    Grouting. Grouting is a process that involves injecting a fluid grout into soil, rock or man made material such as rock fill or masonry. The fluid grout cures and hardens, fills voids, increases strength and reduces the permeability of the ground. In addition to these effects, compaction grouting can be used to displace and compact the ground.
