Underpinning is a highy specialized construction. Underpinning
is the total or partial resupport of an existing structure by
a new foundation system. The method may consist of concrete piers,
drilled or jacked pile foundations, or even ground freezing. Installation
is done always in stages so that the damage risk associated with
transferring the load from the existing to the new foundations
can be minimized.
Underpinning requires a careful evaluation of existing building
loads and proposed underpinning method, monitoring of the existing
structure for signs of distress, and expert quality control.
