Addition of water to bored piles

In water bearing ground, some water head (about 1 m) above the existing ground water table is sustained to stabilize the bore at the time of excavation below casings by pumping water to pile bore. This balanced head condition is created to minimize possible drawdown of surrounding water table that can affect the stability of nearby structures. Furthermore this helps to limit the possible inflow of water by piping from base of pile bore.
