The dry deep mixing method is the most common method in scandinavia today. The drilling causes no vibrations and is assisted by cement slurry outflow from nozzles purposely located at the end of the soil. The properties of soft cohesive soils can be improved by mixing of a variety of chemical additives. Fhwa 2013 contains tables detailing deep mixing equipment tooling data and treated soil material properties.
Other additives can be used to fix pollutants in place to prevent leaching or to reduce soil permeability. The sole purpose of dcm is to improve shear strength of soil by in situ mix ing the soil with cement grout. Deep cement mixing dcm is a civil engineering deep foundation technique where a binder material typically cement is injected into the ground for ground stabilization and land reclamation in ground stabilization applications it is typically used to obtain a better load bearing capability of the existing soil e g. This mixing tool comprises a drilling rod transverse beams and a drill end with a head.
