Mass Soil Mixing Deep Soil Mixing Ground Developments

Mass soil mixing is a fast and cost–effective, deep soil mixing method for the in–situ improvement of soft soils including clay, peat, and silt by disaggregation of the soil using an excavator mounted rotavating tool. The technique can also be utilised when dealing with saturated soils such as running sands. In general, the principle is the same as deep columns however mixing usually takes ...
