Ground reinforcement work | The necessity of protecting buildings with public performance certification and advanced quality management systems.
Ground reinforcement work
The necessity of ground reinforcement work through obtaining public performance certification and strict quality control. Achieving high reliability in foundation quality through tracking records of all pouring data.
In ground reinforcement work, ensuring objective technical grounds and strict construction quality management is a fundamental and important element in securing the safety and reliability of structures. If poor construction occurs due to insufficient ground evaluation or management, it can lead to differential settlement, directly resulting in a loss of trust for the client and the designer. The Tiger Pile Method is a reliable ground reinforcement technology that has obtained GBR-C performance certification (No. 06-12 Rev. 4) from the General Incorporated Foundation Japan Architectural Comprehensive Testing Institute. A formula for allowable bearing capacity has been established based on numerous actual column loading test data, promising high-quality construction that thoroughly eliminates variations in strength through the composite effect of soil-cement columns and stepped steel pipes. GeoTech Co., Ltd. monitors and records rotational torque and penetration depth in real-time using dedicated equipment based on an ISO 9001 certified Quality Management System (QMS). We ensure traceability by electronically storing construction data and provide reliable foundation reinforcement work with a comprehensive warranty system.

basic information
The Tiger Pile method has objective specifications that have obtained the GBR Performance Certification (No. 06-12 Rev. 4) from the Japan Architectural Institute Foundation. The application conditions are for buildings with three stories or less above ground, a eaves height of 10 meters or less, a total floor area of 8,000 m² or less, and retaining walls with a height of 5 meters or less, with a design ground pressure of 300 kN/m² or less. The reinforcement consists of column diameters of φ400, 500, and 600 mm, as well as hot-formed stepped steel pipes (φ76.3 mm, φ114.3 mm), accommodating pipe lengths of 0.5 to 8.0 meters. It is a specification that proves quality through automatic recording by a construction management device.

Applications/Examples of results
It is ideal for various housing projects that require reliable design quality and construction certification, as well as for practical sites that need clear data submissions to approval agencies and defect insurance. It is particularly widely used in small-scale detached houses, three-story buildings, and retaining wall reinforcement designs, where objective calculations of allowable vertical bearing capacity based on public performance certification are emphasized. It is utilized in the practices of designers and contractors who wish to provide clients with peace of mind and solid construction evidence through ISO 9001-compliant construction management and electronic data recording.
