Individual Footing or Isolated Footing. It is a continuous thick RCC slab that is resting on the soil that extends the entire footprint of the building and increases the bearing capacity of the soil.

Stepped spread footing Stoped Footing. It computes vertical and horizontal bearing capacity, settlement and rotation of a footing, and determines required longitudinal and shear reinforcement (punching). These undisturbed soils acting together with the widely spread, and locked in piles, provide a mechanical advantage. A higher concrete strength helps reduction the member’s size.
