Underpinning vs Piling
Underpinning extends existing foundations to a deeper level; piling installs new load-bearing elements. Both can be used for subsidence repair or to support extensions. The structural engineer chooses from the cause and ground. This guide explains the difference.
The commercial value of resolving underpinning vs piling early is fewer delays, clearer budgeting, and reduced repeat disruption.
