Jet Grouting is a soil improvement technology that can be used for temporary excavation support, shafts, structure foundations, underpinning, piling, impervious bottom slabs, tunneling, and cut-off walls for environmental and/or hydraulic purposes. Jet Grouting’s enormous flexibility permits its use in a large variety of soils and in very heterogeneous conditions.
Jet Grouting is employed with specialized equipment that includes grout pumps, grout mixers, a drill rig, drill rods and injection monitors with horizontal radial nozzles. The process delivers high velocity fluids to erode, mix and stabilize in-situ soils using an engineered grout slurry.
Three main types of Jet Grouting are available: single, double or triple. Single Jet Grouting uses only the cementitious grout to disaggregate and stabilize the soil, the double uses grout mix and air and the triple uses water and air to disaggregate the soil and grout mix to stabilize it.
