Methods to control or arrest subsidence include reduction of pumping draft, artificial recharge of aquifers from the land surface, and repressuring of aquifers through wells, or any combination of these methods.
Can subsidence be fixed without underpinning?
Underpinning is not always necessary to rectify a subsidence issue, and is increasingly being used only as a last resort. There are two particular situations where underpinning should not be carried out. The first of these is if the ground movement that caused any damage has stopped and is unlikely to reoccur.
