Deep Mixing Method - Portland Cement Association

The deep mixing method (DMM), also known as deep soil mixing or cement deep soil mixing (DSM/CDSM), is an in-situ soil treatment in which native soils or fills are blended with cementitious and/or other materials, typically referred to as binders. Ground treated by deep mixing methods has higher strength and lower compressibility than untreated ...

Deep Cement Mixing (DCM) Geotekindo

Deep Cement Mixing (DCM) is a soil improvement method where the in situ soil mixes with cement or other hardening agents such as (lime, slag, or other binders) at depths by augers. Deep mixing has been mostly used to improve soft cohesive soils, but sometimes it is used to reduce permeability and mitigate liquefaction of cohesionless soils.
