pile foundation is the type of deep foundation, ie the depth
of foundation is greater than the width.

a type of foundation which is used for the highrise 
buildings, and in the soft soil.

Pile foundations are the part of a structure used to carry 
and transfer the load of the structure to the bearing 
ground located at some depth below ground surface. The main 
components of the foundation are the pile cap and the 
piles. Piles are long and slender members which transfer 
the load to deeper soil or rock of high bearing capacity 
avoiding shallow soil of low bearing capacity The main 
types of materials used for piles are Wood, steel and 
concrete. Piles made from these materials are driven, 
drilled or jacked into the ground and connected to pile 
caps. Depending upon type of soil, pile material and load 
transmitting characteristic piles are classified 
accordingly. In the following chapter we learn about, 
classifications, functions and pros and cons of piles.

Pile foundation is a deep foundation & it is uses to 
transfer the heavy load. the ratio of the l/b is very high.
It is uses when the bearing capacity of soil is very less.

there are two types foundation 1.shallow 2.deep  .pile 
foundation is types of deep  foundation .it use in those 
place where the bearing capacity of soil is very 
low.minimum lenth of pile foundation is 6m.

the foundation which is standing on piles...means the piles like structure is constructed below the foundation to sustain the heavy load

this type of foundation is used in the soil having low 
bearing capacity......that is the good soil @higher deth 
10m to 15m..........

Pile Foundation is a type of Deep foundation, and is mainly 
used to Transfer heavy loads to the hard stratum of soil 
which is located at deeper depths, where the shallow depth 
soil having low bearing capacity and also expansive in 
nature.
