Applications of Jet Grouting Method

The applications of the jet grouting method can be grouped as follows:

  • Groundwater control

  • Displacement control

  • Support and retention

  • Environmental applications

Groundwater control applications include:

  • Preventing flow through excavation walls or bases

  • Controlling groundwater during tunnel excavation

  • Reducing leakage from water-retaining structures like dams or levees

  • Preventing or reducing contamination in soil water flow

Jet injection for displacement control includes:

  • Preventing movement of structures and soil during excavation or tunneling

  • Long-term support of tunnel walls during and after construction

  • Increasing safety factors of embankments or trenches

  • Supporting piles or walls to reduce lateral displacement

Jet injection as a retaining structure includes:

  • Foundation underpinning during excavation, nailing, or tunneling

  • Soil improvement to prevent failure due to insufficient bearing capacity

  • Transferring foundation loads through weak soils to stronger layers

Environmental applications of jet grouting include:

  • Encapsulating pollutants in soil to reduce contamination risk

  • Providing vertical and lateral barriers against polluted flows

  • Using reactive materials to form permeable reactive barriers for specific contaminations

This list shows the diverse uses of jet grouting, all of which require thorough knowledge, precise design, and careful execution and management.
