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.*

The "TSC Method" is a mechanical deep mixing treatment method that constructs a ground improvement body by injecting cement-based solidification material slurry into the ground while mixing and stirring it with the original ground from the tip of a special excavation and mixing device equipped with TSC bars. The need for long-term stability of foundations for buildings and structures has led to this method, which solidifies soft ground in a cylindrical shape, obtaining "Construction Technology Review Certification." 【Features】 ■ TSC Method diffusion wings (patent pending) ■ By using a dedicated excavation and mixing device for this method, the phenomenon of soil co-rotation is suppressed - Improves mixing performance to create high-quality solidified bodies ■ Two-way stirring is the standard construction cycle ■ Real-time management is possible using construction management devices For more details, please feel free to contact us.

■ High penetration input The dedicated screw can drill even with a hard layer in the middle. ■ Suppression of soil discharge The dedicated screw with a drum suppresses soil discharge, reduces industrial waste, and is an eco-friendly construction method. ■ High-quality reinforcement body By simply replacing local soil with cement milk, it is not affected by soil quality, allowing for the construction of a high-quality reinforcement body. ■ Short construction period Breathing is suppressed with a dedicated admixture, enabling construction in a short period. ■ From narrow sites to large-scale projects Heavy machinery suitable for the site and four patterns of reinforcement body diameters are selected, allowing for economical design.

The "Pure Pile Method" is a foundation reinforcement technique for single-family homes that solidifies cement milk into pile shapes underground, demonstrating high quality and high load-bearing capacity regardless of soil type. The construction procedure involves only one round of excavation and filling, allowing for fast construction speed and the creation of high-quality columns. By adopting a conical excavation head, the risk of soil clumping contamination during excavation has been eliminated. 【Features】 - Does not mix cement milk with the ground - The quality of the pile-shaped columns is not affected by soil type at all - Can be applied even in humus soil where solidification is difficult with conventional column improvement methods - Due to the principles of the construction method and procedure, the ground is not loosened, resulting in high vertical load-bearing capacity - Straight rods or spiral rods can be used according to soil type - Since straight rods do not have a soil discharge mechanism, there is almost no generated residual soil For more details, please feel free to contact us.

**Features of Tecot Piles** ■ Highly Reliable Piles Tecot Piles - Driven piles certified by the Minister of Land, Infrastructure, Transport and Tourism, Japan Architectural Center TACP-0355 TACP-0356 Tecot Pile SR - Driven piles certified by the Japan Architectural Comprehensive Testing Institute GBRC-10-08 ■ High Load-Bearing Capacity Adopts a tip wing diameter of 250 to 650 mm with a load-bearing coefficient α = 270 ■ Reliable Quality Control Conducts slide weight tests to confirm the load-bearing capacity of the pile tip ■ Environmentally Friendly Since it is installed by rotary penetration, construction can be done without residual soil, generating no industrial waste. ■ Low Cost In addition to standard round steel pipes, square steel pipes are also used, enabling low costs.

■ Performance-Proven Construction Method Building Technology Performance Certification GBRC Performance Certification No. 13-04 Rev. 2 This method has been reviewed by a third-party organization, which certifies the performance of the technology. ■ High Load-Bearing Capacity and High Strength This method combines the benefits of steel pipes with stable quality and strength of columnar improvement bodies. ■ High-Quality Mixing The specialized mixer, equipped with a comb section and eight blades, provides high-quality mixing. ■ Wide Range of Soil Types This method can accommodate a wider range of soil types than typical columnar improvement methods, as the steel pipes can complement quality and strength to mitigate variations in strength due to soil type. ■ Short Construction Period Due to high surface friction and quality, it is possible to shorten the pile length compared to conventional columnar improvement methods, leading to a reduction in construction time. ■ Suitable for Narrow Sites Heavy machinery is selected based on site conditions to advance the project more efficiently.

The "Soil Bag Method" is an environmentally friendly foundation reinforcement technique that does not use any solidifying materials, including cement, by utilizing the "D·Box." The "D·Box" generates significant friction between soil particles, providing various effects such as ground reinforcement, vibration reduction, and liquefaction countermeasures. In particular, it can compact itself regardless of ground reaction, allowing for reinforcement effects even in extremely soft ground such as marshes, which are typically considered difficult. 【Features】 ■ The D·Box is completely permeable to water, so it does not affect the underground environment when installed in the soil. ■ Since the D·Box essentially just encapsulates soil particles, it can reduce CO2 emissions. ■ It has effects equivalent to surface improvement, allowing for efficient ground reinforcement construction. ■ It simultaneously achieves ground reinforcement and vibration reduction, offering excellent cost-effectiveness. ■ It can increase the strength of the surrounding ground where the D·Box is installed.
