SAT column method

Quickly construct columns with a safe and robust deep mixing method! High-quality columns can be created in sandy soil, clay, loam, and other ground types. *Building technology performance certification obtained.

This construction method is a mechanical mixing deep mixing treatment method that creates columnar ground improvement bodies by excavating and mixing the ground while discharging a slurry of cement-based solidifying material. It has a maximum design strength of Fc=2,500KN/m2, which is high strength, and the dedicated special mixing machine has high mixing efficiency, allowing for the creation of high-quality columns in sandy soil, clayey soil, loam, and other ground types. **Features of the SAT Column Method** - Building technology performance certification GBRC No. 18-28 - Use of a dedicated mixing machine for the SAT column method - Supports various improvement forms according to purpose, including pile type (pile arrangement, circular arrangement, lap arrangement), block type, and wall type - Thorough management system with real-time management devices to construct safe and robust columns - Capable of selecting equipment from small to large heavy machinery and related equipment to accommodate a variety of sites, including buildings, civil engineering structures, and temporary structures - Achieves low cost with a lineup of solidifying material amounts with a reduced increase factor (variation coefficient of 25%) and improvement diameters ranging from φ400 to 1600mm *For more details, please download the PDF document or feel free to contact us.*
