Expert Underpinning & Foundation Repair in Nashville 

What is underpinning?

United Structural Systems, Inc. specializes in Underpinning Commercial and Multi-Story Buildings in Nashville and Middle TN.

In some ways, commercial foundation repair is similar to residential foundation repair because many of the same techniques, such as underpinning, can be used.

Underpinning is the process of extending the load bearing portions of the foundation to a deeper elevation, usually bedrock. This is accomplished by excavating to expose the foundation, attach the pier bracket to the foundation and using the reciprocal load of the structure. Piles are hydraulically driven to end bear on bedrock. After all piles have been installed, the structure can be lifted back to its original elevation or stabilized in place.

Underpinning can be used as a foundation repair method in a variety of situations, such as:

  • To lift and stabilize a settled structure.
  • Increase the capacity of an existing foundation or remove the surcharge load of a structure from nearby excavations.
  • USS can design and install an underpinning system tailored to your specific situation.

If you have commercial, municipal, or any other type of structure, call or contact United Structural Systems to schedule an appointment with a qualified foundation repair expert to assess your needs.
