grouting

grouting Injection of liquid cement or chemicals into the ground where they set thus impeding or preventing water flow by reducing permeability and improving the strength of rocks by filling pores and fractures. Primary injection holes are spaced at regular intervals with infilling of secondary holes where necessary. The type of grout and its viscosity depends on rock type because of varying size of pores and fractures and hydraulic resistance. The migration of grout is controlled by permeability.
