Ground improvement work | Achieving reduction of leftover soil and total cost reduction with the Pure Pile method.
Ground reinforcement work
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.
Inquire About This Product
basic information
This construction method is a technical specification for placing reinforcement bodies with a design pile diameter of 20 cm, capable of reaching a maximum construction depth of 10 meters from the ground surface. The applicable ground types are sandy soil, clayey soil, and humus soil. The applicable buildings are small-scale structures and floor slabs with three stories or fewer, a height of 13 meters or less, a eaves height of 9 meters or less, and a total floor area of 1,500 square meters or less. It has obtained the Architectural Technical Performance Certification from the Japan Building Disaster Prevention Association (GBRC Performance Certification No. 11-28). This technology is based on objective evidence that eliminates poor solidification by forming a pure cement milk column without mixing soil and cement, and reduces disposal costs for construction waste through a construction structure that does not involve soil removal.

Applications/Examples of results
It is suitable for ground reinforcement work and subsidence prevention measures in small-scale buildings such as detached houses, apartment buildings, and stores. It is particularly effective in urban areas or narrow sites where there is a desire to reduce the transportation of excavated soil and disposal costs. It is also suitable for foundation reinforcement applications in humus soil and clayey soil where mixing with locally generated soil needs to be avoided. It is used in situations where there is a need to review and reduce costs from conventional columnar improvement methods, as well as in subsidence prevention work for floor slabs in stores and factories. It is widely utilized in design and construction sites that aim to ensure reliable structural stability while reducing construction costs and environmental impact.
