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.
