This is a subsidence correction work for buildings that have experienced differential settlement, aimed at restoring tilted houses. In the pressure plate method, a pressure plate (steel plate) is installed on stable ground, and the tilt of the building is precisely corrected using adjustment jacks and other tools. After the correction through jack-up, strong measures such as fixing with adjustment wheels, backfilling, and mortar filling are carried out to properly support the building's load and restore a safe living environment.

We provide settlement correction work to restore tilted houses that have experienced differential settlement. In the most commonly used steel pipe pile driving method, the building's load is used as a reaction force to drive steel pipe piles into the supporting ground using jacks, thereby supporting and correcting the entire building. This method not only corrects the settlement of the building but also prevents further settlement. Additionally, we select and implement the most suitable method from options such as pressure slab method, building relocation and new pile construction, and cement milk injection method, according to the ground conditions and the state of settlement.

The decision on the method for settlement correction and its implementation will be made based on a site survey, taking into consideration the following points: - Site conditions (slope situation, condition of existing structures, foundation and exterior conditions, ground data, buried objects, etc.) - Whether the settlement is ongoing or has stabilized. - Whether to carry out a full correction under the foundation (for the purpose of preventing re-settlement) or a partial correction.

The tilting and sinking of buildings occur due to insufficient ground support caused by topographical and human factors, and there has been a tendency for this to increase in recent years. i-LIFT method (i-LIFT construction method) patent application: 2003-430063

Additionally, construction can be carried out with compact machinery, making it feasible even in areas with limited space between adjacent houses. This method allows for a reduction in construction time compared to conventional methods. 【Features】 ■ Fine adjustments to the level are possible ■ Construction is possible in areas with limited space between adjacent houses ■ Reduction in construction time ■ Can be implemented even if ground improvement has already been performed ■ Can be applied to measures against ground subsidence *For more details, please refer to the PDF materials or feel free to contact us.*

We provide settlement correction work based on advanced engineering for buildings that have experienced differential settlement. Using the most proven method, the "steel pipe pile driving method," we reliably drive steel pipe piles to the supporting ground using hydraulic jacks, with the weight of the building serving as the reaction force, thereby supporting and correcting the entire structure. This method not only allows for precise horizontal correction of severe tilting but also possesses high durability to prevent future re-settlement. Additionally, based on the engineering analysis of the ground and settlement conditions, we select the optimal method from a variety of options such as "pressure slab method," "building relocation and new foundation pile construction," and "cement milk injection method," ensuring a reliable solution is implemented.

This method involves injecting grout (injection material) into the ground to lift and restore tilted or sunken buildings while simultaneously enhancing the ground's bearing capacity. The method consists of three "i (injection)" processes. First, repeated injections are made to form a "support plate" on the supporting layer. Next, injections are made beneath the foundation to create a "lift plate." Finally, "lift-up injection" is performed between the support plate and the lift plate to precisely raise the entire building. Utilizing laser measurement devices and computer-controlled three-dimensional tilt measurement systems, the tilt is continuously measured in real-time, allowing for precise leveling adjustments, making this a highly accurate, reliable, and safe construction technique.

This is a carbon fiber reinforcement system for existing concrete strip foundations that has obtained housing disaster prevention technology evaluation (evaluation number DPA-Housing Technology-23) from the Japan Architectural Disaster Prevention Association and has been registered as a utility model. By firmly adhering high-strength carbon fiber sheets to the foundation surface using matrix resin, it significantly improves shear strength, ductility, and seismic resistance. Unlike traditional underpinning methods that face many challenges in terms of weight, construction period, and cost, this system can reliably restore existing foundations with no reinforcement or deteriorated cracks to a robust supporting structure that far exceeds the original strength at the time of construction, without significantly changing the weight or cross-section of the structure.

This is a specialized document that clearly summarizes the overall plan for the jack-up construction of single-family homes to maintain the residents' living conditions. It covers advanced methods for correcting uneven settlement in wooden houses without the need for moving to temporary housing or relocating belongings, allowing for precise correction of building tilt down to the millimeter while residents remain in their homes. Utilizing a computer-controlled hydraulic jack system linked to high-precision laser measuring devices, the building is safely lifted to a horizontal line without imposing undue deformation stress on the structure. The plan includes meticulous project management that considers limited construction hours, reliable dust protection, and attention to vibration and noise, enabling the completion of work without disrupting daily activities such as remote work, house chores, and childcare. It dramatically alleviates health issues caused by floor tilt, such as dizziness, headaches, and insomnia, while simultaneously repairing issues like malfunctioning doors and windows and wall cracks. This comprehensive construction plan also includes measures to prevent re-settlement through the insertion of steel pipe piles beneath the foundation, minimizing the psychological and economic stress for the client.

