How much does concrete cost in Maine?

Ready-mix in Maine runs roughly $150 to $190 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 Maine climate require?

One of the deepest frost lines in the lower 48 and a freezing season that runs October into April; winter placements need heated enclosures and full ACI 306 protection.

Under ACI 318, Maine 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 Maine?

Compiled reference tables put Maine at about 74 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

Glacial till and shallow ledge cover most of the state, while the coastal lowlands hold soft, sensitive Presumpscot marine clay that has low bearing capacity.

Seismic

Low to moderate — New England has persistent low-level activity but ordinary residential flatwork needs no special seismic detailing.
