What Is Grouting Types of Grouting Advantage of Grouting

WebbCompaction grouting injects stiffer grout into the ground at a specified depth using medium to high pressure. The grout injection process creates and expands a grout cavity (e.g. a grout bulb) near the bottom of the column which presses against the surrounding soil increasing its density. WebbCompaction grouting is a ground treatment technique that involves injection of a thick-consistency soil cement grout under pressure into the soil mass, consolidating, and thereby densifying surrounding soils in place. The injected grout mass occupies void space created by pressure-densification.
