Jet-Grout is a ground improvement technology which, by mixing in-situ soil with Cement Grout, strengthens the Soil’s mechanical properties, solidifies lose soil and stabilizes the Ground , in a process where high speed jets of cement grout from nozzles provided on rotating drilling rods, or on rotating deep mixing tools, are impregnating the soil within a certain pre-determined radius, forming a shaft of Soil-Cement material of predetermined strength, shape and cross sectional area. A figure is here provided to visualize the process.Jet-Grout is a ground improvement technology which, by mixing in-situ soil with Cement Grout, strengthens the Soil’s mechanical properties, solidifies lose soil and stabilizes the Ground , in a process where high speed jets of cement grout from nozzles provided on rotating drilling rods, or on rotating deep mixing tools, are impregnating the soil within a certain pre-determined radius, forming a shaft of Soil-Cement material of predetermined strength, shape and cross sectional area. A figure is here provided to visualize the process.The “FS Soil-cement Column” system is particularly suited for the very poor and water saturated soil formations found in the coastal areas of the Philippines, where the soil in general is characterized by very low bearing capacity and low shear values. The overlaying soil strata of this formation have an extremely high liquefaction potential in earthquake condition.
The “FS Soil-Cement Column” method produces high mechanical characteristics shear and compressive strength for the soil treated, maintaining the costs affordable and competitive. FS uses different tools and procedures for different soil types to achieve maximum soil strength.
