Underpinning

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.

Application

  • Temporary and Permanent Building Underpinning
  • Allows for basement construction adjacent to an existing building

Installation

  • Support building by underpinning existing footings with micropiles
  • Install a shoring system, typically soil nailing, to retain soil

Testimonials

Greg Shenkler, Skanska USA Building

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.
