Deep Soil Mixing When deep soil mixing is used, a drill rig with one or multiple counter rotating augers drills down into the ground to mix the soil with additives. Typically grout, lime, flyash, or even some other additives such as montmorillinite clay are added to the soil during the mixing process to improve strength and stiffness.

Deep soil mixing is an in situ ground improvement technique that enhances the characteristics of weak soils by mechanically mixing them with a cementitious binder. The action of mixing materials such as cement, fly ash, lime or bentonite with soil causes the properties of the soil to become more like soft rock.
