Compaction Grouting Services
Compaction grouting is a ground improvement technique that improves the strength and stiffness of the ground by controlled, high pressure injection of low-mobility cementicious grout. As the grout mass expands, the soil is displaced and compacted. If injected properly, the grout does not flow away from the injections zone or significantly permeate the surrounding soil. The result is a series of very stiff, bulbous grout columns surrounded by soil of increased density. Compaction grouting is used for sinkhole repair, improving soil under new or existing structures, settlement mitigation, the improvement of collapsing soils, liquifaction mitigation, and to construct foundations subjected to axial and/or lateral loads.
