The process of pumping a slurry of cement or a mixture of cement and fine sand into crevices or voids in a rock or soil to densify the subsurface material. This process if often referred to as "compaction grouting".
The operation whereby grout is injected under pressure into openings in a dam or in its foundations.
A cement mortar mixture made of such consistency (by adding water) that it will flow into joints and cavities of masonry work to fill them solid.
(4) the injection of a cement slurry or other suitable materials (grout) under pressure into fissured, jointed or permeable rock in order to reduce the permeability or increase the strength. A process used to reduce water flow around bulkheads. The injection of grout into bedrock is usually done through diamond drill holes. Bentonite grout curtains have been used to reduce the permeability of waste rock.
Unstable rock and soil is strengthened by the injection of chemicals, cementitous grout, freezing or other methods.
Cement-like fluid which is poured or injected into the bore hole during well drilling to seal crevices and to prevent contamination or loss of drilling mud.
