Ground improvement measures are possible with the ground replacement method "Columbus+" / Commercial facility case study.

basic information

【Features】 ○ The cushioning material, "Geofoam," "reduces vibrations from traffic and machinery," and "reflects and absorbs seismic tremors," thereby weakening the impact transmitted to the foundation concrete, resulting in a reduction of vibrations felt in the building by half. ○ The weaker the ground, the longer and larger the seismic 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) manufactured using the bead foaming method. ○ 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.
