SOIL NAIL

Soil nailing is a remedial construction measure to treat unstable natural soil slopes or unstable man-made slopes as a construction technique that allows the safe over-steepening of new or existing soil slopes.

  • Stabilization of existing retaining wall
  • Excavating retaining structures in urban areas for high rise buildings and underground facilities
  • Landslide redemption
  • Stabilization of highway and roadway embankments and cut slopes
  • Tunnel portals in unstable and steep stratified slopes
  • Construction and retrofitting bridge abutments
  • Steep cutting stabilizations
  • Stabilizing of over steep existing embankments
  • Provide long term stability to existing concrete structures without demolition and rebuilding costs
  • Lastly, temporary excavation shoring

Soil nailing is a ground stabilisation technique used to reinforce and strengthen existing ground. It can be used on either natural or excavated slopes. It involves drilling holes for steel bars to be inserted into a slope face which are then grouted in place. It is economical and also applicable in seismic zones.
