An isolated footing must be designed to avoid exceeding its bearing capacity and provide safety against overturning or sliding while preventing the ground from settling.

What is difference between isolated footing and combined footing?

This type of footing is preferred when only single column is appearing in the foundation plan of a particular project. Combined footing: Combined footing supports two or more column loads.
How do you calculate isolated footing?
Footing Calculation Example
- Volume = H/3 (A1+A2+(√A1 x A2)
- A1 = 2 x 1.5 = 3 Sqm.
- A2 = 0.5 x 0.3 = 0.15 Sqm.
- H = 0.15m.
- Now Volume = 0.15/3 x (3+0.15+(√3 x 0.15)
- Now Volume = 0.05 x (3.15+0.67)
- Volume = 0.19 m3
- Volume (V) = 0.19 m3
Where is isolated footing used?
