Cement Pressure Grouting

Permeation grouting, also known as cement grouting or pressure grouting, fills cracks or voids in soil and rock and permeates coarse, granular soils with flowable particulate grouts to create a cemented mass.

Depending on the conditions, Portland cement or microfine cement grout is injected under pressure at strategic locations through single ‘port’ or multiple ‘port’ pipes. The grout particle size and void size must be matched properly to allow the cement grout to permeate. The grouted mass has an increased strength, stiffness, and reduced permeability.
