how many types of foundation are there based on depth

Solution (By Examveda Team)

Foundations based on depth are classified into two types:
1. Shallow Foundation:
These foundations are placed near the surface of the ground or at a shallow depth relative to their width.
They are suitable for soils with good bearing capacity near the surface.
Examples include spread footing, strip footing, and mat foundation.
2. Deep Foundation:
These foundations extend deep into the ground, well below the surface, to transfer loads to stronger soil or rock layers.
They are used when surface soils are weak or compressible.
Examples include pile foundation and caisson foundation.
Thus, the two main types based on depth are shallow and deep foundations.
