The "Epocolumn Method" is a ground improvement technique that enables the construction of high-quality columns by mixing slurry and soil in three-dimensional space through a composite relative agitation, where the outer wings, middle wings, and core wings of a cage-like structure intersect and rotate in different directions. With a highly rigid stirring wing shape fixed at both ends to the rotation axis and high torque performance, this method allows for ground improvement construction directly on hard ground or mixed gravel and cobble ground without the need for auxiliary methods, which were previously difficult. 【Features】 ■ Prevents the phenomena of "dragging" and "co-rotation" of the ground ■ Capable of constructing large-diameter columns ■ Excellent mixing performance for cobbles and gravel layers ■ Maintains good vertical accuracy of the pile core ■ Slurry discharge can be selected from the tip discharge port and the circumferential discharge port For more details, please refer to the catalog or feel free to contact us.

The "Esmic Method" is a construction technique that uses various types of cement, lime, and cement-based solidifying agents to add and mix powder or slurry into soft soil, thereby solidifying and improving the shallow ground. It creates a strong and uniform improved body, ensuring the stability of structures and the ground. Depending on the method of adding the improving agents, it can be broadly classified into the "Esmic Base Method," which primarily uses powder, and the "Esmic Slurry Method" and "Esmic Mud Method," which primarily use slurry. 【Features】 - Wide applicability from improving soft ground to sludge treatment - Simple construction from material spreading to mixing, leveling, and compaction (powder mixing method) - High affinity with soil, preventing dust generation in the surrounding environment (slurry utilization method) - Unlike deep ground improvement, large pile driving machines are not required - Excellent workability and economically advantageous For more details, please refer to the catalog or feel free to contact us.

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.

The "WILL Method (Slurry Oscillation Mixing Method)" is a construction technique that forcibly mixes slurry-like solidifying materials and improved materials with in-situ soil using a special mixing blade attached to the tip of a backhoe-type base machine, thereby forming a stable improved body. By utilizing two types of ribbon screw mixing blades, this method can accommodate not only soft, viscous soil layers but also dense sandy soil layers and gravel layers with an N value exceeding 30. Additionally, by selecting the appropriate base machine, it can handle medium-depth improvements of approximately 13 meters. 【Features】 ■ Construction of high-quality improved bodies [Patent No. 4038525] ■ High excavation performance [Patent No. 3958347 & Patent No. 4829385] ■ Reduced environmental impact ■ High mobility and safety ■ Reliable quality control [Patent No. 4954166] For more details, please refer to the catalog or feel free to contact us.
