How much does concrete cost in Missouri?

Ready-mix in Missouri 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 Missouri climate require?

Hot humid summers and cold salted winters mean both ACI 305 and ACI 306 provisions come into play within a single year, with air entrainment required for all exterior flatwork.

Under ACI 318, Missouri falls in exposure classes F3, C2, 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 Missouri?

Compiled reference tables put Missouri at about 33 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

Loess and claypan soils cover the north, karst limestone with sinkholes and caves runs through the Ozarks, and expansive clay is common around Kansas City.

Seismic

The Bootheel sits directly on the New Madrid Seismic Zone with the highest seismic design categories in the central United States, and the St. Louis area carries elevated demand.
