The Casagrande/TEC Cutter soil-mixer rigs feature soil-mixing cutter drums mounted on a dual-motor frame that is attached to a base by a Kelly bar. The rig can mix soil at depths ranging from 17 to 30 meters and fits Casagrande base carriers. The machine can be used to construct temporary diaphragm walls and cut-off walls. Depending on soil conditions, drilling rates can be as high as 35 sq m per hour. During use, cement slurry is mixed with excavated earth at the bottom of the tool, so the quantity of excavated earth is relatively small. It is controlled by a touch-screen control panel, which has information on soil conditions. Casagrande USA Inc.; 973-579-1906; www.casagrandegroup.com

The G13 is designed to cut cleanly through concrete, and, according to the manufacturer, the blade segments’ trapezoidal shape significantly reduces vibration. The cup wheels also are designed to reduce vibration and are able to grind concrete, cements, epoxy resins and other materials. Shoxx Technology; 312-327-5261; www.shoxxtechnology.com
