New proposal for deep ground improvement! A method adaptable to various soil types from sandy soil to loam.
The "Esmi Column Method" is a construction technique that adapts to various soil types, from sandy soil to clay and loam, without being limited by soil quality. There are three types of special mixing blades designed to enhance construction accuracy, including eccentric types that prevent the phenomenon of mutual rotation and reverse drive types. We offer a range of machines, including single-shaft, double-shaft, and mini sizes, allowing for construction tailored to the size of the site. 【Features】 ■ Creation of high-strength column bodies ■ Ability to record construction data for future reference ■ Environmentally friendly construction method ■ Construction process that delivers high quality ■ Abundant case studies and diverse construction achievements For more details, please refer to the catalog or feel free to contact us.

basic information
**Properties of Improved Esmi Columns** ■ Shape - Columns with a diameter of 600 to 1,600 mm can be constructed - Construction depth can reach approximately 20 m ■ Strength - Uniaxial compressive strength of up to 2 N/mm² can be achieved (varies depending on soil type and the amount of cement-based solidifying agent added) - Shear strength is approximately 1/3 to 1/5 of the uniaxial compressive strength ■ Durability - Using a cement-based solidifying agent ensures that the column maintains a stable condition over the long term *For more details, please refer to the catalog or feel free to contact us.*
