CUTTER SOIL MIXING
This deep mixing method for diaphragm cut-off soil improvement walls can be realized by using cutter wheels mounted on the end of the Kelly. In situ the soil will be mixed with binder slurry to install vertical soil- and water-resistance cut-off walls. This system can be used in almost any soil type.
