Foundation Support and Retrofit

Underpinning may be required to provide the additional foundation support needed to withstand increased loading, to halt ongoing settlement, to prevent structural settlement during adjacent excavation below footing level, and for seismic retrofit. Selection of the most appropriate underpinning method is a function of subsurface condition and project requirements and constraints.
