What is underpinning?  Foundation underpinning is the process of strengthening and stabilizing a settling foundation of an existing structure.  In order to achieve this with the underpinning method, galvanized steel shafts, also know as helical piers or helical piles, are inserted into the weak soil until they hit bedrock.  These piers allow the foundation load to be transferred to stable soil.   As a result, this deep foundation system helps to level the structure.  Chance Helical Pile Foundation Systems are an alternative to  micropiles as a common method in underpinning.

Here are some of the reasons you may want to consider underpinning:

  • The original foundation is simply not strong or stable enough.
  • The usage of the structure has changed.
  • The soil surrounding the foundation may have changed over time.
  • The construction of nearby structures may require the excavation of soil supporting the existing foundation.
  • It is more economical to fix the  present structure’s foundation than to build a new one.
