Pressure grouting involves injecting a grout material into generally isolated pore or void space of which neither the configuration or volume are known, and is often referred to simply as grouting. The grout may be a cementitious, resinous, or solution chemical mixture. The greatest use of pressure grouting is to improve geomaterials (soil and rock). The purpose of grouting can be either to strengthen or reduce water flow through a formation. It is also used to correct faults in concrete and masonry structures. Since first usage in the 19th century, grouting has been performed on the foundation of virtually every one of the world’s large dams, in order to reduce the amount of leakage through the rock, and sometimes to strengthen the foundation to support the weight of the overlying structure, be it of concrete, earth, or rock fill. Although very specialized, pressure grouting is an essential construction procedure that is practiced by specialist contractors and engineers around the world.

Grouting International Conference

Every ten years, those grouting experts have gathered in New Orleans, Louisiana, USA to exchange knowledge and share experience. ICOG, the International Conference Organization for Grouting was formed to organize and administer the every ten year meetings, the next of which is scheduled to occur February 15–18, 2012 in New Orleans. Each of the previous offerings has been filled with technical presentations, which have been permanently documented in technical publications.
