The main principle of this technique is a high kinetic energy cement grout jet to break up the terrain, and then adding cement to provide it with compression and shear strength comparable to a concrete floor.Phase 1 : execution phases Drilling: drilling and removing the core of the terrain to insert a winged column to the depth of treatment required. The lower end of the column has a drilling tool, a bypass valve and one or more orthogonal injection nozzles on the axis of the column. Phase 2
rogrammed extraction and injection: the mixture is injected at high pressure while the winged column is removed. We leave the jet in place, and the terrain is treated in accordance with the desired shape and dimensions by a combination of extraction speed and rotation of the column.
