Helical piles in Arkoma, Oklahoma

Expansive soil is the main foundation concern in Oklahoma. The Oklahoma Geological Survey notes that more than 75 percent of the state's bedrock units are possible sources of expansive soils, and that smectite clays can swell to 1.5 to 2 times their dry volume when wet. Shales in central and eastern parts of the state have moderate shrink-swell potential.

Wet springs followed by hot, dry summers drive repeated heave and settlement under slabs and footings. The state's code leaves frost depth to the local jurisdiction in Table R301.2(1), and Oklahoma City and Tulsa commonly use 18 inches according to a FootingDepth compilation. Helical anchors can also resist uplift on tornado shelters, carports and metal outbuildings when an engineer designs them.
