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 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.

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.

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.

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.

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 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.

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.

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.

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.

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.
