How much does concrete cost in North Carolina?

Ready-mix in North Carolina runs roughly $125 to $165 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 North Carolina climate require?

A mild coastal plain, genuine freeze-thaw through the Piedmont, and hard mountain winters in the west where salt use pushes exterior flatwork toward F3-grade mixes.

Under ACI 318, North Carolina falls in exposure classes F1, C1, S0. Air entrainment is required for exterior flatwork. Air entrainment is required for classes F1, F2 and F3.

How deep is the frost line in North Carolina?

Compiled reference tables put North Carolina at about 10 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

Piedmont saprolite and red clay weather deeply and hold water against foundations, while the coastal plain is sandy with a high water table and scattered organic pockets.

Seismic

Low to moderate — western North Carolina sits near the Eastern Tennessee seismic zone, the most active in the Southeast, while the coast designs for hurricane wind instead.
