Jet grouting is a technique used to improve the properties of foundation soil, or to reinforce (bonify) the soil. Through jet grouting, the existing soil structure is broken down, and soil particles are mixed in-situ with an injection mixture, forming a uniform mass with improved properties. This process increases mechanical parameters such as strength and deformability. The most used mixtures in jet grouting are water-cement and water-cement-bentonite. Jet grouting achieves pressures in the range of 300-700 bars, and the diameter of the injected body (jet grouted column) ranges from 60 cm to 250 cm.

We possess complete equipment for the execution of this technology: drills, cement silos, pumps, and injectors. Before starting work, we carefully examine the geological conditions at the site, project requirements, and other parameters to achieve the optimal and project-specific solution. By conducting a trial field and performing a parametric analysis, we verify the recipes and execution technology.
