Ground improvement helps increase shear strength of soils, modify the ground to bear the weight of the structure we build. The recent Kumamoto earthquake left with many damages of tilting buildings. Therefore, there is an increasing awareness of foundation improvement not only in Kumamoto but also in the whole country. Usami Kogyo has tackled many problems in ground improvement using natural crushed stone (HySPEED technology). This is the ideal solutions since it does not only strengthen the ground, but also unharm the environment and protect your properties.
