In situ support, or underpinning, is used to stabilise and strengthen a structure's existing foundations during construction or renovation works. There are various reasons why this might be necessary, such as the original foundation not being strong enough to support any additional building processes.
The use of the structure may also have changed, creating the need for extra support, while the soil around it might also have altered over time, affecting the foundations. During the underpinning process, the foundations will be extended to enable the additional support structures to be put in place – either in depth or by breadth.
