Settlement correction work | Foundation settlement cracks addressed with SWS investigation and partial jacking with consideration for neighbors.

Analyzing partial subsidence and cracks in the foundation using SWS investigation! We will ensure safe construction with consideration for neighbors in densely populated residential areas through low-noise and low-vibration partial jack adjustments.

This construction method is a surrounding consideration type of settlement correction solution that safely resolves partial sinking of strip foundations and structural cracks that occur in densely populated residential areas or small lots with narrow spacing from neighboring properties. By conducting a pre-emptive SWS (Screw Weight Insertion) test and precise level measurements, we accurately quantify ground unevenness even in tight spaces and identify the causes. During construction, we selectively use electric hydraulic pumps that do not emit exhaust gases, as well as low-noise and low-vibration equipment, while minimizing the storage space for materials to thoroughly reduce traffic obstruction and noise stress for neighbors. We place small multi-stage hydraulic jacks in the limited gaps under the floor and beside the foundation, performing millimeter-level horizontal restoration while monitoring with high-precision laser level measuring instruments. Cracked areas of the foundation are treated with epoxy resin injection, and we strongly prevent re-sinking through the insertion of small-diameter steel pipe piles and the installation of pressure-resistant slabs. This reliable method perfectly balances construction while the client resides in the property and consideration for the neighbors.

Settlement correction work | Recovering value of foundation settlement cracks through SWS investigation and partial jacking.

Scientifically elucidating partial subsidence and cracks in the foundation through SWS investigation! Dramatically restoring the asset value of real estate with partial jack adjustments and re-attaching ground guarantees.

This construction method is a settlement correction solution that addresses partial sinking and structural cracks in cloth foundations, which are issues that arise during the buying and renovating of used single-family homes, significantly enhancing real estate value. Through preliminary SWS (Screw Weight Penetration) tests and high-precision laser surveying, the causes of building tilt and uneven ground settlement are clarified with objective data. During construction, small hydraulic jacks are placed at the sinking areas, and the structure is accurately lifted to a level position in millimeter increments under constant laser level monitoring. Cracked cloth foundations are repaired with epoxy resin injection to restore structural strength, and measures such as the insertion of steel pipe piles into deep support layers and the installation of pressure plates are taken to prevent re-settlement. This process enables the passing of mortgage examinations and building inspections, providing total support up to the re-attachment of ground guarantees. It fundamentally proves the safety of "problematic tilted properties," leading real estate transactions and asset preservation to assured success.

Settlement correction work | Digital measurement for foundation cracks and settlement correction epoxy pressure plate

Prevent distortion of buildings with 3D laser measurement! Correct foundation cracks and subsidence with millimeter precision using high-adhesion epoxy resin injection and pressure-resistant slab methods.

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.

Sinking correction work | Epoxy pressure-resistant slab to repair foundation cracks and sinking without stopping the piping.

We will not stop city gas or water supply at all! We protect living infrastructure and repair foundation cracks and subsidence with high-adhesion epoxy resin injection and pressure-resistant slab methods.

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.

Foundation repair work | Correcting floor tilt to alleviate dizziness! Ground reinforcement work while living in the house.

Eliminate dizziness caused by the tilt of the floor! Completely restore the health and safety of your home with precise leveling measurements and a low-noise hydraulic jack method that allows for repairs while living in the space.

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.

Subsidance correction work | Floor tilt restoration and low-noise ground reinforcement for used housing sales assessment

Fundamental solutions for floor slope issues and dizziness problems pointed out in inspections! Enhancing the asset value and livability of existing homes with low-noise hydraulic jack methods.

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.

Subsidance correction work | Completely resolving floor tilt with low-noise ground reinforcement while living in the space.

No need for temporary housing! While living in the space, we will make millimeter adjustments to the floor's tilt using a low-noise hydraulic jack, achieving both the resolution of dizziness issues and a comfortable living environment through ground reinforcement.

This brochure explains the sinking correction work that resolves dizziness and health issues by correcting floor tilts without moving or temporarily relocating, allowing residents to continue their daily lives as usual. Millimeter-level floor inclinations that occur in homes continuously stress the human vestibular system, leading to unexplained dizziness and autonomic nervous system disorders. Our company conducts a preliminary Swedish-style sounding (SWS) survey and precise level measurements to objectively visualize the depth of ground weakness and the mechanisms of differential settlement. The construction procedure involves evenly placing compact hydraulic jacks directly under the foundation and safely lifting and correcting the building while implementing measures to follow the piping. We use low-noise, low-vibration quiet equipment for the work, allowing us to proceed quietly without causing noise issues, even in narrow sites close to property boundaries. After lifting, we combine steel pipe pile driving, i-LIFT, and the stubborn old man method to effectively prevent future re-settlement, thereby restoring a safe and healthy living environment.

