Ground reinforcement work | Cleanly reinforce the ground by suppressing residual soil with the Pure Pile method.
Reduce site-generated residual soil with a straight rod that does not produce spoil. We propose a clean pure pile method that avoids the risk of hexavalent chromium leaching.
To prevent fatal differential settlement accidents in buildings and ensure long-term safety, reliable ground reinforcement work based on ground surveys is essential. The Pure Pile method proposed by Geotech Co., Ltd. is a clean ground reinforcement technology that replaces the ground with high-strength cement milk while laterally pressing and expanding the ground. By using straight rods that do not generate excavated soil, it minimizes the amount of construction waste and significantly reduces disposal costs and the number of large dump trucks required for transport. Furthermore, the structure does not mix with the local soil, eliminating the risk of leaching harmful substances such as hexavalent chromium, thereby enhancing safety for the surrounding environment and groundwater. By installing numerous reinforcement bodies with a design pile diameter of 20 cm to distribute and support the building load, it demonstrates strong vertical support capacity across a variety of soil types, from sandy soil to humus soil. At Geotech, we provide reliable ground reinforcement construction that combines environmental considerations and high quality, under ISO-certified quality management, with real-time monitoring conducted by certified engineers.
basic information
This construction method has a uniform specification with a design pile diameter of 20 cm and can accommodate a maximum construction depth of up to 10 m. The applicable ground types are sandy soil, clayey soil, and humus soil. The target structures include single-family homes with three stories or fewer, a height of 13 m or less, and a total floor area of 1,500 square meters or less, as well as ground slabs. It has obtained the Building Technical Performance Certification from the Japan Building Comprehensive Testing Institute (GBRC Performance Certification No. 11-28). By adopting a non-dredging type straight rod, it reduces the cost of soil disposal and guarantees a uniform strength with 100% cement milk, ensuring a safe specification.

Applications/Examples of results
It is suitable for preventing ground subsidence and reinforcing the bearing capacity of single-family homes, apartments, stores, etc., in densely populated residential areas and narrow urban sites. It is particularly effective in sites where there is a desire to reduce the transportation of construction waste and disposal costs associated with construction work. Additionally, it is ideal for foundation reinforcement work in environmentally conscious buildings that aim to minimize the risk of hexavalent chromium leaching, as well as in soft ground with thick humus layers. It is widely used in construction projects that aim to simultaneously meet environmental protection, economic efficiency, and high structural safety.
