Drilled piers

 

Drilled piers, also known as caissons, are deep foundation systems used to support structures by transferring loads from unstable soil to stable, deeper soil layers.

 

Advantage

 

1)     High load capacity

2)     Depth flexibility

3)     Minimal vibration

4)     Adaptable to site condition

5)     Cost effective for large loads

6)     Less noise pollution

 

Disadvantage
