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.

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.

When planning a building, it is essential to comply with regulations and accurately assess whether the ground can safely withstand the building's load, selecting appropriate ground reinforcement work. The Pure Pile method proposed by Geotech Co., Ltd. is a ground reinforcement technology for single-family homes that constructs straight piles underground using high-strength cement milk. Unlike traditional columnar improvement methods, it adopts a design specification that balances the placement of numerous small-diameter reinforcement bodies with a design pile diameter of 20 cm, dramatically reducing the risk of uneven settlement by evenly distributing the building's overall load. Additionally, the direct replacement structure, which does not mix the local soil with cement, is unaffected by soil quality, allowing for stable acquisition of high strength and excellent vertical support even in humus-rich ground. The straight rod structure, which does not generate excavated soil, significantly reduces the amount of residual soil, enabling economical construction. Geotech ensures high reliability in construction quality through the presence of qualified dedicated engineers and real-time data management.

To eliminate the risk of differential settlement in buildings and establish long-term safety, it is essential to carry out ground reinforcement work based on reliable data and objective technical assessments. The Pure Pile method proposed by Geotech Co., Ltd. is a ground reinforcement technology that has obtained public performance certification, which constructs a reliable support foundation using high-strength cement milk. It adopts a 100% cement milk replacement structure that does not mix with local soil, ensuring uniform high pile strength as designed, even in soft ground such as humus layers, without being affected by soil quality. By designing a balanced arrangement of numerous small-diameter reinforcement bodies with a design pile diameter of 20 cm, it effectively distributes the building load over a surface, preventing settlement accidents before they occur. At Geotech, under an ISO-certified quality management system, specialized construction engineers use construction management devices on-site to automatically record and manage penetration depth and torque data in real-time. We deliver reliable construction quality based on clear objective evidence.

This proposal is a ground reinforcement solution using small-diameter steel pipe piles to ensure the long-term structural safety of buildings. To prevent uneven settlement and tilting of structures caused by insufficient ground bearing capacity, we will propose an optimal reinforcement plan based on thorough preliminary ground surveys. The small-diameter steel pipe pile method is a technique that involves rotating and driving a steel pipe equipped with a special enlarged base wing at its tip, and since it does not use cement solidifiers, it generates no construction waste, allowing for significant reductions in disposal costs. Additionally, the low-noise and low-vibration construction is gentle on the surrounding environment and soil, enabling smooth work completion even in densely populated urban areas or narrow sites. With a wide variety of pile diameters and clear support capacity calculation formulas, we achieve rational foundation design that accommodates a broad range of geological conditions. At Geotech, we adhere to ISO quality management systems, ensuring real-time monitoring on-site and comprehensive management of all processes by qualified personnel. With reliable technology and a rigorous inspection system, we firmly support the safety of our clients' valuable assets and buildings.

This proposal presents a small-diameter steel pipe pile method to address ground reinforcement challenges in densely populated urban areas and narrow sites where the distance to property boundaries and adjacent buildings is limited. Selecting the optimal reinforcement method is crucial to eliminate the risk of ground subsidence and ensure the safety of structures. The small-diameter steel pipe pile method utilizes specialized construction equipment that is compact and highly mobile, allowing for smooth transportation and construction even in restricted spaces where large machinery cannot enter. By adopting a rotary penetration method, it reduces noise and vibration during construction, significantly lessening the environmental impact on neighboring residents. Additionally, since it is a no-excavation and no-curing method that does not use solidifying agents like cement, it allows for immediate transition to the next phase of foundation work after completion of the installation, contributing to a reduction in the overall construction period. Its applicability ranges widely from small-scale buildings of three stories or less to retaining walls, and it enables highly accurate bearing capacity calculations based on SWS test data.
