SOIL NAILING

Soil nailing is a stabilization method of reinforcing existing soil by installing threaded steel bars into slopes or cuts as excavation proceeds from top down. Steel bars are installed in drilled holes and then grouted to tieback the face of the wall. A constructed face is installed over the steel bars, typically made of shotcrete as a face cover, which is reinforced using woven wire mesh over steel plates.

Soil Nailing Advantages:

• Can be used to follow soil curves.
• Equipment is portable, fits in tight spaces.
• The technique is flexible, easily modified.
• Creates less noise and traffic obstructions.
• Less impact on nearby properties.
• Can be used as a form for permanent walls (eliminating backfill)
• Requires minimum space.
