The Mixed-in-Place method is particularly ideal in non-cohesive soils for producing cut-off walls as a soil improvement, groundwater barrier, or to encapsulate inherited pollution, for repairs to dikes and dams, or as structurally effective retaining walls for topo-graphical changes, excavation pits, as well as soil mechanical measure against liquefaction. In the Mixed-in-Place method, the existing soil is broken and mixed horizontally and vertically with a double auger, transferred and the pore spaces are filled with a binding agent slurry. The individual insertions can be used as individual elements or combined to walls using the pilgering step process. The auger dimensions ultimately determine the insertion size. Reinforcement can be inserted into the fresh Mixed-in-Place panel for structural strengthening.
