First, we conduct high-precision measurements of the building's perimeter level, visualizing and analyzing the level differences and subsidence angles around the building in millimeter increments. Based on this objective data, we plan and execute "subsidence correction while living in the home," which requires no temporary housing or relocation. We protect the living infrastructure and carry out construction without disrupting the daily rhythms of children and families by using low-noise, low-vibration equipment and strict dust protection measures. Furthermore, we prevent re-subsidence with the "i-LIFT method" using pressurized liquid injection and the foundation reinforcement "Ganko Oyaji method." We are committed to safeguarding a healthy and secure living environment for the long term.

Differential settlement of the ground and floor inclinations not only induce unexplained health issues such as dizziness, headaches, and nausea in residents but also lead to a catastrophic drop in asset value during the sale of used homes and inspection assessments. GeoTech's settlement correction solutions achieve the simultaneous restoration of structural distortion, improvement of health issues, and maximization of residential asset value. First, we conduct high-precision measurements of the building's perimeter levels, detailing the height differences around the building, maximum settlement amounts, and deformation angles down to the millimeter. Based on this scientific data, we plan and execute "settlement correction while living" that eliminates the need for temporary housing or relocation. By maintaining living infrastructure and minimizing secondary costs, we significantly reduce both mental and financial burdens. Furthermore, we permanently prevent re-settlement using various techniques such as the "i-LIFT method," which performs precise lift-up through pressure injection of liquid, and the "Ganko Oyaji method," which strengthens the foundation structure. We are committed to protecting the healthy lives of residents and their valuable residential assets for the long term.

In the business of purchasing and reselling used homes or renovation projects, ground subsidence and floor tilting are significant risk factors that can lead to buyers withdrawing from the purchase or complaints about health issues such as dizziness and headaches after handover. GeoTech's subsidence correction solutions clarify the relationship between building tilt and physical stress, achieving both the regeneration of real estate value and the protection of residents' health simultaneously. First, we conduct precise level measurements of the building's perimeter using high-precision equipment, detailing and visualizing the height differences and deformation angles around the building down to the millimeter. Based on this scientific evidence, we plan and execute "subsidence correction while living in the home," which requires no temporary housing or relocation. This approach avoids secondary costs such as moving expenses and allows for a smooth progression of the buying, selling, or renovation schedule. Furthermore, we reinforce the foundation from the ground up using the "i-LIFT method," which involves precise lift-up through pressure-injected liquids, and the "Ganko Oyaji method," which strengthens the foundation structure. This prevents re-subsidence and significantly enhances market value as a high-quality home that fulfills accountability.

By using low-noise, low-vibration equipment and thorough dust control measures, we minimize the impact on customers and residents. Additionally, we strengthen the foundation from the ground up with precision lifting using the "i-LIFT method" and foundation reinforcement with the "Ganko Oyaji method." We are committed to protecting the health of your family and the stability of your business for the long term.

The sinking of buildings and tilting of floors caused by disasters such as earthquakes, liquefaction, and heavy rain is a serious issue that, in addition to the stress of being affected, can lead to unexplained dizziness, headaches, and nausea in residents, resulting in severe autonomic nervous system disorders. GeoTech's sinking correction service focuses on the relationship between structural distortion and biological stress after a disaster, providing solutions to quickly rebuild a safe and secure living environment. First, we conduct high-precision measurements of the building's perimeter levels, visualizing and data-collecting the height differences around the building, maximum sinking amount, and deformation angles in millimeter detail. Based on this objective diagnosis, which is also effective as evidence for disaster certificates and insurance claims, we plan and execute "sinking correction while living," eliminating the need to relocate to shelters or temporary housing. We protect living infrastructure, reduce secondary costs, and alleviate residents' anxieties. Furthermore, we block the risk of re-sinking and re-disaster through precise lift-up using the "i-LIFT method" with pressurized liquid injection and the "Ganko Oyaji method," which reinforces the foundation structure. We are committed to protecting the health and homes of affected families for the long term.

