'''Soil nailing''' is a remedial [[construction]] measure to treat unstable natural soil slopes or unstable man-made (fill) slopes as a construction technique that allows the safe over-steepening of new or existing soil slopes. The technique involves the insertion of relatively slender reinforcing elements into the slope – often general purpose [[rebar|reinforcing bars]] (rebar) although proprietary solid or hollow-system bars are also available. Solid bars are usually installed into pre-drilled holes and then [[grout]]ed into place using a separate grout line, whereas hollow bars may be drilled and grouted simultaneously by the use of a [[Sacrificial part|sacrificial]] [[drill bit]] and by pumping grout down the hollow bar as drilling progresses. Kinetic methods of firing relatively short bars into soil slopes have also been developed.
