Get PriceJet Grouting Technique. With the jet grouting technique, a high-pressure jet of fluid is used to break up the soil in-situ and mix it with a self-hardening grout. The main advantage of this process is that large solidified soil/grout bodies can be produced in the ground with a relatively small drill string (drilling diameter approx. 15 cm).
Get PriceJet grouting can be used in a wide-range of soils to modify their characteristics by mixing with grout to form a soil-mixed column. It can be used to underpin buildings, for water cut-off, to aid excavation (tunnels, shafts etc.) and for mass soil-mixing and the encapsulation of pollutants.
Get PriceJet Grouting is commonly used in conjunction with Soil Mixing or Slurry Trenching to complete a continuous barrier or soil-mixed monolith in areas with difficult or limited surface access, subsurface obstructions, or sensitive utility locations.
