Jet grouting is a foundation process injecting cement grout under very high pressure into the soil through nozzles that create a jet effect. The jet effect is used to disrupt the soil and mix the injected grout with the soil in place. There are three Jet grouting methods that differ in the number of fluids injected simultaneously.
The monojet is an injection of cement grout, the twin-jet is an injection of cement grout and air and the tri-jet is an injection of grout cement, air and water.
