Unexplained physical discomforts such as dizziness, headaches, and a feeling of floating are caused by the continuous stress on the balance function due to the minute multidimensional tilting of the floor resulting from building subsidence. At Geotech, we focus on the correlation between this structural distortion and bodily sensations, providing high-precision subsidence correction solutions based on digital technology. First, we use highly sensitive building perimeter level measurement devices and three-dimensional displacement sensors to measure and visualize the elevation differences around the building, the maximum amount of subsidence, and the deformation angles (whether it is a uniform tilt or a deformed tilt) in millimeter detail. Furthermore, we scientifically analyze ground behavior by comparing data from tests such as SWS tests. In the restoration process, we apply "subsidence correction work that can be done while living in the building," which does not require temporary housing or moving, allowing construction to proceed without disrupting living infrastructure. By combining our core technology, the "i-LIFT method" for precise digital lifting, with the foundation reinforcement technique "Ganko Oyaji method," we prevent further subsidence and accurately and swiftly restore a healthy and comfortable living space.
