WHAT IS FOUNDATION REPAIR (UNDERPINNING)?

Underpinning is the process of modifying an existing foundation system by extending into subsurface stratum 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. Methods of underpinning include the construction of footings, stem walls and driven pilings for drilled piers (see definitions in sidebar at right). The underpinning, if properly designed and installed, provides the basis to lift the structure to a more acceptable elevation and provides vertical support to prevent the underpinned area from settling. There are many systems and many contractors that perform foundation repair work. The buyer must be educated and selective when deciding on the repair method for their home. Improper repair methods could cause tens of thousands of dollars in additional defects. For an experienced foundation repair contractor in your area, click here. Learn more about
