Underpinning is a method used to increase the foundation depth and transform simple basement into a welcoming, finished basement, with 8-foot ceiling height, which adds square footage and value.
It is the process of modifying an existing foundation system by extending it to or into subsurface strata that is deeper and more stable than the near surface soil that supports the existing foundation system. This is done to provide vertical support that is not present in the existing design.
House prices in Toronto and the surrounding areas keep rising. As prices rise then useable space becomes a premium. Underpinning is a great way of making that unusable basement into something that can become part of your home. Underpinning means reinforcing an existing foundation or digging out the foundation to add ceiling height.