Settlement correction work | Clarifying local settlement caused by underground buried waste! Pressure plate jack reinforcement

Objectively clarifying local subsidence caused by buried debris hidden in gaps of ground data! Restoring structural safety through pinpoint underground exploration and pressure plate jacking.

Underground debris and buried waste that cannot be captured at representative points during ground surveys can cause irregular localized subsidence over time, significantly impacting the structural safety of buildings, regardless of whether they are new or old. When underground obstacles hidden between standard SWS tests are the cause, rapid subsidence or structural cracks occur in specific areas rather than the entire building tilting, necessitating an investigation based on scientific data rather than intuitive repairs. Geotech visualizes the location and extent of obstacles through hand auger drilling and pinpoint underground exploration, and conducts numerical analysis of distortions in the exterior and interior using high-precision laser level measurements down to the millimeter. For subsidence correction, we employ a jack-up method with pressure plates that can be implemented in narrow spaces, synchronously driving small hydraulic jacks using the building's own weight as a reaction force, allowing for precise leveling without burdening the structure. Additionally, we combine high-density filling of air bubble mortar (air milk) into underground voids with high-adhesion epoxy resin injection into foundation cracks to prevent re-subsidence and establish the overall seismic and structural safety of the building. Geotech's comprehensive subsidence correction service menu supports a safe living environment.

Settlement correction work | Pinpoint identification of buried debris settlement due to survey omissions! Pressure-resistant slab construction.

Solve the subsidence of buried waste lurking in the gaps of survey points at low cost! Significantly reduce costs and construction time with pinpoint underground exploration and pressure plate jacking.

Underground debris and buried waste that cannot be fully anticipated during ground surveys can cause irregular localized subsidence, where only part of a building sinks. Implementing comprehensive piling or large-scale ground improvement can incur significant construction costs, so a rational corrective method that precisely identifies and addresses the buried areas causing the subsidence is extremely effective. Geotech locally identifies the subsidence areas caused by buried waste through hand auger drilling and pinpoint subsurface exploration, thoroughly cutting unnecessary preliminary survey costs and overall construction expenses. For horizontal adjustment, we apply a pressure plate jack-up method using compact thick steel plates. Even in narrow sites where the transport of temporary machinery is difficult, we perform precise lifting in millimeter increments using small hydraulic jacks, leveraging the building's own weight as a reaction force, dramatically reducing construction time and costs. After lifting, we flow air-entrained mortar (air milk) into the voids under the floor and use high-viscosity epoxy resin injection for any cracks in the foundation. Geotech's subsidence correction construction menu provides reliable and low-cost restoration of the foundation.

Settlement correction work | Identifying buried debris causing settlement in survey gaps! Jacking up the pressure plate.

Identify localized subsidence of buried waste lurking in the gaps of survey points! Quickly resolve initial issues with pinpoint underground exploration and pressure plate jacking.

Buried waste such as debris and construction waste hidden in the gaps of ground survey data poses a significant risk factor for unexpected localized subsidence after the handover of a house or in the early stages of a new construction. Since these issues cannot be fully captured by representative points in preliminary surveys, cases often arise where rapid inclinations or structural cracks occur in parts of the mat foundation, leading to disputes with homeowners. At Geotech, we conduct hand auger drilling and pinpoint subsurface exploration to accurately visualize the extent of buried waste and the causes of subsidence as objective numerical data. In the repair process, we apply a space-saving jack-up method for pressure plates, synchronously driving small hydraulic jacks using the building's own weight as a reaction force, and performing precise horizontal adjustments in millimeter increments under constant high-precision laser monitoring. After the lift-up is completed, we inject high-flow air bubble mortar into the voids created under the floor to equalize the ground pressure across the surface, while also pressurizing and sealing high-adhesion epoxy resin into the damaged mat foundation structure to restore its structural strength. Geotech's subsidence correction construction menu strongly supports builders in their after-sales service.

Presentation of Useful Materials for Subsidence Correction Work: Explanation of the Underpinning Method

Not only correct the sinking of the building, but also prevent further sinking! Construction can be carried out while occupied.

The "underpinning method" is commonly used in settlement repair work, where the load of the building is supported by steel pipe piles driven into the foundation using jacks, allowing for the entire building to be corrected. It prevents re-settlement and allows for construction to be carried out while residents remain in the building, without the need to move out. There is minimal noise, vibration, and dust generation, and the space required for equipment storage is also minimized. 【Features】 ■ The load of the building is supported by steel pipe piles driven into the foundation using jacks, correcting the entire building. ■ Construction can be carried out while residents remain in the building, without the need to move out. ■ Minimal noise, vibration, and dust generation. ■ Space-efficient equipment storage. *For more details, please refer to the PDF materials or feel free to contact us.

