In this document, we introduce the "SEP Method." As a quick reference for bearing capacity, we provide the end bearing capacities for four types of pile diameters: φ200, 250, 300, and 350 mm, as well as the frictional resistance per meter of the pile surface. Additionally, we include photographs of load tests, the extraction of piles, and construction examples. We encourage you to read it.

• Ground foundation construction method

The "SEP method" is a pile-type ground reinforcement technique aimed at small-scale structures. A soil-extraction suppression screw device is rotated and pressed into the ground, and after reaching a predetermined depth, cement milk mixed with SES is injected while pulling up the drilling rod, thereby constructing a replacement column. The pile diameter can be selected from φ200mm to 350mm, providing significant bearing capacity, and the applicable ground conditions range from sandy soil to clayey soil at depths of 1.5m to 10m. 【Features】 ■ Simple construction ■ Provides stability in quality ■ Gives significant bearing capacity to the foundation *For more details, please refer to the PDF materials or feel free to contact us.

• Ground foundation construction method

We would like to introduce our "SEP Method." By using a screw with a drum attached, we can suppress construction soil discharge. There is less sludge after replacement, which reduces industrial waste disposal costs. Additionally, since there are four patterns of reinforcement body diameters, we can select the size of heavy machinery according to the site, making it possible to accommodate both narrow and large sites. 【Features】 ■ Eliminates waste ■ Not limited by soil type ■ Large pile diameter and wide pile spacing ■ High molding accuracy ■ Shortened construction period *For more details, please refer to the PDF materials or feel free to contact us.

• Ground foundation construction method

Our company is a registered business for the "Ground Guarantee" warranty system. Properties for which we conduct ground surveys and ground improvement work will come with a 20-year warranty. Please feel free to contact us when you need our services. 【Features】 ■ A system that pays for the construction costs to restore the current condition ■ The warranty period starts from the foundation construction date and lasts for 20 years from the delivery date *For more details, please refer to the PDF materials or feel free to contact us.

• Ground foundation construction method

We would like to introduce the features and specifications of our "SEP Method." Since it does not mix with soil, it is not affected by soil quality and can be applied to loam layers and humus layers, eliminating the need for preliminary indoor mixing tests and hexavalent chromium leaching tests. Additionally, thanks to the specially shaped trough screw, it suppresses the generation of excavated soil (remaining soil) and allows for excavation even in interlayers where gravel layers are present. 【Features】 ■ Applicable to loam layers and humus layers ■ No need for preliminary indoor mixing tests and hexavalent chromium leaching tests ■ Suppresses the generation of excavated soil (remaining soil) ■ Allows for excavation even in interlayers where gravel layers are present *For more details, please refer to the PDF materials or feel free to contact us.

• Ground foundation construction method

The "SEP Method (Simple, Eco, Pile)" is a columnar ground reinforcement method that maintains a stable construction speed across a wide range of soil types with a simple work procedure. It generates minimal residual soil and reduces the need for soil transportation. Due to its screw excavation method, it is easy to construct even in hard intermediate layers and is applicable to humus soil and loam. Additionally, the drum-equipped screw compresses the excavated soil against the wall of the hole, reducing the amount of soil to be discharged. The excavated soil is generated on-site, making disposal easy. 【Features】 ■ Fast construction (shortened construction period) ■ Economic design possible with four different diameters ■ Wide range of applicable soil types ■ Reduction of discharged soil ■ As it is a method that does not mix with soil, hexavalent chromium does not leach out *For more details, please refer to the PDF materials or feel free to contact us.

• Ground foundation construction method

"Simple Eco Soda" is a mixing agent primarily composed of inorganic metal salts, functioning as a bleeding suppressant with thickening and early strength gain effects. It prevents cracking by retaining initial moisture. It allows for the construction of a stable, uniform reinforcement body with consistent strength. Additionally, by adding and kneading this agent into cement milk, it exhibits various effects such as bleeding suppression and stabilization of hole walls. 【Effects】 ■ Bleeding suppression ■ Hole wall stabilization ■ Cracking prevention ■ Acceleration of hardening speed ■ Environmentally friendly *For more details, please download the PDF or contact us.

• Concrete admixture
• Reinforcement and repair materials

Our company offers the "SEP Method," a pile-type ground reinforcement technique that enhances the molding accuracy of replacement columns, stabilizes strength, reduces quality variation, and suppresses deformation. This method involves rotating and driving a soil-extraction type screw device (Trowel Screw) into the ground. Once it reaches the specified depth, we inject cement milk mixed with "Simple Eco Soda" while pulling up the drilling rod, thereby constructing the replacement column and resolving traditional issues all at once. 【Features】 ■ Suppresses soil extraction ■ High-quality reinforcement body ■ Fast construction ■ Suitable for both narrow and large sites ■ High penetration capability *For more details, please download the PDF or contact us.
