cohesion piles or friction piles in pile foundation
- This type of friction piles transmits most of their load to the soil through skin friction. This process of driving such piles close to each other in groups greatly reduces the porosity and comprehensibility of the soil within and around the groups.
- This type of piles category is some times called compaction piles. Because of the process of driving the pile into the ground, the soil becomes molded and, as a result, loses some of its strength(friction).
- This type of pile is not able to transfer the exact amount of load which it is intended to immediately after it has been driven. Normally, the soil regains some of its strength 3- 5 months after it has been driven.
