RECENT SOIL MIXING APPLICATIONS IN THE

The application of the DMM primarily uses a wet injection method where a typical cement based grout is used as a drilling fluid and as a binder to form a solidified column(s) of soil-cement. Figure 1 shows three common DMM techniques: Deep Soil Mixing (DSM), Shallow Soil Mixing (SSM) and jet grouting.
