Pressure grouting
Encyclopedia
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, resin
ous, 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 dam
s, 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.
Resin
Resin in the most specific use of the term is a hydrocarbon secretion of many plants, particularly coniferous trees. Resins are valued for their chemical properties and associated uses, such as the production of varnishes, adhesives, and food glazing agents; as an important source of raw materials...
ous, or solution
Solution
In chemistry, a solution is a homogeneous mixture composed of only one phase. In such a mixture, a solute is dissolved in another substance, known as a solvent. The solvent does the dissolving.- Types of solutions :...

Concrete
Concrete is a composite construction material, composed of cement and other cementitious materials such as fly ash and slag cement, aggregate , water and chemical admixtures.The word concrete comes from the Latin word...
and masonry
Masonry
Masonry is the building of structures from individual units laid in and bound together by mortar; the term masonry can also refer to the units themselves. The common materials of masonry construction are brick, stone, marble, granite, travertine, limestone; concrete block, glass block, stucco, and...

Dam
A dam is a barrier that impounds water or underground streams. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees are used to manage or prevent water flow into specific land regions. Hydropower and pumped-storage hydroelectricity are...

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.See also
