Rock Grouting

Rock grouting involves the injection of grout to penetrate and fill or partly fill cracks, joints, fissures and voids within the rock formation. The grout sets and reduces the pathways for water flow within the rock formation, decreasing its permeability (Lugeon). Rock grouting also stiffens weak rock formations by restricting movement of otherwise unrestrained fragments and the reduction of open voids and discontinuities. The flow and distribution of the grout depends on the fracture patterns within the rock and the discontinuity aperture and sharp of the grouted area or the purpose of the grouting. i.e. blanket, contact curtain or tunnel. Compile Ryobi offer a number of grouting solutions including traditional methods of grouting or modified G.I.N. methods for the construction of dam curtains etc.
