Jet grouting

Depending on the equipment used, the energy applied and the type of ground, columns can be implemented with diameters between 0.5 and 3.0 meters. The largest diameters are obtained by simultaneously or sequentially injecting several types of fluid (double jet = slurry + air, triple jet = slurry + air + water). [...]

Jet grouting is poorly suited, as a rule, to soils with blocks and rough gravel, to organic materials and to soils through which large volumes of water flow.
