Permeation/Compaction Grouting

Permeation grouting is the placement of a grout material, cementitious or chemical, into voids in the soil or rock strata. This can be accomplished by either tremie or pressure grouting methods.
Compaction grouting is the placement of a low slump, low strength material under pressure into a loose soil strata to increase the stability of the soil.
Mine Stabilization Grouting

Mine stabilization grouting is the placement of grout or concrete materials into the mine workings to decrease the risk of damage due to subsidence of the overlying strata into the mine. Holes are drilled into the mine from the ground surface and either grout or concrete is placed into the mine depending on whether voids, broken material, or solid strata are encountered.
