Under-Reamed Piles are widely used for different types of soils such as sandy soils, clayey soils and also expansive soils. Under-Reamed Piles are required to be taken down to a certain depth because of the following considerations:
- To avoid the undesirable effect of seasonal moisture changes in expansive soils such as black cotton soils.
- To reach hard strata.
- To take the foundations below the scour level.
- To obtain adequate capacity for downward, upward, lateral loads and moments.
- To take the foundations below the scour level
- Under-Reamed Piles are also used under situations, where the vibration and noise caused during construction of piles, are to be avoided.
- They have also been found useful for factory buildings and machine foundations
