Subsidance correction work | Low-noise ground reinforcement work to correct floor tilt during renovation.

Subsidance correction work | Low-noise ground reinforcement work to correct floor tilt during renovation.

Unexplained dizziness and headaches: Could the tilt of the floor be the cause? Restore the levelness of your home and a healthy living environment with a low-noise hydraulic jack method during renovations.

This catalog explains a sinking correction method that addresses the often-overlooked floor tilt during renovations, fundamentally improving residents' dizziness and health issues. Subtle floor inclinations caused by uneven ground subsidence can chronically stress the semicircular canals, leading to autonomic nervous system disturbances and headaches. Our company objectively clarifies the causes of subsidence through precise level measurements around the building and Swedish sounding (SWS) surveys. During construction, we carefully lift the building while monitoring its displacement in millimeter increments in real-time, using small hydraulic jacks. By employing low-noise equipment that minimizes operational sounds and vibrations, we can restore the level state within a short period without requiring residents to leave their familiar homes or move to temporary accommodations. Furthermore, by combining steel pipe pile driving into deep supporting layers and filling voids under the foundation, we thoroughly prevent future subsidence. We propose technology that enhances the structural safety of homes and realizes a safe and healthy living environment.

Settlement correction work | Identifying buried debris causing settlement in investigation gaps! Pressure plate renovation approach

Settlement correction work | Identifying buried debris causing settlement in investigation gaps! Pressure plate renovation approach

Identify the subsidence of buried waste lurking in the gaps of the survey points! Revitalize the substructure before renovation with pinpoint underground exploration and pressure plate jacking.

When planning large-scale renovations or seismic reinforcement work, debris and buried waste hidden in the gaps of ground survey data can pose a hidden risk of uneven settlement, leading to floor re-tilting or fixture malfunctions after the completion of the construction. No matter how much the upper structure is renewed, if the foundation and the underlying ground's softening are left unaddressed, the building's inherent longevity cannot be achieved. At Geotech, we conduct hand auger drilling and pinpoint underground exploration as part of the ground and foundation diagnosis before starting renovations, visualizing the extent of buried waste and settlement factors as objective numerical data. In the leveling process, we apply a pressure plate jack-up method that does not require extensive demolition work, using small hydraulic jacks to achieve precise horizontal restoration in millimeter increments, leveraging the building's own weight as a reaction force. After lifting, we pressure-inject high-flow air bubble mortar (air milk) into the voids under the floor to equalize the ground pressure, and we encapsulate the damaged cloth foundation structure with high-adhesion epoxy resin to restore structural strength beyond that of new construction. Geotech's settlement correction work menu enhances the overall quality and durability of the renovation.

Ground reinforcement work | Reduce costs with the ETP method for shortened construction periods and easy removal!

Ground reinforcement work | Reduce costs with the ETP method for shortened construction periods and easy removal!

A next-generation ground reinforcement ETP method that achieves both shortened construction periods and cost reduction. It builds a solid foundation quickly with no soil disposal and no curing.

This document explains the importance of "ground reinforcement work" in achieving total cost reduction and shortening construction periods in construction projects, as well as the features of the "ETP method" that make this possible. In addressing soft ground, traditional methods faced challenges such as costs for disposing of excess soil and time losses due to curing periods. The ETP method is a soil displacement method that involves rotating and pressing a steel pipe equipped with a disc-shaped expansion wing and a drilling auxiliary bit into the ground. Since it does not use cement, there is no need for a curing period, allowing for immediate transition to the next process after pouring, and there are no costs for soil disposal. Additionally, during reconstruction, the piles can be easily removed and recovered by reversing the rotation, making it an economical and sustainable choice for future land use. With a combination of 16 sizes of pile diameters ranging from φ89.1mm to φ609.6mm and high-strength steel pipes, optimal designs without waste are possible. GeoTech Co., Ltd. significantly contributes to streamlining construction periods and costs while maintaining quality by managing construction data in real-time and ensuring prompt and accurate construction arrangements.

Ground reinforcement work | Strengthening structural seismic resistance with the ETP method, which is strong in both pushing and pulling!

Ground reinforcement work | Strengthening structural seismic resistance with the ETP method, which is strong in both pushing and pulling!

Strongly responds to pushing and pulling! ETP method enhances seismic resistance. The disc-shaped tip wings counteract loads from multiple directions, ensuring the safety of structures.

