Soil injection is one of the essential methods used in soil treatment. It is applied to address soil settlement beneath slabs and villa yards, strengthen soil in coastal areas for foundation purposes, and fill voids that may appear under foundations. It is also used to inject soil before constructing buildings.

The process involves drilling several holes with calculated depths and diameters, followed by injecting a cementitious grout under specific pressure. In some cases, chemical additives are used to enhance the strength of the grout. The injection continues until each hole is fully filled, resulting in a compacted, void-free treated zone
