A groundbreaking foundation method for soft ground, the Top Base Method.
The world's oldest wooden structure, Horyu-ji's five-story pagoda, has withstood wind, snow, and major earthquakes for nearly 1,400 years without experiencing differential settlement, maintaining its elegance and magnificent appearance. The principle of the "stone cushion method," which lays stones on the great foundation built by our predecessors, demonstrates excellent effects in modern civil engineering and construction by using the "top base method (my spinning top)." Additionally, it offers many advantages such as ground reinforcement, excellent economic efficiency, ease of construction, and high reliability, making it widely applicable in various foundation works. [Features] - Safely supports superimposed loads even on extremely weak ground - Durability can be expected due to vibration absorption and earthquake resistance - Controls settlement and prevents differential settlement - An environmentally friendly method with no underground contamination - Construction is also possible in confined spaces within buildings For more details, please contact us or download the catalog.
