Subsidence correction work | Cure the cause of dizziness with floor tilt analysis and leveling of the home.
Subsidance correction work
Scientific numerical analysis of floor inclinations causing unexplained dizziness! Restoring a comfortable living space while living in it through building perimeter level measurement and non-destructive modifications.
Unexplained physical discomforts such as dizziness, headaches, and a feeling of floating are caused by slight tilts in the floor due to differential settlement of the building, which puts unpleasant stress on the semicircular canals and balance sense. At Geotech, we focus on the correlation between structural distortion and physical discomfort, providing settlement correction solutions based on advanced numerical data. First, we conduct high-precision measurements of the building's perimeter levels, analyzing and visualizing the height differences around the building, maximum settlement amounts, and deformation angles (whether it is a uniform tilt or a deformed tilt) to the millimeter. Additionally, we identify ground behavior by combining investigations such as SWS tests. In the correction process, we apply "settlement correction while living" that does not require temporary housing or moving, allowing us to carry out construction without disrupting living infrastructure. Our core technology, the "i-LIFT method," integrates the formation of support plates and precise lift-up through pressurized injection of liquid into the deep ground. By combining this with the foundation reinforcement method "Ganko Oyaji," we prevent re-settlement in advance, scientifically restoring a safe, secure, and comfortable living space.

basic information
The applicable targets are general single-family homes, apartments, and various small-scale building structures. Survey methods include automatic levels, laser measuring devices, displacement sensors, and SWS testing machines to quantitatively evaluate tilt angles, deformation angles, and bearing capacity characteristics. For settlement correction techniques, we offer a lineup that includes pressure injection of quick-setting cement-based grout (i-LIFT method), steel pipe pile driving method, and pressure-resistant slab method. The injection materials are non-toxic and non-dispersive, avoiding groundwater contamination. Furthermore, as a measure to improve foundation rigidity, we support foundation reinforcement methods that involve attaching and molding high-strength carbon fiber sheets (Ganko Oyaji method).

Applications/Examples of results
Precision leveling correction of floor inclinations in millimeter units due to building settlement and differential settlement. Improvement of health issues such as dizziness, headaches, and feelings of floating caused by tilting. Repair and durability enhancement of opening cracks and structural cracks in exterior walls and foundation concrete. Non-destructive settlement correction in occupied buildings where moving or temporary housing is not possible. Seismic and shear reinforcement of unreinforced foundation houses that have aged. This can be utilized for various purposes, from addressing health damage in homes to structural preservation, including prevention of future settlement and ground consolidation settlement risks.
