Wet soil mixing improves weak soil properties by mechanically mixing in situ with a cementitious binder slurry.
- Improve bearing capacity
- Reduce settlement, lateral loads, and permeability
- Reduce liquefaction potential
- Increase slope stability
- Provide structural support
Wet soil mixing (also referred to as the deep mixing method) is used in almost any soil type. During the process, a drill string is advanced with mixing paddles. As the drill string advances and is withdrawn, binder slurry is pumped through it to the mixing tool. Mass soil mixing, also known as mass stabilization, uses a horizontal axis rotary mixing tool attached to the end of a track hoe arm. In this method, the binder slurry is injected through a feed pipe attached to the arm.
Wet soil mixing creates strengthened and stiffened individual soilcrete elements, rows of overlapping columns, or 100% mass stabilization. Treatment is possible up to 30 m depths. At times, predrilling is required before soil mixing because of obstructions or stiff soils. The ease of the process is contingent on soil type, strength, water content, plasticity, and texture.
