We have launched "Yōbi Daisekken.com," where you can easily obtain the "estimated construction costs" and "cross-sectional CAD data" for retaining wall structures. Currently, "Yōbi Daisekken.com" provides information on the tail-arm method and EDO-EPS (expanded polystyrene civil engineering method), and we will continue to expand our services as a comprehensive platform to offer various reinforcement soil methods, cross-sectional drawings of retaining wall structures, and estimated construction costs. We will continue to enhance the content, so please make use of "Yōbi Daisekken.com."
