Underpinning

micropile underpinning and soil nail shoring

Using micropile underpinning in conjunction with soil nail shoring, we can support existing structures adjacent to deep excavations while maintaining the integrity of the buildings.

  • Temporary and Permanent Building Underpinning
  • Allows for basement construction adjacent to an existing building
  • Support building by underpinning existing footings with micropiles
  • Install a shoring system, typically soil nailing, to retain soil

Subsurface did a great job upfront making sure that we were installing the most effective solutions for our project. And despite a challenging schedule and unexpected underground conditions, the job was still completed ahead of schedule.