This document provides a detailed explanation of advanced technologies for "ground reinforcement work" and the "ETP method," which dramatically enhance the seismic resistance and safety of structures against multi-directional loads caused by earthquakes and strong winds. To prevent differential settlement and tipping accidents on soft ground, a reliable foundation structure that can withstand not only compressive loads but also tensile forces is essential. The ETP method is a rotary driven steel pipe pile method equipped with a disc-shaped enlarged wing and excavation auxiliary bit at its tip, which has received certification from the Minister of Land, Infrastructure, Transport and Tourism and has been publicly proven to have support performance in both compression and tension directions. The construction method, which does not use cement and generates no soil displacement, prevents soil contamination while achieving high penetration and strong resistance by compacting the surrounding ground. With a total of 16 sizes of pile diameter variations and the selection of high-strength 590N grade steel pipes, optimal designs without waste can be achieved even under complex stress conditions. GeoTech Co., Ltd. uses construction management equipment that automatically records rotational torque and penetration depth to accurately determine the reach of the support layer, providing reliable foundation work that is strong against earthquakes nationwide.

Ground reinforcement work | Constructing high-strength piles with the Pure Pile method that are unaffected by soil conditions.

Ground reinforcement work | Constructing high-strength piles with the Pure Pile method that are unaffected by soil conditions.

We propose the Pure Pile method, which forms pile-like reinforcement using high-strength cement milk without mixing with local soil, preventing any influence from soil conditions and avoiding differential settlement.

To ensure the structural safety of buildings over a long period, it is essential to accurately analyze the characteristics of the local ground and to carry out appropriate ground reinforcement work to prevent uneven settlement. The Pure Pile method proposed by Geotech Co., Ltd. is an innovative ground reinforcement technology that constructs pile-like reinforcement bodies by directly replacing the ground with high-strength cement milk while expanding the ground laterally using a conical excavation head. Because it uses a 100% cement milk structure without mixing with local soil, it is unaffected by soil quality in diverse ground conditions, including humus layers, and can consistently demonstrate the planned high strength and quality. By evenly distributing a large number of reinforcement bodies with a design pile diameter of 20 cm, it supports the building load in a balanced manner across the surface, achieving high vertical bearing capacity and effectively eliminating the risk of settlement accidents in structures. Additionally, due to the construction structure that generates almost no residual soil, it reduces the costs of transporting and disposing of leftover soil from the site. At Geotech, under an ISO-certified quality management system, specialized construction technicians thoroughly manage real-time data to provide reliable and trustworthy foundation reinforcement.

Ground improvement work | Achieving reduction of leftover soil and total cost reduction with the Pure Pile method.

Ground improvement work | Achieving reduction of leftover soil and total cost reduction with the Pure Pile method.

Significantly reduce disposal costs with a no-excavation structure that minimizes the generation of excess soil. Geotech proposes the Pure Pile method, which balances high load-bearing capacity and excellent economic efficiency.

To prevent building differential settlement accidents and ensure long-term structural stability, prior ground analysis and appropriate ground reinforcement work are essential. The Pure Pile Method proposed by Geotech Co., Ltd. is an environmentally friendly foundation reinforcement technology that directly constructs pure pile bodies underground using high-strength cement milk. This method employs a construction principle that expands the ground laterally while penetrating, and the use of straight rods that do not produce excavated soil dramatically reduces the amount of residual soil generated on-site. By minimizing the occurrence of residual soil removal work and disposal costs, significant total cost reductions are achieved. Additionally, since it does not mix with locally generated soil, it is unaffected by soil quality, ensuring high support performance even in humus-rich ground. By designing a balanced arrangement of numerous small-diameter reinforcement bodies with a design pile diameter of 20 cm, it disperses the building load and eliminates the risk of differential settlement in advance. Geotech provides safe and high-quality construction under a strict construction management system certified by ISO, recording on-site data in real time.

Submergence correction work | Strongly supporting the longevity of wooden houses with carbon fiber foundation regeneration method.

Submergence correction work | Strongly supporting the longevity of wooden houses with carbon fiber foundation regeneration method.

No need for demolition, perfect for renovation sites! Proposing a method for extending the lifespan of wooden houses and improving construction efficiency through carbon fiber foundation regeneration and subsidence correction work.

This catalog proposes the "Carbon Fiber Foundation Restoration Method" and ground subsidence correction solutions, which demonstrate significant effectiveness during large-scale renovations and seismic retrofitting of existing homes, aimed at contractors, house manufacturers, and renovation businesses. By closely applying carbon fiber sheets, which have ten times the tensile strength of steel, to the existing foundation structure while concurrently conducting seismic retrofitting of the superstructure, we can significantly restore and enhance the bending strength and shear resistance of the foundation without the need for demolition or additional construction. Additionally, for issues such as uneven subsidence of the ground or tilting of the house discovered during on-site surveys, we combine high-precision subsidence correction work using small hydraulic jacks and steel pipe pile driving to accurately level the structure to the millimeter and prevent re-subsidence. Our compact construction system, which does not require heavy machinery, allows for smooth completion even in narrow sites or occupied locations, minimizing the occurrence of additional construction periods and cost increases. With reliable technical evidence and ground warranty support, we strongly assist in gaining the trust of clients and improving order rates.

