Cementitious grouting is a process in which a fluid cementitious grout is pumped under pressure to fill forms, voids, and cracks. It can be used in several settings including bridges, marine applications, dams, and rock anchors. The grouted mass has an increased strength, stiffness, and reduced permeability.
Generally, grout is a mixture of cement, sand, and water or chemicals used to fill gaps. They are commonly used in the repair of concrete cracks, fill seams and gaps in tiles, seal and fill gaps for waterproofing, as well as for soil stabilization.
Portland cement
Generally, grouts that consist of a flowable mixture of solids and water are termed suspended solids grouts. The most common suspended grout is Portland cement, often with a variety of additives.
Where is grouting done?
Typically, grouting is carried out by driving pipes or boring holes into the ground, and then pumping the grout solution at high pressure through inserted tubes. The extent of grouting required for a particular area is determined by investigation of ground conditions and calculation of a drilling pattern.31-Aug-2020