Localized subsidence and cracking occurring in the fabric foundation of a residence are serious structural defects caused by localized weakening of the ground or uneven soil pressure due to neighboring embankments or excavations. If left unaddressed, the building's tilt will progress, leading to significant disruptions in daily life, such as wall cracks and malfunctioning window frames. In GeoTech's subsidence correction work, we employ a steel pipe pile driving method that uses hydraulic jacks to vertically press steel pipe piles into a hard support layer deep below the surface, utilizing the building's own weight as a reaction force. Piles are precisely placed at specific locations where localized subsidence has occurred, and the building is accurately jacked up to restore it to a level state. Additionally, cracks in the foundation are treated with epoxy resin injection or U-cut repairs, and ground fissures or voids beneath the floor are filled with high-density air milk, thoroughly reinforcing the overall stability of the structure and the strength of the foundation. The work can be carried out while residents remain in the building, with low vibration and low noise. This is the optimal method for resolving fabric foundation issues at low cost and in a short construction period, regardless of the building's age.

In residential land development, there are many cases where uneven ground, such as backfilling behind retaining walls and the intersection of cut and fill, leads to ground consolidation settlement and differential settlement due to lateral flow. When differential settlement places excessive stress on the foundation, it can cause cracks in the foundation and ground fissures beneath the floor, increasing the risk to the building structure. The settlement correction work provided by Geotech resolves this issue by utilizing the weight of the building as jack reaction force and employing a steel pipe pile driving method that directly presses high-strength steel pipe piles into stable supporting ground. The foundation on the settlement side is carefully lifted with hydraulic jacks and accurately corrected to a horizontal state. Additionally, high-resin repair materials are injected into the cracks of the foundation, and lightweight, self-hardening air milk is filled without gaps into the voids created underground by the settlement. Construction can be carried out while residents are living in the home, eliminating the need for relocation, and foundation reinforcement is achieved in a safe and secure environment with significantly reduced noise and vibration. We provide optimal construction plans tailored to the customer's needs.

The sinking and cracking of strip foundations caused by the aging of residential buildings and localized ground softening lead to issues that result in stress in daily life and a decrease in the asset value of the property. Large-scale demolition and reconstruction or house-moving work require high costs and temporary housing, but with Geotech's steel pipe pile driving method, it can be safely and reasonably corrected while living in your familiar home. This method utilizes the building's own weight as a reaction force to steadily drive steel pipe piles down to a stable support layer using a small hydraulic jack, accurately jacking up and correcting the sinking areas. Since it can be constructed with partial excavation, the construction period can be minimized, optimizing construction costs. Additionally, high-viscosity resin injection is applied to the cracks in the damaged strip foundation, and lightweight, durable air milk is filled and injected into the voids created by sinking under the floor and underground to restore ground bearing capacity. It generates minimal vibration and noise for neighbors and is the definitive method for correcting residential sinking with excellent cost performance. We will continue to support your important home with a reliable construction system.

Based on ground investigation data, it accurately combines the use of existing columns, steel pipe jacking methods, and pressure slab methods to detail the process of returning the entire building to a level position without distortion. It includes a checklist of management considerations unique to occupied sites, such as attention to noise reduction, selection of low-noise and low-vibration equipment, and dust prevention measures. This practical document is essential for builders to restore trust and address warranty issues, covering everything from dialogue techniques to alleviate the psychological stress of owners, to various procedural steps for reattaching ground guarantees and insurance application processes.

Localized subsidence and cracking occurring in the foundation of residential buildings are significant structural issues caused by uneven ground subsidence and localized softening. If left unaddressed, the tilt of the building will further increase, leading to a substantial decrease in asset value and reduced seismic resistance. The subsidence correction work provided by Geotech utilizes the building's own weight as jack reaction force and employs a steel pipe pile pressing method, where high-strength steel pipe piles are driven deep into a hard support layer. Piles are precisely anchored at the locations of localized subsidence, and accurate leveling is restored through precise jacking. Additionally, epoxy resin injection is applied to the cracks in the foundation concrete to restore structural strength, and high-density filling of air bubble mortar is used to raise the ground bearing capacity in areas of subsidence and underground voids. Construction can be carried out while residents are living in the home, minimizing noise and vibration, and compressing the construction period and costs to a minimum. We will permanently protect the structural safety and asset value of your important home.

