Cement Deep Mixing

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.

The deep mixing method has the following advantages:
• Applicable for most soil types
• Installed at great depths
• Relatively fast installation
• Low noise and vibration level
• Formation of a DM wall for earth retaining and water barrier at the same location and time
• Less spoil soil, especially for the dry method
