Soft ground countermeasures are possible: Ground replacement method "Columbus+" factory case study.

basic information

【Features】 ○ The cushioning material "Geofoam" weakens "vibrations from traffic and machinery" and "reflects and absorbs seismic tremors," thereby reducing the impact transmitted to the foundation concrete, resulting in a halving of the vibrations experienced by the building. ○ Weaker ground tends to experience longer and larger seismic vibrations. ○ In the case of the ground replacement method [Columbus+], the measures for weak ground result in a double effect of preventing differential settlement and providing seismic isolation. ○ The insulation properties of the "Geofoam" installed under the entire foundation reduce heat loss to the crawl space, contributing to CO2 reduction through thermal storage heating 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 has been confirmed to be durable, with no issues related to corrosion from microorganisms in the soil or damage from termites. ● For more details, please contact us or download the catalog.
