This is a low-cost, high-precision subsidence correction method that repairs building subsidence accompanied by foundation cracks without waste, based on scientific diagnosis through SWS (Screw Weight Penetration) testing and precise level measurement. It accurately analyzes ground resistance values and the distribution of weak layers at multiple points within the site to investigate the true causes of subsidence. For the foundation structure damaged by subsidence stress, high-viscosity epoxy resin is pressure-injected to seal and repair cracks, restoring bending strength and seismic resistance to levels exceeding those of new construction. In the lifting process, pressure plates are concentrated under the foundation in the subsidence area, and small hydraulic jacks are linked with high-precision laser measuring devices to carry out millimeter-level precise leveling adjustments. After jacking up, high-density air-mortar (air milk) is injected into the gap between the foundation and the ground to densify it, preventing future risks of re-subsidence. Since it can be constructed with minimal excavation and partial jacking adjustments, it does not incur excessive construction costs and safely and reliably resolves tilting issues in a short period while residents remain in the building.

This is a reliable home repair solution that allows you to safely and neatly repair building subsidence with foundation cracks while living in your familiar home. Since there is no need for moving or securing temporary housing, you can significantly cut unnecessary secondary costs and efforts, which can range from several hundred thousand to several million yen. High-viscosity epoxy resin is injected densely into the damaged foundation structure due to subsidence stress, firmly bonding and reinforcing the cracks to improve structural strength and waterproofing. In the lifting process, a compact pressure plate and hydraulic jacks are set under the foundation, and the building's behavior is monitored with high-precision laser measurements to accurately correct the tilt in millimeter increments. By using quiet equipment that minimizes noise and vibration, and thoroughly implementing dust prevention measures to keep dust from entering the interior, the construction can be completed in a short period without compromising the comfort of remote work or daily life. After the jacking up, air milk is filled at the base to prevent re-subsidence, and we provide consistent support until the ground warranty is reattached, delivering the highest sense of security to the homeowner, even better than at the time of new construction.

This is a reliable settlement correction plan that aims to quickly resolve foundation cracks and partial subsidence issues that occur in newly built homes after handover, with the utmost consideration from the construction company and house manufacturer towards the homeowner. For foundation cracks caused by uneven ground or soil consolidation, high-viscosity epoxy resin is pressure-injected to ensure adhesion and waterproofing of the structure. In the lifting process, pressure plates are concentrated directly beneath the foundation, and using small hydraulic jacks and high-precision laser measurement, precise leveling is performed in millimeter increments, using the building's own weight as a counterforce. After the jacking is completed, air bubble mortar is injected at high density into the voids beneath the foundation to establish surface support and prevent future subsidence. The construction can be carried out while the homeowner is still living in the house, eliminating the need for temporary relocation and reducing secondary costs and mental burden for the homeowner. By providing consistent support through the process of reattaching ground guarantees after construction, we fulfill our responsibility for defect handling and strongly support the rebuilding of trust through aftercare.

This is a subsidence correction technology that safely and with low vibration resolves partial subsidence issues accompanied by foundation cracks in densely populated residential areas and narrow sites adjacent to property boundaries. For foundation cracks caused by excavation on neighboring land or lateral flow of fill, high-viscosity epoxy resin is injected densely to strongly bond and reinforce the broken structure, restoring structural rigidity and waterproofing. In the lifting process, it accommodates narrow sites where large machinery cannot enter by concentrating compact, high-strength steel pressure plates directly under the foundation. Using small hydraulic jacks and high-precision laser measuring instruments, the building's weight is used as a reaction force to carefully lift it millimeter by millimeter, returning it to a precise horizontal state without affecting neighboring houses. After correction, self-hardening lightweight bubble mortar (air milk) is poured into the voids under the foundation to densify it, expanding the contact area to prevent re-subsidence. With construction carried out while residents are living in the home, eliminating the need for temporary housing, and thorough low-noise and dust control measures, it minimizes neighborhood disputes while protecting the structural stability and asset value of the home.

This is an advanced settlement correction solution that resolves foundation cracks and partial subsidence issues identified in used housing transactions and inspection surveys, dramatically enhancing the value of real estate assets. For foundation cracks caused by uneven ground, high-viscosity epoxy resin is pressure-injected to integrate and reinforce the structure, restoring seismic strength and waterproofing to the level of new construction. For correcting tilting, high-strength pressure plates and hydraulic jacks are installed beneath the foundation, allowing for precise millimeter-level horizontal lift-up while monitoring displacement with high-precision laser measuring devices. It effectively resolves issues with door operation and floor inclinations, ensuring compliance with building inspections and mortgage review standards. After lifting, bubble mortar (air milk) is filled and compacted beneath the foundation to prevent re-sinking, providing consistent support until the ground warranty is reinstated. With rapid construction that does not require temporary housing, it minimizes the burden on homeowners during pre-sale renovations or post-purchase repairs before handover, strongly supporting the smooth completion of real estate transactions.

This is a high-precision settlement correction solution that fundamentally addresses the problem of uneven ground and differential settlement associated with foundation cracking in residential areas close to retaining walls and embankment/cut boundaries. For the foundation concrete structure that has fractured due to uneven loading, high-viscosity epoxy resin is injected densely to bond and repair the cracks, restoring structural rigidity and waterproofing to the level of new construction. In the lifting process, a thick steel plate pressure distribution slab and hydraulic jacks are set directly under the foundation, and real-time monitoring of the building's behavior is conducted using high-precision laser measurement, allowing for accurate horizontal correction in millimeter increments. After lifting is complete, lightweight bubble mortar (air milk), which has excellent fluidity, is filled into the voids beneath the foundation to densify it, expanding the contact area to support the building's weight over a larger surface and strongly preventing future re-settlement. This method can be implemented even in areas near retaining walls or in narrow spaces where large machinery cannot be brought in, and by accommodating construction while residents are living in the property without the need for demolition or temporary housing, it dramatically reduces secondary expenses and living stress for the homeowners.

GeoTech proposes the "i-LIFT Method," a pre-subsidence prevention technique using pressure-injected chemical solutions for existing homes facing the risks of liquefaction and uneven settlement during earthquakes.
