How much does concrete cost in Oregon?

Ready-mix in Oregon runs roughly $155 to $195 per cubic yard. That is an estimated band, not a quote — published US price sources disagree with each other by nearly two to one. How we source price figures.

What does the Oregon climate require?

The wet mild Willamette Valley sees limited freezing and rain is the main placement obstacle, while Central and Eastern Oregon are high desert with severe freeze-thaw cycling.

Under ACI 318, Oregon falls in exposure classes F1, C2, S1. Air entrainment is required for exterior flatwork. Air entrainment is required for classes F1, F2 and F3.

How deep is the frost line in Oregon?

Compiled reference tables put Oregon at about 18 inches. That figure is orientation only. The footing depth you actually have to build to is determined by your local building department — IRC R403.1.4 requires footings to extend below the locally determined frost line, and there is no national number.

Soil concerns

Willamette silt and expansive clay west of the Cascades, volcanic ash and pumice soils around Bend, and alkaline sulfate-bearing soils in the eastern basins.

Seismic

The Cascadia Subduction Zone drives high seismic demand along the coast and through Portland and the valley, with the Portland Hills fault adding shallow local risk.
