[Technical Catalog] IPH Method (Internal Pressure Filling Joint Reinforcement)
Creating an environment that protects life and livelihood. Dissemination of reliable technology.
The IPH method (internal pressure filling joint reinforcement) replaces the air present inside the concrete with injected resin, allowing it to fill even the fine cracks at the ends by diffusing radially from the inside of the drilled holes. This method not only enhances the adhesion strength of reinforced concrete but also provides a high anti-corrosion effect, leading to improved durability. It has received technical evaluation from the Japan Society of Civil Engineers and has obtained a patent for the method. 【Catalog Contents】 ■ IPH Method ■ What is the IPH Method ■ Features ■ Construction Procedure ■ Performance Recovery Experiment of Column Specimens ■ Papers on the IPH Method ■ Various Case Studies *For more details, please refer to the technical catalog.
