Permeation Grouting

Permeation grouting is the filling by grout injection of accessible pores between the solid particles in a permeable soil by grout without disturbing the structure of the soil. It is a technique that is generally used to reduce ground permeability and control groundwater flow but also can be used to strengthen and stiffen the soil mass.

  • Systems of applications
  • Tube a Manchette (TAM) Grouting
  • End of Casing Grouting
