The DJM dry jet mixing method is a deep mixing method that boosts the strength of soft ground by mixing into it improvement agent such as lime or cement in powder form. It has the same features as the CMC method that utilizes cement slurry. This method was adapted for commercial use from technology developed as part of a 1970s Ministry of Construction development project for new ground improvement methods. Standard mixing blades are 1,000mm but currently larger 1,300mm implementation is being studied.
