The deep-mixing soil stabilization method creates improved soil-cement columns. The quality of the improved ground must be evaluated constantly. The conventional methods are applied a considerably long time after the completion and depend on the results of tests, necessary for reworks. The applicability of resistivity methods have been developed and studied for evaluating the quality variations of improved ground immediately after the construction. This resistivity method is based on the axial resistivity changes of a cone sensor inserted in the hardening body. As a result, it was proven to be effective in the evaluation of soil-cement columns.
