Settlement correction work | Identification of localized settlement due to buried debris! Load-bearing slab jacking method

Settlement correction work | Identification of localized settlement due to buried debris! Load-bearing slab jacking method

Identify localized subsidence caused by buried waste lurking in the gaps of survey points! Ensure precise horizontal restoration with pinpoint underground exploration and pressure plate jacking.

The debris and buried garbage hidden in the gaps of ground investigation data can cause irregularities in the ground, leading to significant localized subsidence where only parts of a building settle after construction or over time. Even if no abnormalities are detected in the preliminary investigation data, localized softening can result in dangerous distortions or structural cracks in the foundation and exterior walls. At Geotech, we conduct pinpoint underground exploration and situation identification through hand auger drilling to accurately clarify the causes of subsidence and the extent of abnormalities. In the repair process, we apply a pressure plate jack-up method using compact thick steel plates, allowing for precise millimeter-level horizontal lift-ups with small hydraulic jacks, even in confined spaces, using the building's weight as a counterforce. Furthermore, we fill any voids or cracks that occur after lifting with highly fluid air bubble mortar (air milk) and combine this with high-viscosity epoxy resin injection into the uneven foundation structure, achieving improved foundation strength and preventing re-subsidence. With Geotech's extensive subsidence correction construction menu, we provide structural repairs that ensure peace of mind while living in the building.

Ground reinforcement work | Achieving shortened construction time with zero curing and no soil displacement using the RES-P method.

Ground reinforcement work | Achieving shortened construction time with zero curing and no soil displacement using the RES-P method.

Significantly shorten construction time with zero waste! The RES-P method reduces total construction costs through a no-dirt-disposal approach and the combined effect of small-diameter steel pipes.

To ensure the long-term structural safety of buildings, appropriate ground reinforcement work based on ground surveys is essential. If the allowable stress of the ground is insufficient, uneven settlement can occur due to the building's load, leading to serious issues such as tilting or damage to the structure. The RES-P method, a piled raft foundation construction technique, efficiently addresses these problems. This method involves continuously driving small-diameter steel pipes (with an outer diameter of 48.6 mm) into soft ground, significantly enhancing the load-bearing capacity beneath the foundation through the combined action of the ground and the pipes. Since it does not use cement-based solidifying agents, there is zero residual soil generated on-site, which greatly reduces industrial waste disposal costs and transportation expenses. Furthermore, because there is no curing period required for the solidifying agent, work on the next phase of foundation construction can begin immediately after the pipe installation is completed, allowing for a reduction in the overall construction timeline. The use of lightweight 2-ton compact machinery minimizes noise and vibration, keeping the site environment clean. GeoTech Co., Ltd. offers reinforcement work that ensures reliable quality and cost optimization under precise management using construction management devices.

Ground reinforcement work | RES-P method that thoroughly considers neighbors with low noise and no soil disposal.

Ground reinforcement work | RES-P method that thoroughly considers neighbors with low noise and no soil disposal.

Thorough consideration for neighbors with low noise and no soil displacement! The RES-P method allows for clean construction without the use of cement, making it possible to work in densely populated areas.

To maintain the long-term safety of residences and buildings, appropriate ground reinforcement work is necessary. If construction is carried out on land with insufficient ground bearing capacity without taking measures, differential settlement will occur due to the weight of the building, leading to serious issues such as structural tilting and exterior wall cracks. The RES-P method smartly addresses these challenges with consideration for neighboring properties. This method involves driving slender steel pipes into soft ground, enhancing the supporting capacity beneath the foundation through the composite action of the ground and the pipes, and is a piled raft foundation technology. Its most notable feature is that it does not use cement solidifiers, resulting in no dust dispersion, mud stains, or construction waste. The vibrations and noise during work are extremely low, allowing for smooth construction without affecting the surrounding area, even in densely populated residential areas or narrow urban sites. Additionally, a lightweight small construction machine based on a 2-ton truck is used, enabling a clean transition to subsequent processes while maintaining the site’s leveling condition. GeoTech Co., Ltd. provides clean and reliable reinforcement work through the digitization of construction data and thorough quality management.

