Deep Soil Mixing by the JAFEC Deep Mixing Method (DMM) is an advanced Ground Improvement method in which cement (or other agents) is mixed with in-situ soil to form-in-place soil-cement columns that increase the strength and reduce the compressibility of soft ground.

Deep Soil Mixing (DSM) improves soil by enhancing bearing capacity, controlling settlement, mitigating liquefaction, and aiding in soil remediation.

Soil mix columns can be used to stabilize slopes and levees, create in-situ gravity retaining structures, and can greatly reduce lateral loads on bulkhead walls.

Installation of stone columns to mitigate liquefaction-induced settlements. Deep soil mixing (DSM) is the mechanical process of breaking apart the in-situ soils while injecting and mixing a cement grout to create in-situ soil-cement.

Deep soil mixing columns prove instrumental in the construction of impervious earth-supporting structures and steady barriers against groundwater, while also enhancing the load-bearing attributes of the soil.

Deep Soil Mix (DSM) techniques The properties of DSM treated columns are influenced by the type and proportion of the cementing agent and soil properties, the mixing technique and mixing energy have strong influence on the strength and stiffness of the DSM columns.

Oct 3, 2022 · The deep soil mixing (DSM) technique uses augers to mix in situ soil at depths with a binder (cement, lime, slag, or other binders). Either a wet method or a dry method can be used for deep soil mixing.

Individual column diameters typically range from 0.6 to 1.5 m, and may extend to 40 m in depth. In some methods, the mixing action is enhanced by simultaneously injecting fluid grout at high pressure through nozzles in the mixing or cutting tools.

Theoretical Formulation: The present design of Deep Soil Mixing (DSM) columns in expansive soils is based on the heave prediction model originally proposed by Fredlund and Rahardjo (1993) and later revised by Rao et al. (1988). This model was evaluated as a part of the TxDOT Research Project 0-5179. The model

Mechanical deep mixing is the creation of vertical inclusions (columns or barrettes) by blending in-situ the soil with a stabilizing admixture to improve its mechanical characteristics (higher strength, lower compressibility).