Settlement correction work

Establishing a reliable support structure and preventing further settlement, specialized settlement correction methods.

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.

Settlement correction work | Fundamental repair of settlement at retaining walls and uneven ground with steel pipe piles!

Eliminate the settlement of strip foundations occurring at the backfill of retaining walls and the boundaries of cut and fill! A high-durability settlement correction technology that fixes to a hard support layer by driving steel pipe piles under the weight of the building.

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.

Settlement correction work | Epoxy pressure-resistant slab to fix foundation cracks and settlement before renovation.

Fundamentally solve foundation cracks and partial subsidence before renovation! We dramatically enhance the seismic resistance of your home with high-adhesion epoxy resin injection and pressure-resistant slab methods.

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.

Subsurface Improvement Work | Blocking Liquefaction Risk of Existing Homes with Liquid Pressure Injection in Limited Spaces

Prevent liquefaction settlement risks in narrow and densely populated areas with chemical grouting injection! Safely restore existing homes to a level position using the i-LIFT method and digital measurement.

GeoTech offers a pre-subsidence prevention and subsidence correction solution using the "i-LIFT method," which employs liquid pressure injection technology for existing homes located in narrow sites or densely populated residential areas where large machinery cannot be brought in. This method utilizes specialized equipment that is ultra-compact and easy to transport, allowing for the precise injection of quick-setting cement-based grout into the soft sandy layers directly beneath the building. This technology gradually achieves the formation of a support layer, foundation reinforcement, and millimeter-level lift-up. By utilizing high-precision digital 3D displacement sensors and laser levels, we continuously visualize and monitor the behavior of the building in real-time during construction, ensuring that the correction is made to a perfect horizontal state without placing excessive stress on adjacent houses or structures. The method eliminates the need for large-scale demolition or excavation, allowing homeowners to remain in their familiar residences while construction is completed, accommodating "construction while living." With a focus on low noise, low vibration, and space-saving construction practices, we enhance the seismic resistance and structural safety of homes while preventing neighborhood disputes.

Subsidence correction work | Correcting the tilt causing dizziness through floor tilt analysis and i-LIFT.

Scientifically analyzing floor inclinations that induce unexplained dizziness! Restoring the levelness of buildings while living in them through exterior level measurements and the i-LIFT method.

Unexplained symptoms such as dizziness, headaches, and nausea are caused by slight tilting of the floor due to uneven settling of the residence, which puts constant stress on the sense of balance. At Geotech, we focus on the correlation between structural mechanics and biological sensations, providing scientifically-based settlement correction solutions. First, we conduct external level measurements of buildings using advanced auto levels and laser equipment, analyzing and visualizing the maximum amount of settlement and deformation angles (such as V-shaped and U-shaped) down to the millimeter. Additionally, we combine ground investigations such as SWS tests to identify the mechanisms of settlement occurrence. In the correction process, we apply "settlement correction while living in the space," which does not require temporary housing or moving, allowing us to carry out the work without disrupting daily life infrastructure. Our main method, the "i-LIFT method," involves three stages of grout pressure injection deep into the ground, achieving both support plate formation and precise lift-up simultaneously. By combining this with the foundation reinforcement technique "Ganko Oyaji method," we permanently prevent re-settlement and restore a safe and secure living environment.

Subsidence correction work | Cure the cause of dizziness with floor tilt analysis and leveling of the home.

Scientifically analyze the floor slope that causes unexplained dizziness! Restore the building's levelness while living in it through exterior level measurements and the i-LIFT method.

Unexplained physical discomforts such as dizziness, headaches, and a feeling of floating are caused by the slight tilting of floors due to differential settlement of buildings, which continuously stresses the balance function. At Geotech, we focus on the correlation between structural mechanics and human ergonomic sensations, providing advanced numerical data-based settlement correction solutions. First, we conduct high-precision measurements of the building's perimeter levels, analyzing and visualizing the height differences and maximum settlement amounts around the building, as well as the deformation angles (whether it is uniform settlement or differential settlement) down to the millimeter. Additionally, we combine investigations such as SWS tests to understand ground behavior. In the correction process, we apply "settlement correction while living," which does not require moving or temporary housing, allowing us to carry out the work without disrupting the living environment. Our core technology, the "i-LIFT method," integrates support plate formation and precise lifting through multi-stage grout pressure injection into the deep ground. By combining it with the foundation reinforcement method "Ganko Oyaji," we physically shut out re-settlement and scientifically restore a comfortable and safe living space.

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.
