This is a pile-type ground reinforcement method targeting small-scale structures!

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.

basic information

【Solving Such Issues with Conventional Methods】 ■ Log Pile Method - Pre-excavation is necessary when there is a hard intermediate layer - Difficult to drive in gravel mixed layers - Not applicable in sandy soils where the groundwater level fluctuates and log piles may corrode - Piles over 4m require splicing, leading to poor workability - Unstable distribution of log piles ■ Columnar Improvement Method (Deep Mixing Method) - Construction speed significantly decreases with hard intermediate layers - Slurry mixed residual soil is generated, requiring industrial waste disposal - Generally results in higher construction costs *For more details, please download the PDF or contact us.
