Foundation Underpinning

Underpinning is the process of improving or strengthening an existing foundation.

According to PCA the need for underpinning of a foundation has various causes -:

  • Failure of the original foundation.
  • Change in use of a structure, such as adding levels
  • Environmental changes such as flood or drought can cause a structure to move.
  • Siesmec events such as earthquake can necessitate underpinning.
  • To protect existing structures immediately adjacent to new construction and excavation.
