Professional Underpinning Services in NYC & Westchester County

Underpinning is the process of extending an existing foundation deeper below grade to allow safe excavation and prevent settlement or damage to nearby structures. At Confined Structures, we specialize in underpinning services across New York City and Westchester County, working alongside top geotechnical engineers to support complex urban projects.

 

Clients rely on our proven expertise in underpinning landmarked buildings and sensitive structures, especially in Manhattan, where space constraints and historical preservation add layers of complexity. Our work includes projects such as sub-cellar excavations, elevator shaft construction, and pool installations—all requiring precise and reliable underpinning methods.

 

We’ve successfully completed underpinning projects across NYC for:

• Excavation adjacent to existing buildings for new foundation development

• Pool construction within existing commercial or landmarked properties

• Elevator shaft excavation in occupied or historical structures

• Creating sub-cellars beneath existing or landmarked buildings
