These technologies use crane and excavator mounted mixing tools to mix various binders with the native soils to create stabilized soil in situ. These two mass mixing methods differ from deep mixing by providing more economical soil treatment for depths less than about 40 ft. (12 m), and the design strength of the mixture is usually lower than that for deep mixing.</p><p>
