Permeation and Rock Grouting

Permeation Grouting
This method describes the process of filling joints or fractures in rock or pore spaces in soil with a grout without disturbing the formation. More specifically, permeation grouting refers to the replacement of water or air in voids between soil particles with a grout fluid at low injection pressure so as to prevent fracturing. It is a technique that is generally used to reduce ground permeability and control ground water flow, but it also can be used to strengthen and stiffen the ground.

Rock Grouting
Rock grouting is the filling or partly filling by grout injection of fissures, fractures or joints in a rock mass with grouts without creating new (or opening existing) fractures, in order to reduce the permeability and increase the stiffness of the grouted mass.
