The grouting technique is used
to improve soils and certain
man-made structures (masonry,
concrete, etc.)

• Filling of natural cavities (karsts,
  dissolution voids, etc.)
  
  
• Filling of man-made cavities (especially
  underground quarries)
  
  
• Re-compacting of accidentally
  decompressed soils (water leakage,
  nearby excavations)
  
  
• Filling of soil fissures to prevent water
  flow (cut-off curtain wall under a dam,
  containment cut-off wall around
  excavations or a shaft, etc.)
  
  
• Permeation of sands and gravels
  using a liquid product which sets after
  injection
