Jet Grouting
The Jet Grouting process
The Jet Grouting process or Soilcrete is known as a soil-cement stabilisation. The soil around the bore is eroded with the aid of a high-pressure jet of water or cement suspension with a nozzle output speed 100 m/sec (possibly airborne). The eroded soil is rearranged and mixed in the cement suspension. The soil-cement mix is partly ejected into the annular space between the Jet Grouting rod and the bore. Different geometric configurations of Soilcrete elements are possible. The jet erosion distance varies according to the soil type and jet fluids used, and can reach diameters of up to 5 metres.
The Advantages of Jet Grouting
- Applicable to almost all soil types
- Individualised in situ treatment
- Designable strength and permeability
- Specific layer treatment
- Inert components only
- Vibration-free
- Applicable in limited working spaces
- Possibility of different Soilcrete elements
- Maintenance-free
- The safest and most direct sheetpiles method
- Able to operate around underground installations in service
- Faster than alternative methods
