Jet grouting is a fairly common technique, but one in which Soletanche Bachy has unique expertise.<\/p>\n<\/div>
The jet grouting process involves cutting the soil with a high velocity jet of fluid(s) and mixing this eroded soil with a self-hardening grout<\/strong> to form columns and other structures in the ground.<\/p>\n The power delivered by the jet breaks up the native soil by erosion along a given radius depending on the type of soil and its compactness. Part of this soil is replaced by the cement grout brought by the jet<\/strong>. This replacement of a certain amount of native soil depends on the technique used and the final objective. The excess volume of mixture exits freely towards the surface during the process.<\/p>\n In the vast majority of applications, the equipment is rotated and raised so that the soil-cement component formed in situ is roughly cylindrical (a column).<\/p>\n<\/div>
