How much does concrete cost in South Dakota?

Ready-mix in South Dakota runs roughly $140 to $180 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 Dakota climate require?

Long severe winters with deep frost and hot dry summers; ACI 306 cold-weather concreting governs a large share of the construction year and wind accelerates surface drying in summer.

Under ACI 318, South Dakota falls in exposure classes F3, C2, S2. Air entrainment is required for exterior flatwork. Air entrainment is required for classes F1, F2 and F3.

How deep is the frost line in South Dakota?

Compiled reference tables put South Dakota at about 64 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

Pierre Shale across the central and western counties is highly expansive and sulfate-bearing, so sulfate-resisting cement is common, while glacial till covers the east.

Seismic

Very low seismicity statewide. No special seismic detailing is required for flatwork.
