Cement Deep Mixing Association - BBRI

Cement Deep Mixing (CDM) is a method for improving the ground to a prescribed strength by mixing cement slurry with the soft soil in situ. Generally, the cement used is either ordinary portland cement or a mixture of portland cement and blast-furnace slag.

Introduction - cdm-gr.com

The CDM method is an applied chemical solidification technique, which inserts and mixes a cement slurry into soft ground to produce a more solid ground foundation. Established in 1977, the Cement Deep Mixing Method Association consists of companies that joined together to promote and improve this method.