Ground reinforcement work | SMD method that reduces site costs with no soil disposal and low noise.

Ground reinforcement work | SMD method that reduces site costs with no soil disposal and low noise.

An environmentally friendly SMD method that achieves both the reduction of surplus soil disposal costs and the protection of the surrounding environment through construction without any generated soil and low-noise rotary penetration.

Ground reinforcement work is an essential construction process to prevent differential settlement and structural damage in soft ground, ensuring long-term durability. The SMD pile method developed by Geotech Co., Ltd. is a small-diameter rotary driven steel pipe pile method that achieves a high level of environmental consideration and cost reduction. The most significant feature of this method is its completely non-discharge construction through self-advancing rotary penetration. Since no construction-generated soil that becomes industrial waste is produced on-site, the disposal costs for surplus soil and the transportation costs for large vehicles from the site can be significantly reduced. The absence of cement milk eliminates the risk of cement scattering and groundwater contamination, and the work can be carried out with low noise and low vibration, greatly reducing noise complaints from neighboring residences. Furthermore, the use of compact construction machinery allows for smooth transportation and pouring even in narrow sites and densely populated residential areas. Under a nationwide construction network and a strict quality control system, we achieve high-quality ground reinforcement at low cost while reducing environmental impact.

Ground reinforcement work is an essential process to eliminate the risk of settlement that buildings face and to ensure long-term safety from a structural foundation perspective. In particular, insufficient ground measures in mid-rise steel and reinforced concrete structures, as well as large constructions that require high ground bearing capacity, can lead to distortion of the structure and serious defects. The SMD pile method provided by Geotech Co., Ltd. is a small-diameter rotary penetration steel pipe pile method certified by the Minister of Land, Infrastructure, Transport and Tourism, featuring special outer and inner wings attached to the open-type steel pipe tip. During rotary penetration, the inner wings appropriately capture soil to suppress core deviation during excavation, and when the target depth is reached, the soil inside the pipe completely blocks it, demonstrating tremendous end bearing capacity. This excellent support performance allows for a reduction in the number of piles and a decrease in the shaft diameter compared to conventional precast concrete piles and large-diameter piles, significantly optimizing the overall layout plan of foundation work. Our company has established a consistent system from prior foundation design support to on-site construction and torque data management, proposing ground reinforcement that ensures structural safety and achieves substantial cost reductions.

Ground reinforcement work | SMD method that completely prevents the settlement risk of cohesive soil layers with a sealing effect.

Ground reinforcement work | SMD method that completely prevents the settlement risk of cohesive soil layers with a sealing effect.

The Minister-approved SMD method prevents differential settlement accidents in weak, viscous soil using an open-type steel pipe and a special inner and outer wing for pipe internal blockage effects.

Ground reinforcement work is a foundational technology designed to prevent uneven settlement of buildings on weak ground and clay layers, ensuring structural safety over an extended period. Particularly when constructing buildings on thick clay layers containing moisture, neglecting appropriate reinforcement in advance can lead to distortions and defects in the structure due to consolidation settlement. The SMD pile method provided by Geotech Co., Ltd. is a Minister of Land, Infrastructure, Transport and Tourism certified rotary driven steel pipe pile method, equipped with special outer and inner wings at the tip of an open-type small-diameter steel pipe. During the rotary driving process, the inner wings capture soil into the pipe to prevent axial deviation, and upon completion of driving to the target depth, the captured soil completely seals off, creating a strong end bearing capacity. This ensures reliable support performance even on clayey ground (equivalent N value of 27 or lower), eliminating settlement risks from the structural foundation. Our company conducts detailed pre-analysis of soil data and automatic tracking using real-time torque management on-site, achieving high-quality ground reinforcement that objectively proves reliable bottoming through data.
