How much does concrete cost in South Carolina?

Ready-mix in South 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 South Carolina climate require?

Hot humid summers govern the calendar, with ACI 305 hot-weather placement from May into September. Freezing is brief and shallow outside the Upstate.

Under ACI 318, South Carolina falls in exposure classes F0, C2, S0. Air entrainment is not required in most of the state. Air entrainment is required for classes F1, F2 and F3.

How deep is the frost line in South Carolina?

Compiled reference tables put South Carolina at about 4 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

Coastal plain sand and soft marsh clay surround Charleston, where deep foundations are common, while the Upstate sits on Piedmont red clay over saprolite.

Seismic

Charleston carries the highest seismic demand on the East Coast following the 1886 M7 earthquake, and the coastal plain's loose saturated sands are liquefaction-prone.
