Ground improvement measures are possible with the ground replacement method "Columbus+" / Case study of welfare facilities.

basic information

【Features】 ○ The cushioning material "Geofoam" weakens the "vibrations from traffic and machinery" and "reflects and absorbs earthquake tremors," thereby reducing the impact transmitted to the foundation concrete, resulting in a halving of the vibrations experienced by the building. ○ The weaker the ground, the longer and larger the earthquake tremors become. ○ In the case of the ground replacement method [Columbus+], as a result of measures against weak ground, a double effect of differential settlement countermeasures and seismic isolation is achieved. ○ The insulation properties of the "Geofoam" installed under the entire foundation reduce heat loss to the underfloor, contributing to CO2 reduction through heat storage heating systems that store heat in the foundation concrete. 【What is Geofoam?】 ○ It is expanded polystyrene (EPS) produced by the molding method using polystyrene beads. ○ EPS was first used in ground applications in 1972 with the development of the "EPS Civil Engineering Method" in Norway. ○ In Japan, it was introduced in 1986, and it has been confirmed to be durable without issues such as corrosion from microorganisms in the soil or damage from termites. ● For more details, please contact us or download the catalog.
