Jet grouting is a method of soil stabilization which involves the injection of a stabilizing fluid into the subsoil (or the soil under treatment) under high pressure under high velocity.
Applications
- For construction of horizontal barriers
- Control of groundwater
- Underpinning
- Tunneling
- Support for excavation
Advantages
- Large cemented material column creation without causing huge ground disturbances (subsoil)
- Columns form continuous elements forming in different shapes thus improving the mechanical properties and decreasing porosity
- Improvement in construction process thus emerging out with a better design philosophy
- It’s attractive nature in terms of confined space working and under difficult site conditions
Disadvantages
- Continuous flushing is required to avoid clogging
- Requires specialized and experienced applicators
- Initial higher costing
