus is the standard Oregon base under driveways, parking pads, shop floors and shed bases. It carries 3/4 inch rock down to fines, so it compacts into a firm surface.

Drain Rock is washed and open, so water moves through instead of sitting. Use it for French drains, footing drains, drywells and downspout runs.

1/4 Minus beds pavers and flagstone and tops a compacted base. It also fine-grades paths where a coarser rock would be awkward underfoot.

Ground and Conditions in Mulino

Across the Willamette Valley and Portland Basin, the valley floor is deep slackwater silt left by the ice-age Missoula floods, with red clay and silty clay loam in the foothills. Silt and clay shed water slowly.

This part of Oregon takes 35 to 45 inches of rain a year, almost all of it between November and March, and the lowlands hold a seasonal high water table. Wet silt loses its strength fast under a load.

That is why an under-built base fails here: the material above it moves when the ground below it stays soft. 3/4 minus compacts into a firm layer, while clean stone stays open and lets water pass.

Winter rain also runs off bare silt and scours banks on the Willamette and its tributaries, and steep foothill slopes slide. Riprap armors culvert outlets, pond edges and cut slopes against that runoff.

Portland treats October 1 to April 30 as the wet weather season, when bare ground has to be stabilized within two days. Base and paving work concentrates in the dry months for that reason.

Winters here are mild and wet with only short freezes, so winter saturation and soft subgrade matter far more than frost heave. The county sets frost depth at 12 inches, the Oregon figure below about 2,500 feet.