Local subsidence and cracks in the foundation caused by seismic shaking and consolidation changes in weak ground lead to significant tilting and a dramatic decrease in the seismic resistance of homes. The subsidence correction work carried out by Geotech resolves these issues using a steel pipe pile driving method, where steel pipe piles are driven into a hard support layer under the weight of the building, monitored in real-time to the millimeter with the latest laser measurement systems. Hydraulic jacks are linked to precisely lift the building without adding stress, correcting it to its original level at the time of construction. At the same time, high-adhesion epoxy resin is injected into the cracks of the damaged foundation to fully restore structural strength and waterproofing performance, while high-strength bubble mortar (air milk) is densely injected to fill the cracks and voids that have formed in the subfloor due to subsidence. The work can be done while residents are living in the home, with no need to move to temporary housing, and is completed in a short period with minimal noise and vibration. This simultaneously improves the building's seismic performance and ensures lasting structural stability.

This is a cutting-edge engineering document that focuses particularly on technical management and safety within the house-jacking construction plan aimed at maintaining the residents' living conditions. It encompasses a special "pipe-following" construction process that safely corrects differential settlement while residents continue to live in the house, without ever interrupting essential lifelines such as city gas, water supply and drainage, electricity, and internet during the construction period. By controlling multiple hydraulic jacks with a computer and monitoring the building's behavior in real-time using a three-dimensional laser level measuring device, the lifting is performed with millimeter precision, preventing undue deformation stress on the structure. The on-site material storage area is optimized for space, and by adopting low-noise and low-vibration systems such as electric hydraulic pumps and soundproof generators, it perfectly prevents neighborhood troubles during construction in densely populated areas. This technical specification document promises the highest safety quality, explaining methods to reinforce foundation concrete cracks with carbon fiber sheets that possess ten times the strength of steel plates.

Local subsidence and cracks in the foundation of detached houses that occur after handover are very serious issues for contractors and house manufacturers in terms of customer response and after-sales support. Delays in identifying the cause and inadequate construction responses can lead to secondary complaints and a loss of brand trust for the company. GeoTech's subsidence correction work involves a steel pipe pile pressing method, where small hydraulic jacks use the weight of the building as a reaction force to drive steel pipe piles into deep supporting layers, precisely lifting the problematic foundation and restoring it to a high level of accuracy. Epoxy resin injection is applied to damaged concrete cracks to fully restore structural strength, and lightweight bubble mortar (air milk) is filled into ground cracks and voids to enhance ground contact. The work can be carried out while the residents remain in the house, significantly reducing the burden on homeowners with a short construction period and low vibration. With a reliable construction plan linked to the re-issuance of after-sales guarantees, we quickly resolve issues with homeowners and provide a deep sense of security.

The presence of buried waste and rubble, as well as irregular old embankment layers, which cannot be identified solely from the data of the ground survey conducted in advance, can be significant causes of localized settlement and diagonal cracks in the footing foundation. Such geological factors leading to uneven settlement cannot be prevented by simple surface ground improvement. Geotech's settlement correction work accurately identifies the causes based on excavation verification at the site and applies a steel pipe pile driving method that utilizes the building's own weight as a reaction force. Small-diameter steel pipes are pushed in with hydraulic jacks, penetrating the surface obstruction layers to firmly reach the hard supporting ground below. The irregularly settled footing foundation is safely jacked up and accurately returned to a level position, while cracked concrete foundations are repaired by injecting high-adhesion epoxy resin. Voids created by settlement under the floor and gaps around buried objects are filled with high-density air-entrained mortar to improve bearing capacity from the bottom up. The work can be completed in a short period while the residents remain in the building, fundamentally resolving the issues of irregular settlement.

Localized subsidence and cracking in residential shallow foundations can not only cause tilting of the building but also place excessive strain on the plumbing and equipment under the floor, potentially leading to damage incidents. Typical subsidence repairs often involve temporary suspension of utilities and moving to temporary housing, which can impose a significant burden on homeowners. GeoTech's subsidence repair work offers a groundbreaking jack-up plan that can be executed without interrupting essential services such as city gas, water supply, and electricity. While installing flexible joints to prevent pipe breakage and taking careful protective measures, we press and install steel pipe piles into deep hard layers using the weight of the building as a counterforce. We precisely lift the subsided shallow foundation to restore it to a level position within millimeters. At the same time, we inject epoxy resin into the cracks in the foundation concrete to restore strength and waterproofing, and we fill the voids in the subsided ground under the floor with high-density air-entrained mortar (air milk). This allows for construction while living normally, minimizing both the construction period and costs.

