Company information
The construction industry has often focused on large-scale projects until now. However, moving forward, we must not only create new things but also harmonize with the limited natural environment. Our company is currently putting effort into new areas such as the development of bubble-mixed lightweight fill, fluidized treated soil, recycling of construction-generated soft soil and high-water-content clay, and cavity filling materials.
