Bulk Rock and Soil for Portland, OR Projects

Bulk Rock and Soil for Portland, OR Projects

Portland is a large city in Multnomah County with 33 ZIP codes. Oregon Rock Supply lists bulk materials for decorative beds, borders, dry creek beds and paths, along with base rock, drainage aggregate, sand and fill for work around the property. Match the material to the job before ordering, then prepare a firm, accessible unloading area.

Portland materials for base, drainage and finish work

For a compacted driveway base, paver base or shed pad, use 3/4 Minus, also called 3/4 inch minus, dense grade or crushed base. Install it in lifts and compact each lift before adding the next.

Drain Rock is available as 3/4 clean or 1 1/2 clean. The open spaces between clean stone support water movement, while 1/4 Minus, also known as quarter minus or crushed fines, packs into a smooth walking surface for paths and patios. Natural Pea Gravel and #57 stone work well where a looser decorative or draining finish is wanted.

Portland ground prep, frost and drainage planning

Drainage deserves attention before gravel goes down. Oregon's Willamette Valley clay stays saturated from November through April, and a driveway without a draining base can rut during the winter. Check the grade around the project, move water toward an appropriate outlet and keep runoff from collecting at the base edge.

Use clean Drain Rock in a French drain trench or around a downspout outlet where water needs open voids to travel. Keep fines such as 3/4 Minus out of the drainage stone itself, since fines are intended to bind and compact. A separator fabric between native ground and aggregate helps keep soil from working into the rock.

Oregon's statewide frost-depth guide is 12 inches. Confirm frost and foundation requirements with the local building department before building a shed pad, footing or other structure. For a gravel drive, a compacted base depth of 4 to 6 inches suits light use, while heavier traffic, soft ground and repeated wet conditions call for a thicker engineered section.

Frequently Asked Questions

Common questions about gravel and aggregate delivery in Portland, OR

What should go in a Portland French drain or around a downspout outlet?

Use Drain Rock, either 3/4 clean or 1 1/2 clean, for the open aggregate around drain pipe and at downspout discharge areas. The clean stone leaves pathways for water instead of packing tightly. Set the pipe to a planned outlet and keep the trench grade moving in that direction.

How deep should a gravel driveway base be with Oregon's 12-inch frost guide?

The 12-inch figure is a statewide Oregon guide, not a site-specific Portland building requirement. A light-use driveway commonly starts with 4 to 6 inches of compacted 3/4 Minus, installed in separate lifts. Increase the base section where the subgrade is soft, traffic is heavier or winter water remains near the drive.

Which Portland base stone belongs under pavers or a shed?

Use 3/4 Minus under pavers and shed pads where a compacted base is needed. Grade the area first, place the material in lifts and compact each layer before setting pavers or building on the pad.

Which Portland ZIP codes should be included with an online order?

Enter the exact delivery ZIP and street address with the order. Portland ZIP codes include 97205, 97206, 97209 and 97210, as well as the other listed city ZIP codes. Accurate site details help plan access and the unloading location.
