Soil Nail Walls

Soil nails can be utilized for support of excavation needs or slope stabilization and present a versatile and cost-effective solution.  Soil nails can be designed for temporary or permanent applications and finished with either a shotcrete facing or Tecco mesh. The length and diameter of the soil nails can be designed to meet the specific needs of your project. Projects utilizing soil nail walls are typically excavated using a top-down excavation approach and are installed in stages or rows called lifts.

The Benefits of Soil Nail Walls:

  • Permanent or Temporary applications
  • Tailored to the geology of the site.
  • Limited Access Applications
  • Excavation can be performed simultaneously with the installation.
  • Can be a quicker and more cost-effective solution for excavation support.

How it Works:

  • The excavation contractor makes an initial “cut”, typically 5’ in height.
  • A row of soil nails, typically grouted hollow bars or helical anchors, are installed on engineered centers (typically 5-6’ spacings).
  • Steel reinforcing is placed around the nail (for shotcrete applications) and the nails are terminated with plates.
  • A shotcrete or tecco mesh facing is utilized to tie the individual nails into a system.
  • The excavation contractor will then make the next cut and the process repeats until the full height of the excavation is completed.
