The grout used in jet grouting is often a suspension of Portland cement in water. Jet grouting can be performed using one fluid (single fluid or single phase), two fluids (double fluid or two phase), or three fluids (triple fluid or three phase). The fluid in single fluid jet grouting is generally the Portland cement and water grout.
Jet Grouting -Procedure, Applications and Advantages for
Double Fluid Jet Grouting System. In double fluid system of jet grouting, the soil disaggregation and cementation are carried out by a single fluid i.e. the water-cement grout, but the difference is that the jet of grout is sent to an area of air that enhances the effectiveness of reducing the energy loss.

Jet grouting creates in situ geometries of soilcrete (grouted soil), using a grouting monitor attached to the end of a drill stem. The jet grout monitor is advanced to the maximum treatment depth. Then high velocity jets (cement grout with optional water and air) are initiated from ports in the monitor.

he jet grouting process has many unique aspects that enable it to perform in ways that other ground modification techniques cannot. Because jet grout is an erosional process which will create a relatively large column of soil-cement from a fairly small
Jet Grouting | Mainmark
Jet Grouting is the high pressure injection of a cementicious grout slurry into a soil strata to hydraulically mix the insitu material with grout. The resulting amended soil material is called " soil-crete ". The most common technique used in Jet Grouting involves the insertion of the Jet Grout Pipe to design depth for the bottom of the soil-crete column.

The cement slurry is delivered to the jet grouting machine by pipe from a mixing unit-hopper outside the building. Excess water and slurry coming back out of the ground is automatically drawn off in large diameter hoses from the drill stem holes and delivered to waste disposal skips.
– Triple-fluid system: water and air are used as breaking-up agents, while the cement grout is used as consolidation agent (TREVIJET T2) All Jet-Grouting techniques include a drilling phase followed by withdrawal and rotation at preset values, with simultaneous injection of fluids at high pressure.

Jet Grouting. Jet Grouting is a versatile erosion based system used to create in situ engineered geometries of soil-cement generally with limited required access. Jet Grouting creates in-situ columns of grouted soil using very high pressure grout injection.
Grouting Equipment for Heavy Civil and Underground
Jet grouting is accomplished by using a purpose-built system consisting of a drill rig, drill steel incorporating a jet grout monitor, high-volume mixing and batching equipment, high-performance pumps, large air compressors, and an automated jet grout control and data acquisition system.
