Underpinning is the process of extending a building’s foundations deeper, in order to transfer its weight onto more supportive soil stratum. The process can help a building that is experiencing issues with subsidence, or simply one that needs to be stabilized for safety reasons. There are a few different underpinning methods, and the choice of which one to use will depend on what issues the building is facing.
The most traditional underpinning technique involves excavating the ground beneath a building in a series of controlled stages called pins, until it is exposed to a suitable soil stratum. This soil is then removed and replaced with concrete. The pier and base underpinning method is often used for buildings with existing shallow foundations and a need for greater depth.

Helical pilings are a more modern underpinning method that uses screw piles to extend the foundation deeper. These piles are screwed into the ground at various points until stable soil is reached, and then they are connected to the existing foundation. This method is ideal for buildings that are experiencing movement and need stabilization, as it can be completed in a relatively short amount of time.
