Concrete Leveling in Saint Louis, MO

Concrete Leveling in Saint Louis: local conditions

Saint Louis, MO sits on highly expansive clay and has a humid continental climate near 40" of rain a year with heavy spring storms. The local water table is variable — expansive clay swells when wet and shrinks when dry, with moderate winter freeze–thaw cycling, and basements are common, especially in older stock. In practical terms, expansive clay is one of the Midwest's leading causes of foundation movement — which is exactly why concrete leveling is a common need here.
