Cutter Soil Mixing (CSM), a deep soil mixing method, was used to rehabilitate the Herbert Hoover Dike, Florida by installing a cutoff wall. After an introduction to the method including remarks on its advantages and limitations, the rehabilitation project and its background are presented. The paper describes the necessary approach to apply Cutter Soil Mixing under the specific site conditions. Finally, results obtained from an extensive testing program are discussed.
