Different between friction and end bearing pile.

Question

Accepted Answer

Friction piles rely on skin friction for support while end bearing piles rely on the bearing capacity of the soil or rock at the bottom.

Friction piles transfer the load to the soil through frictional resistance between the pile surface and the soil.
End bearing piles transfer the load to the soil through the bearing capacity of the soil or rock at the bottom of the pile.
Friction piles are suitable for cohesive soils while end bearing piles are suitable for non-cohesive soils.
Friction piles are longer and thinner than end bearing piles.
Examples of friction piles include timber piles, steel piles, and composite piles while examples of end bearing piles include concrete piles and steel H-piles.
