For weak ground and vibration/seismic measures! An evolved form of ground improvement that protects lives and assets.
The ground replacement method "Columbus(R)" is a technique that is resistant to differential settlement, earthquakes, and liquefaction. By removing the soil beneath the foundation of buildings constructed on weak ground and laying down EPS (expanded polystyrene) "geofoam," the balance between the ground and the building load is adjusted, protecting the building from differential settlement and vibrations. Recent earthquakes have demonstrated that this method is effective not only against differential settlement and vibrations but also against earthquakes and liquefaction, attracting further attention. 【Features】 ■ A simple concept of "replacing" the ground ■ A method made possible by the lightweight and strong "geofoam" ■ Effective not only against differential settlement but also against earthquakes and liquefaction ■ Designed with consideration for load distribution and ground balance *For more details, please download the PDF or contact us.

Company information
Since our establishment, we have introduced new technologies to respond to the diversifying construction projects and have contributed to society through foundation construction for a quarter of a century. The importance of structural foundations was re-evaluated during the Great Hanshin Earthquake in January 1995. In this context, we aim to achieve comprehensive consulting on "soil and foundations." Please feel free to contact us if you have any inquiries.
