End bearing piles :-
- This type of piles derive most of their load carrying capacity from the resistance of the stratum at the toe of piles , which is known as end bearing piles.
- The piles are driven in to the ground until a hard stratum is reached and the piles acts as pilars supporting the superstructure and transmitting the bed below.
Friction piles :-
- The piles obtain the greater part of their load carrying capacity by skin friction , which is known as friction piles.
- The piles do not reach to an impermeable stratum but are driven to some depth into weak or soft soil , their load carrying capacity is derived partly from end bearing and partly from the skin friction developed between the surface of the pile and surrounding soil.
