Ground reinforcement work | The necessity of protecting buildings with public performance certification and advanced data management.
Ground reinforcement work
The necessity of ground reinforcement work through performance certification and data management by a third-party organization. Protecting the safety of buildings from uneven settlement based on objective evidence.
In ground reinforcement work, ensuring objective technical foundations and high reliability in construction quality management is extremely important for maintaining the structural safety of buildings and fulfilling social accountability. If ground improvement with insufficient scientific basis or opaque construction that leaves no records is carried out, there is a risk of damage compensation due to differential settlement accidents, which directly leads to a loss of trust for the operators. The Tiger Pile Method is a highly reliable ground reinforcement technology that has obtained the GBR-C performance certification (No. 06-12 Rev. 4) from the General Incorporated Foundation Japan Building Disaster Prevention Association. By using a load-bearing capacity calculation formula established from numerous load test data, it constructs a robust foundation that eliminates strength variations through a composite structure of soil-cement columns and stepped steel pipes. At Geotech Co., Ltd., we electronically record pouring data in real-time using construction management equipment under an ISO 9001 certified quality management system. We ensure complete traceability and comprehensive support for various guarantees, delivering overwhelming peace of mind to clients and confirmation application agencies.
Inquire About This Product
basic information
The Tiger Pile Method has public specifications that have obtained the GBR Performance Certification (No. 06-12 Rev. 4) from the Japan Building Disaster Prevention Association. The applicable targets are buildings with three stories or fewer, 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, corresponding to a design ground pressure of 300 kN/m² or less. It consists of column diameters of φ400, 500, and 600 mm, and stepped steel pipes (φ76.3 mm, φ114.3 mm) with excellent adhesion performance, and it is a specification that can objectively prove quality through automatic recording by construction management devices.

Applications/Examples of results
It is ideal for various housing projects where objective design quality and construction certification are strictly required, as well as for sites that need clear submission data for approval agencies and defect liability insurance. It is widely used in single-family homes and three-story buildings where accurate allowable bearing capacity calculations based on public performance certification are emphasized, as well as in foundation reinforcement design for retaining walls. Construction management in compliance with ISO 9001 and digital pouring records are utilized in practical settings by contractors and designers who want to provide reliable construction evidence to clients and project owners.
