DEEP SOIL MIXING is a soil improvement technique used to construct cutoff or retaining walls and treat soils in-situ. This is accomplished with a series of overlapping stabilized soil columns (typically 36-inch diameter). The stabilized soil columns are formed by a series of mixing shafts (2 to 4) guided by a crane supported set of leads. As

Jet grouting creates in situ geometries of soilcrete (grouted soil), using a grouting monitor attached to the end of a drill stem. The jet grout monitor is advanced to the maximum treatment depth. Then high velocity jets (cement grout with optional water and air) are initiated from ports in the monitor. The jets erode and mix the in situ soil ...

Deep Soil Mixing (DSM) is a ground improvement technique through blending a hardening agent (usually cement grout) with the native soils, in situ. The process improves the strength and stiffness of the soil to increase bearing capacity, decrease settlement, and mitigate seismic issues. Also used to form walls for excavation support, erosion control, or contamination barriers.

Types of Stone Column Construction Vibro-Replacement (Wet Top Feed) (i.e. Vibroflotation) Stone column construction using water flush. Refers to the wet, top feed process in which jetting water is used to aid the penetration of the ground by the vibrator. Due to the jetting action, part of the in-situ soil is washed to the surface. This soil is then replaced by the backfill material.
