Soil Nail Walls are constructed from the top down.  The construction sequence for the typical Soil Nail Wall includes:

  • Initial excavation of up to 5 feet deep depending upon design parameters and soil conditions.

  • Installation of the first row of helical soil nails to the required angle of inclination, torque and embedment lengths.

  • Placement of drainage system (if required).

  • Placement of wall reinforcement and bearing plates.

  • Placement of shotcrete to the required wall thickness.

  • Allow for cure time and then repeat the sequence for successive rows of soil nails.

  • Continue the process until the final design depth (wall height) is achieved.
