Subsidance correction work | Resolving dizziness and seismic anxiety through floor tilt analysis and leveling of the home.
Scientifically analyzing floor inclinations that cause unexplained dizziness! Protecting structural resilience and health through perimeter level measurements and correcting subsidence while living in the building.
Health issues such as unexplained dizziness and headaches are caused by the slight tilting of floors due to ground subsidence, which places a constant load on the semicircular canals. Geotech's subsidence correction services clarify the relationship between building tilt and health problems, restoring the horizontal state and seismic performance of homes with advanced technology. First, we conduct precise level measurements around the building's perimeter using high-precision equipment, objectively analyzing and visualizing the amount of subsidence and deformation angles in millimeter units. Based on this diagnostic data, we plan and execute "subsidence correction while living," which requires no temporary housing or relocation. During construction, we protect living infrastructure and minimize resident stress through low-noise and low-vibration methods. Furthermore, we permanently prevent re-subsidence with a variety of correction options, such as the "i-LIFT method," which performs precise lift-ups through pressurized liquid injection, and the "Ganko Oyaji method," which powerfully reinforces the foundation structure with carbon fiber sheets. This not only protects the health of residents but also continuously enhances the seismic resilience of valuable residential assets.
basic information
The corresponding structures include various types of wooden, steel, and reinforced concrete single-family homes and small buildings. The survey methods employ high-precision laser levels for measuring building perimeter levels and SWS tests, quantifying tilt angles and deformation behavior to the millimeter. The construction methods include liquid pressure injection (i-LIFT method), steel pipe pile driving method, pressure slab method, and carbon fiber foundation reinforcement (Ganko Oyaji method). The optimal construction method is selected based on ground conditions and site environment. The construction equipment uses a small power unit designed for low noise and low vibration to consider the neighboring areas.

Applications/Examples of results
Improvement of physical ailments such as dizziness, headaches, and insomnia in residents caused by floor tilt. Restoration of door opening and closing issues, floor creaking, wall covering tears, and foundation cracks. Correction of subsidence and leveling in a living situation without moving or temporary housing. Correction of structural distortion in houses with reduced seismic performance and enhancement of the strength and rigidity of the foundation structure. Long-term prevention of re-subsidence and reduction of the risk of differential settlement during earthquakes, as well as measures against liquefaction, can be widely utilized for maintaining family health and preserving housing assets for a long time.
