The Mixed-in-Place (MIP) method is particularly suitable in non-cohesive soils for the construction of cut-off walls as groundwater or pollution control, for remediating dykes and dams, or for the installation of structural retaining structures to secure terraces in the ground and excavation pits. In the MIP method, the surrounding soil is broken up with a single or triple auger, turned over and the pores filled with binder suspension. The individual units are combined to form walls by the step back method. In this, it is the size of the auger(s) that ultimately dictates the unit size. Reinforcing elements can be installed in the fresh MIP mix for structural strengthening.
