Excavated soil is natural soil! A reliable method for constructing expanded bulb foundations through the middle excavation and reinforcement technique.
The "STJ Method" is a construction technique that involves high-pressure injection of cement milk from an STJ bit to create an enlarged bulb, integrating it with the ground to develop bearing capacity. By switching the auger's rotation to a low speed and jetting cement milk from two high-pressure injection nozzles while pulling it up at a constant speed, it is possible to reliably construct an enlarged bulb. Compared to the pre-boring method, it is a low-discharge method, and the discharged soil is natural soil, contributing to a circular economy. 【Features】 ■ Low noise and low vibration method ■ Reliable construction of enlarged bulbs ■ High bearing capacity ■ Rapid construction ■ Low construction costs *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Our company is engaged in the manufacturing, sales, and design construction of concrete piles. In recent years, our country has experienced frequent earthquake disasters, and as a concrete pile manufacturer that supports various structures from below ground, we have established a consistent system from manufacturing to sales and construction. We are adopted as a "foundation" that supports your valuable assets with reliable quality and excellent technology. Additionally, besides our own products, we handle ground surveys, various ground improvements, and steel pipe piles, proposing the best "foundation" to meet needs ranging from residential to large-scale construction. In a challenging environment surrounding society, we will contribute to the community and society through what only our company can do.
