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.
