Various types of footings are given below.
Simple or plain footing:
In this type of footings, three concrete cross-sections are stacked upon each other and forms as a step. This is also called as a step foundation. This is mostly used in residential buildings

It is a footing in which 45° slope is maintained from all sides. Due to the provision of slope, the cost of footing reduces as concrete and reinforcement required will be less compared to the trapezoidal footing.
4) Strap footing:

This type of footing is necessary when a column is very close to the boundary of the property and hence there is no scope to project footing much beyond the column face. The footing is to be designed for transferring loads from both columns safely to the soil. The two columns are connected by a cantilever strap beam.
