Achieve overwhelming ground support strength with reliable stop management. High support strength at a low cost! 【*Comparison materials of 10 major manufacturers available!】
The "Kenma Pile" is a pile that places the highest importance on penetration and constructability. Based on the experience, technology, and achievements we have cultivated so far, the wing shape of the Kenma Pile was developed to improve penetration into intermediate hard layers. Furthermore, by achieving 100% effective cross-sectional area in the wing, we realize high bearing capacity and low cost. 【Features】 ■ A pile that prioritizes penetration and constructability ■ Achieves industry-leading pull-out force κ65 ■ Enables size reduction design without considering the diameter of the pile shaft, achieving low cost ■ Reliable and easy-to-understand termination management method *For more details, please download the PDF materials or feel free to contact us. *We are also recruiting agents for the "Kenma Method."

Company information
Our newly developed "Kenma Pile (Rotary Driven Steel Pipe Pile)," which we have arrived at through extensive experience, serves as a reliable support in Japan's construction industry as a "non-extractable pile" and an "earthquake-resistant pile." We also aspire to utilize this technology to contribute to society. We are a company that creates tomorrow by contributing to society through steel pipe pile foundation work. That is us, Ikki Co., Ltd.