This construction method is a groundbreaking settlement correction solution for single-family homes that have experienced partial sinking of the foundation or structural cracks. It scientifically identifies the causes based on SWS (Screw Weight Penetration) tests and precise building level measurements, followed by partial jacking and ground reinforcement. For localized tilting caused by weak ground or uneven consolidation of fill, we use small hydraulic jacks and high-precision laser measurement devices to safely and reliably restore the level to within millimeters. Cracked areas of the foundation are repaired with epoxy resin injection and U-cut seals, and, if necessary, we optimally combine steel pipe pile driving methods and pressure slab methods to fundamentally eliminate the risk of future settlement. Our method fully accommodates construction while residents are living in the home, without the need for moving or temporary housing, allowing work to proceed while maintaining the residents' daily routines. We significantly reduce the financial and mental burden on homeowners, ensuring structural integrity and enhancing long-term asset value, so you can rest assured.

This is a reliable sinking correction solution that fundamentally addresses the issue of building subsidence accompanied by foundation cracks. For structural cracks in the foundation caused by uneven ground or localized softening, high-viscosity epoxy resin is injected and filled under high pressure and density to restore the compromised structural strength and significantly improve waterproofing. At the same time, a pressure plate is precisely installed directly beneath the sunken foundation, and high-precision millimeter-level lift-up is performed using hydraulic jacks to restore the tilted building to a precise horizontal state. After the jacking is completed, air bubble mortar (air milk) is poured into the fine gaps that have formed between the foundation and the ground, filling and solidifying them without any gaps, significantly increasing the contact area to prevent future re-sinking or differential settlement. Since this solution accommodates construction while residents are living in the home without the need for large machinery, extensive demolition, or temporary relocation, it greatly reduces the burden on homeowners' daily lives and secondary costs such as temporary housing rent. With reliable construction techniques and uncompromising quality control, we dramatically restore the seismic resistance, durability, and asset value of homes, providing long-lasting peace of mind.

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 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.

This is a state-of-the-art settlement correction solution that resolves building settlement issues accompanied by foundation cracks with millimeter-level precision, based on visualization data management using a 3D laser measurement system. For the foundation structure that has fractured due to settlement stress, high-viscosity epoxy resin is pressure-injected to create a dense seal, restoring the integrity and waterproofing of the structure and providing seismic strength greater than that of a new building. In the lifting process, a pressure plate and hydraulic jacks are placed directly under the foundation, and ultra-high precision laser level measuring instruments and displacement sensors are linked to continuously monitor and digitally measure the building's lifting behavior and tilt angle. To accurately restore horizontal alignment with millimeter precision without causing harmful distortions or stress concentrations in the structure, it perfectly prevents secondary damage to the house, such as wall coverings tearing or beams warping. After correction, self-hardening lightweight bubble mortar (air milk) is injected at high density into the voids beneath the foundation to distribute the ground pressure evenly, completely eliminating the risk of re-settlement. We offer consistent support for construction while residents are living in the property, with a reliable ground guarantee provided.

This is a stress-free subsidence correction plan that safely resolves building subsidence issues accompanied by foundation cracks without completely shutting off essential living infrastructure such as city gas, water supply and drainage, and electricity. For the foundation structure damaged by subsidence stress, high-viscosity epoxy resin is pressure-injected to tightly seal the cracks, restoring structural strength and waterproofing to the level of a new building. In the lifting process, flexible joint temporary installations and piping-following technology are introduced to prevent breakage of existing pipes, and high-precision laser measurements are used to accurately level the foundation in millimeter increments with a pressure plate and hydraulic jacks. During construction, the kitchen, bath, and toilet can be used as usual, so there is no need to move to temporary housing or incur unnecessary secondary expenses. After jacking up, lightweight aerated mortar (air milk) is injected at high density under the foundation to prevent re-subsidence, and by providing consistent support until a reliable ground guarantee is reinstated, we ensure the comfort of the client's living environment and the structural stability of their home.

This is a seismic and structural reinforcement type settlement correction solution that is implemented prior to large-scale renovations or remodeling work, fundamentally addressing foundation cracks and building subsidence. For foundation cracks caused by uneven ground settlement or deterioration, high-viscosity epoxy resin is pressure-injected to integrate and reinforce the structure, upgrading seismic strength and waterproofing to levels exceeding those of new constructions. In the lifting process, high-strength pressure plates and hydraulic jacks installed directly beneath the foundation are used, with constant monitoring via high-precision laser levels to accurately lift and correct the tilt in millimeter increments. By neatly resolving floor inclinations and column twists, the interior and fixture work during the renovation can proceed with exceptional precision and smoothness. After jack correction, high-density air-mortar is injected into the voids beneath the foundation to solidify and eliminate the risk of re-subsidence. We provide total support until the reattachment of ground guarantees, significantly enhancing the durability and asset value of the home after renovation.
