Ground reinforcement work | High-support-capacity small-diameter steel pipe piles suitable for large-scale facilities to stores.
A small-diameter steel pipe pile method equipped with a rich variety of pile diameters. It achieves optimal foundation reinforcement tailored to design loads, from small residential buildings to large stores.
This proposal is a flexible ground reinforcement solution using small-diameter steel pipe piles that responds to the diverse building scales and design loads, ranging from single-family homes to large retail stores, medical and welfare facilities, logistics warehouses, and retaining walls. To ensure long-term safety while minimizing excessive design in construction planning, it is crucial to select a foundation reinforcement method that fits the site conditions and structural loads perfectly. The small-diameter steel pipe pile method enables extremely rational and efficient structural design tailored to the design ground bearing capacity, thanks to its rich lineup of shaft diameters and various enlarged tips. As it employs a completely non-displacement rotary insertion method that does not use cement, it generates no construction waste even at large sites requiring mass pouring, significantly reducing disposal costs and the labor involved in removal. The applicable geology is broad, including sandy soil, clay, and loam layers, ensuring safety through a clear bearing capacity calculation formula. GeoTech is equipped with a nationwide construction network and a data tracking system using digital management devices, providing highly reliable and top-quality foundation reinforcement for all types of construction projects.
basic information
This construction method is a rotary penetration pile method that uses general structural carbon steel pipes with an outer diameter ranging from φ89.1mm to φ216.3mm, along with multi-stage enlarged wing sizes. The applicable conditions are buildings with three stories or fewer, a height of 13m or less, a total floor area of 1,500 square meters or less, and retaining walls or structures with a height of 3.5m or less. The maximum construction depth can accommodate up to 130 times the shaft diameter (up to a maximum of 19.2m, etc.) and is suitable for various soil types. It has obtained public certifications such as GBRC performance certification, allowing for high-precision and objective allowable bearing capacity calculations based on SWS tests and penetration tests.

Applications/Examples of results
It is widely used for foundation reinforcement of small to medium to large-scale buildings such as detached houses, apartments, roadside stores, drugstores, medical and nursing facilities, childcare centers, and warehouses. It is ideal for sites that want flexible pile arrangements to match site conditions and structural shapes, as well as for development projects that aim to reduce disposal costs by minimizing the generation of drilling waste when driving numerous piles. Additionally, it is widely adopted in design projects where objective and clear calculation evidence is required for confirmation applications, as well as for standard foundation specifications by nationwide operators.
