It is considered as the easiest, most inexpensive type and mostly recognized among construction industries. It is normally either a square or rectangular in plan. It is found that the compressive strength of the soil is usually much feebler as compared to that of the concrete, the contact area among the soil and the footing is greater as compared to that of the columns and walls.ĭefinition of Isolated Footing: An isolated footing is applied to support the load on a single column. In foundation design, soil study is vital to determine the most perfect type of foundation and the structural design is accomplished to find out footing dimensions and necessary amount of reinforcement. When there is feasibility for occurrence of differential settlement, the various types of footings should have been designed in such a manner to arrange each other separately. The settlement is dependent on the depth of the load, type of soil, and foundation level.
