Permeation Grouting
Permeation grouting is a technique that involves injecting grout into the ground to fill voids and cracks in soils or rock. The grout flows into the voids under low pressure without disturbing the surrounding soil or existing structures. Grouts used in permeation grouting can include cement-based grouts, other particulate materials, or chemical grouts. The choice of grout depends on the soil type and specific project requirements.
Permeation grouting is most effective in granular soils such as sands and gravels with low fines content
and is commonly employed for stabilizing soils below foundations or reducing permeability for groundwater control. It can be tailored to specific soil conditions using different grouts and results in a less permeable, stronger, and more uniform soil mass.
