Soil Nails

Soil nailing (knitting of the soil) is a stabilization method of reinforcing existing soil by drilling. Installing and grouting threaded steel bars into slopes or cuts as construction proceeds from top down.

By applying the latest technology and our own extensive experience, SDIs soil nailing methods successfully create retaining walls that reinforce the soil mass without excavating the soil behind the wall. The walls are constructed in-situ and built in stages from the top down, one lift at a time, shoring the exterior and surrounding walls.

Various temporary and / or permanent facing elements are available including shotcrete, precast concrete, and cast-in-place concrete. Performing the construction top-down can save SDI clients considerable time and money over conventional construction methods.

SDI recognizes the value and promotes the implementation of design/build solutions. Our advanced soil nailing technology can be applied to

  • New permanent construction
  • Temporary construction
  • Restoration of existing structures
Our field personnel are adept at working in confined areas using specialized equipment.

At SDI, our goals include an emphasis on maintaining a safe job site while delivering on-the-job performance that is essential for meeting demanding schedules.
