Deep Soil Mixing - Berkel Company Contractors, Inc.

Deep Soil Mixing. 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. The columns are often installed in a block, grid or ...

Sep 19, 2018  Based on practical experiences, the small rectangular area is generally set to be about 20 m wide. Prior to construction, the soil in the small area is improved by the deep mixing method in a block type. The rectangular area thus functions like a rigid wall that can reduce the magnitude of soil and tunnel movements towards the excavation.
