List of featured suppliers of UNDERPINNING on Building Products Index
Underpinning is the act of strengthening or stabilizing the foundation of a structure. This is typically done by reinforcing the existing foundation with additional material or by excavating and pouring a new, deeper foundation below the existing one. Underpinning is often necessary in situations where the soil beneath a building has become unstable, causing the foundation to settle or shift, or in cases where a building is being expanded or renovated and needs to support additional weight.
