Foundation settlement is the major problem faced by geotechnical engineers. If the settlement is severe, it may lead to the complete collapse of the structure even though the factor of safety against shear failure is high. There are many techniques or ways to reduce the foundation settlement, the floating foundation is one of the best solution.

The total vertical displacement that occurs at the foundation level is known as “Settlement”. Low bearing capacity of soil, poorly compacted soil, soil consolidation are the reasons for foundation settlement. Floating foundation causes zero settlement to the structure and provides the stable platform for the superstructure.
About Floating foundation:
A floating foundation is a type of foundation constructed by excavating the soil in such a way that the weight of structure built on the soil is nearly equal to the total weight of the soil excavated from the ground including the weight of water in the soil before the construction of the structure.
The main aim or purpose of the floating foundation is to balance the weight of removed soil by a structure of same weight which causes zero settlement to the structure. For this reason, it is also termed as balancing raft foundation.
Selection criteria for floating foundation:
Floating foundations are suitable for the following conditions,
