Jet grouting is a construction process using a high kinetic energy jet of fluid to break up and loosen the ground, and mix it with a cement slurry. This hydrodynamic mix-in-place technique produces a soil cement material, commonly referred to as “jet-crete”. With respect to the extent and depth of the required Jet grouting…

Single fluid jet grouting – With this method the injected neat cement grout is used both to break up the soil matrix and to create the jet grouted column. Columns of up to 1000 mm in diameter can be obtained using this method. Double fluid jet grouting – Compared to the previous method a coaxial air-jet …

2 to 4 mm in diameter. The most important feature of jet grouting, when compared to injection or permeation grouting, is that jetting allows the cementing medium to be uniformly mixed with a wide range of soils, i.e. sands and gravel or even hard clayey soils. Other general advantages of jet grout­

Jet-grouting was introduced to British Columbia in 2004; since then, several ...

Jet-grouting is a trenchless method that utilizes grout to stabilize ground conditions within a project site. When employing this method, a small-diameter hole is drilled to the required depth, and as the drill string is lifted out of the ground, grout is injected into the borehole, forming a solid column in the ground.

As previously discussed, the diameter of a jet grouting column depends on the set of injection parameters and on the properties of the original soil. From the complete list of these variables, reported in Fig. 2, it is argued that a large number of combinations is possible. The experiments necessary to establish correlations should thus ...
