Cutter Soil Mixing CSM Cutter Soil Mixing (CSM) was developed from diaphragm wall technology and utilizes two sets of counter rotating, vertically mounted cutter wheels. The wheels cut the surrounding soil while at the same time blending the injected cement slurry with the in situ soil to form soil cement panels, 1.7 to 5 feet in width.
Deep Soil Mixing Ltd (DSM) provides two types of deep soil mixing for geotechnical and environmental applications, including mass mixing, and column mixing. Both systems offer wet and dry soil mixing solutions which enable the additives to be placed as wet slurry or dry powder.
ing deep cement-soil mixing (DCM) is one of the most suitable methods to overcome this problem. The sole purpose of DCM is to improve shear strength of soil by in-situ mix-ing the soil with cement grout. Ap-plication of ground improvement method using DCM method allows excavation works, construction of embankments for highways, reser-

These methods improve the soil and its engineering properties to increase its in-situ strength, to control settlements and to improve its performance under cyclic or other transient loads. The techniques include wick drains, stone columns, sand columns, deep soil mixing, grouting, lime columns, vibrowing, jet grouting and cutter soil mixing.
The inclusion of soil–cement columns using the deep soil mixing method is one of the stabilizing techniques that have been applied successfully worldwide. The advantage of deep soil mixing method is that it not only improves the strength of ground, but is a superior method for the limitation of settlement.
Deep Soil Mixing, or wet soil mixing, is a soil treatment/ground improvement technique where in-place soils are mixed or blended with cement or other reagent materials. The result is columns of soil-cement with significantly increased strength and reduced compressibility.

As of January 1, 2020, North America Keller companies Bencor, Case Atlantic, Case Foundation, Hayward Baker, HJ Foundation, Keller Canada, McKinney Drilling and Moretrench have joined together and rebranded to Keller.
The deep mixing method (DMM) is an in situ soil treatment in which native soils or fills are blended with cementitious and/or other materials, typically referred to as binders. Compared to native soils or fills, the soil-binder composite material that is created has enhanced engineering properties such as increased strength, lower permeability ...
Our current fleet consists of four units equipped for the dry, as well as the MDM™ deep mixing methods. Each unit is made up of an installer and a carrier that handles the dry binder. All units exerts very low ground pressure facilitating installations on soft clays without the need for additional supports such as log mats, gravel beds etc.

Under this category, soil stabilization depends mainly on chemical reactions between stabilizer (cementitious material) and soilminerals (pozzolanic materials) to achieve the desired effect. A chemical stabilization method is the fundamental of this review and, therefore, throughout the rest of this report, the term soil stabilization will mean