The uneven settlement of residential buildings and the tilting of floors due to aging can cause persistent stress to the vestibular system and autonomic nervous system of the residents, leading to unexplained symptoms such as dizziness, headaches, and nausea. The settlement correction work provided by Geotech Co., Ltd. is an advanced technology that fundamentally resolves these unpleasant symptoms and restores a healthy living environment in homes. Before construction, laser measuring devices and leveling instruments are used to visualize the tilt of the building's exterior and interior in millimeter detail, and optimal repair designs are planned based on objective technical data. During the actual correction work, low-noise and low-vibration multi-stage hydraulic jacks are used to accurately lift the tilted foundation structure to a horizontal state, utilizing the weight of the building and ground reaction forces. This process does not require any relocation to temporary housing, allowing the construction to be completed while maintaining essential living infrastructure such as water and gas, thus avoiding unnecessary secondary costs and mental burdens. After construction, resin injection into foundation cracks and air milk filling into ground voids are carried out to ensure permanent stabilization and prevention of re-settlement.

Claims regarding defects in residential properties and issues such as differential settlement and floor tilt that arise during inspections not only lower the value of the building but also cause residents to experience autonomic nervous system disorders such as dizziness and tinnitus. GeoTech Co., Ltd. provides settlement analysis based on objective evidence and high-precision settlement correction solutions. In preliminary investigations, we conduct screw weight penetration (SWS) tests and laser measurements around the building's perimeter to quantify soil properties, ground resistance values, and deformation angles, scientifically clarifying the factors contributing to settlement. During the restoration process, we utilize a low-noise, low-vibration hydraulic jack system to perform precise leveling corrections in millimeter increments without putting stress on the building's structure, all under continuous digital monitoring. This allows construction to proceed while residents remain in the property, thoroughly eliminating secondary costs such as temporary housing expenses and moving. After the corrections, we ensure load-bearing capacity through the installation of steel pipe piles and pressure plates, and by injecting air milk and resin into foundation cracks, we achieve lasting structural safety and enhancement of asset value.

In uneven ground where narrow plots are close to property boundaries and mixed with embankments and excavations, localized subsidence can cause houses to tilt, leading to unexplained dizziness, headaches, and autonomic nervous system disorders for the residents. GeoTech's subsidence correction method is an advanced technology that protects both the building and the health of its occupants from the ground up, even in harsh construction environments. During site surveys, the distribution depth of soft layers and the deformation angles of foundations are accurately analyzed through screw weight penetration (SWS) tests and peripheral level measurements. In actual repairs, we utilize a steel pipe pile driving method (underpinning) using small hydraulic jacks and the i-LIFT method, which injects non-dispersive cement-based grout. Even in narrow sites where large machinery cannot enter, we perform millimeter-level horizontal corrections without relocating to temporary housing, while continuing to use essential utilities such as water and gas. After correction, high-density bubble mortar (air milk) is injected into the ground voids, and for foundation cracks, resin injection and carbon fiber sheet application are carried out, providing strong footing stabilization along with high seismic resistance and extended lifespan.

This catalog explains a sinking correction method that addresses the often-overlooked floor tilt during renovations, fundamentally improving residents' dizziness and health issues. Subtle floor inclinations caused by uneven ground subsidence can chronically stress the semicircular canals, leading to autonomic nervous system disturbances and headaches. Our company objectively clarifies the causes of subsidence through precise level measurements around the building and Swedish sounding (SWS) surveys. During construction, we carefully lift the building while monitoring its displacement in millimeter increments in real-time, using small hydraulic jacks. By employing low-noise equipment that minimizes operational sounds and vibrations, we can restore the level state within a short period without requiring residents to leave their familiar homes or move to temporary accommodations. Furthermore, by combining steel pipe pile driving into deep supporting layers and filling voids under the foundation, we thoroughly prevent future subsidence. We propose technology that enhances the structural safety of homes and realizes a safe and healthy living environment.

This document is a technical material that clearly explains the sinking correction work to rectify floor tilts, which can be a bottleneck in used housing transactions and renovation proposals, thereby resolving dizziness issues for residents and enhancing the asset value of the building. Millimeter-level floor tilts caused by uneven ground subsidence can create illusions in the human vestibular system and semicircular canals, leading to chronic dizziness, headaches, and other health problems. At Geotech, we conduct building perimeter level measurements using high-precision levels and SWS tests to objectively visualize the degree of subsidence and ground conditions as digital data. For tilt correction, we apply a low-noise hydraulic jack method that utilizes the building's own weight as a counterforce, allowing for precise leveling without placing excessive burden on the superstructure. Even in narrow sites where large machinery cannot enter, we can safely carry out the work in a short period while residents remain in the building. After restoration, we prevent re-subsidence through the insertion of steel pipe piles and the injection of bubble mortar, and we also accommodate the reattachment of ground guarantees. This strongly supports the reliability of real estate transactions and renovation work.
