When We Use Pile Foundation

Pile foundations are generally adopted in the following situations

  1. Pile foundations can be used in the construction of piers, docks or other marine structures as fender piles.
  2. Heavy and uniform load is coming to the soil from the structure.
  3. When the structure is situated on or near sea-shore or river bed and foundations are liable to be scoured due to the action of water.
  4. When timbering of the excavation trenches is not possible.
  5. Where raft or grillage foundations are either very costly or cannot be adopted due to local difficulties.
  6. When the underneath soil is waterlogged and compressive. Hard firm strata is situated at a deeper depth.
  7. When it is impossible to maintain the foundation trenches in dry condition by pumping due to heavy inflow of seepage or capillary water.
  8. The sub-soil water table is very high which can easily affect other foundations.
  9. Pile foundation can also be used as anchors.
