Underpinning

The proven Chance Helical Pier® foundation underpinning system provides these benefits:

  • Cost effective and technically superior to other remedial piering methods.
  • Predictable results; known capacity in specific soils.
  • Installs with limited access - no concrete trucks, heavy equipment, or grout pumps.
  • Limited excavation - site is minimally disturbed.
  • Used for new construction, enhances foundation strength on sites with poor soil conditions.
  • Seismic-resistant option may be added during rehab or in new buildings.




    • Where state or local laws require engineering consultation or planning for foundation work, consider the Chance Helical Pier underpinning system. Its low environmental impact makes a viable alternative recognized by governmental and building officials.

    Many other compression and tension challenges have been solved by Chance helical anchors:
    Tieback tendons, micropiles, and soil nailing are among the uses based on Chance anchor technology developed and applied over more than 80 years.
