  • Deep cement mixing - Wikipedia

    Deep cement mixing (DCM) is a civil engineering deep foundation technique where a binder material, typically cement, is injected into the ground for ground stabilization and land reclamation.In ground stabilization applications it is typically used to obtain a better load bearing capability of the existing soil, e.g. in order to bear buildings and other structures.
