Soil nailing is a technique in which soil slopes, excavations or retaining walls are reinforced by the insertion of relatively slender elements - normally steel reinforcing bars. The bars are usually installed into a pre-drilled hole and then grouted into place or drilled and grouted simultaneously.

They are usually installed untensioned at a slight downward inclination. A rigid or flexible facing often pneumatically applied concrete otherwise known as shotcrete or isolated soil nail heads may be used at the surface.
