Jet Grouting (Trevijet Technology)

Jet Grouting is the process of dis-aggregating the soil and at the same time injecting and mixing it with cement admixtures using high-pressure jets. Although the diameters of drilling range from only 90 to 140 millimeters, columns of consolidated soil with diameters ranging from 600 to 2000 millimeters can be obtained by the Jet Grouting technology. Main applications are generally for underpinning, diaphragm wall gaps, tunnel consolidations, bottom plugs, slope consolidation, impervious cut-offs, and break-in or break-out for the TBM.
