The average foundation wall, whether poured concrete or block, is 8 to 10 inches.

Increasing the thickness and strength of the walls is necessary if they must fight both leaks and soil pressure. The minimum depth of footings below the surface of undisturbed soil, compacted fill material or controlled low strength material (CLSM) shall be 12 inches (305 mm). Where applicable, the requirements of CBC Section 1809.5 shall also be satisfied. The minimum width of footings shall be 12 inches (305 mm).