Subsurface correction work | Carbon fiber foundation regeneration method for earthquake-resistant and long-lasting homes

Subsurface correction work | Carbon fiber foundation regeneration method for earthquake-resistant and long-lasting homes

Protect your home from the shaking of massive earthquakes! Achieve long-lasting wooden houses and overwhelming seismic performance through the powerful combination of carbon fiber foundation regeneration methods and subsidence correction.

This catalog is a technical proposal introducing the "Carbon Fiber Foundation Rehabilitation Method" and ground subsidence correction solutions that respond to disaster prevention measures and seismic reinforcement needs for the massive earthquakes anticipated in the future, while simultaneously achieving the longevity of wooden houses and the strengthening of their foundational structures. By adhering and integrally molding carbon fiber sheets, which boast over ten times the tensile strength of steel, with high-adhesion epoxy resin to existing foundation concrete that has developed cracks due to aging and differential settlement, we dramatically enhance the shear resistance and toughness of the foundation without the need for demolition or additional pouring. Furthermore, for the tilting of houses caused by ground differential settlement, we apply high-precision jack-up construction using steel pipe piles and pressure plates, accurately leveling the structure to the millimeter and securely anchoring it to deep supporting layers. The objective effectiveness has been proven through full-scale strength tests conducted by public institutions, providing overwhelming reliability and assured structural safety for resolving foundation nonconformities identified in seismic assessments and enhancing disaster prevention functions during renovations.

Ground Investigation | A Smart Foundation Specification Explanation Method to Eliminate Excess Piles in Single-Story Logistics Warehouses

Ground Investigation | A Smart Foundation Specification Explanation Method to Eliminate Excess Piles in Single-Story Logistics Warehouses

Elimination of excessive piles in single-story logistics warehouses! By changing to direct foundations using shallow soil bearing capacity data from plate load tests, we smartly achieve cost reduction and the client's satisfaction.

In the construction plan for single-story logistics warehouses, the designation of expensive deep pile foundations or columnar improvements due to the underestimation of safety factors is a significant issue that severely pressures construction costs. This document explains a smart foundation explanation technique using "plate load tests" to measure the true bearing capacity of the shallow ground directly beneath the foundation and eliminate excessive ground reinforcement work. Geotech's plate load tests directly measure the ultimate bearing capacity and deformation coefficients at the actual pressure surface level, scientifically supporting design changes to direct foundations such as slab foundations. High-precision settlement simulations based on staged loading data prevent the risk of unevenness and settlement of the floor slab associated with forklift operations and the installation of high-rise racks. Furthermore, the eco-foundation proposal, which minimizes the generation of excavation spoil, also contributes to CO2 emission reduction. By presenting clear technical evidence, we fulfill the requirements for structural compatibility assessment and accountability to clients, strongly supporting significant cost reductions and shortened construction periods. We encourage you to utilize this document to achieve a highly satisfactory optimal foundation design.

Ground reinforcement work | Achieving reliable trust with public evaluation and performance certification through the RES-P method.

Ground reinforcement work | Achieving reliable trust with public evaluation and performance certification through the RES-P method.

Obtain public evaluation and performance certification! Ground reinforcement RES-P method that supports buildings for a long time based on clear design standards such as evaluations from the Japan Building Center.

To ensure the structural safety of newly constructed buildings over the long term, reliable ground reinforcement work is essential. Uneven settlement due to insufficient ground bearing capacity can cause cracks in exterior walls and tilting of the building, significantly reducing asset value. The RES-P method, a piled raft foundation construction method, provides extremely high structural reliability to address these issues. This method has obtained architectural technical performance certification from the General Incorporated Foundation Japan Building Disaster Prevention Association (GBRC Performance Certification No. 04-02) and evaluation from the Japan Building Center (BCJ-F872), allowing for reinforcement design based on clear calculation standards recognized by public institutions. By improving the bearing capacity beneath the foundation through the combined effects of slender steel pipes and the ground, it can be adapted to strip foundations and mat foundations without special foundation structural reinforcement. As it employs a non-dredging penetration method that does not use cement-based solidifying agents, it reduces the cost of disposing of excess soil while keeping the site environment clean. GeoTech Co., Ltd. offers absolute peace of mind to clients through thorough quality control and data assurance systems using construction management devices.
