中日建設株式会社／一般社団法人 IPH工法協会 Company Profile

The special website for the "IPH method," which achieves strength recovery and durability improvement of concrete structures, has been launched in collaboration with industry and academia. This site compiles information related to the restoration of civil engineering heritage using SGI Engineering's IPH method in collaboration with industry, government, and academia. Please take a look.

Due to the impact of the novel coronavirus, various restrictions have been imposed on our social lives, forcing us to live in discomfort. However, thanks to the generosity of Professor Mitsu Nakamura from Nagoya University, we will hold a "Workshop on Repairing Concrete Structures" via Zoom this year as well. Even during the pandemic, infrastructure repairs cannot be delayed, and we hope to provide you with valuable information, even if just a little. We kindly ask for your enthusiastic participation.

We would like to introduce examples of the nationwide adoption of the concrete repair and reinforcement method "IPH Method." ◆ Target: Repair work on Mochimizu Bridge on General Prefectural Road Kumamoto Hama Line [Kumamoto Prefecture] ◆ Contractor: Takano Development Co., Ltd. This year, repair work was carried out on the P1 pier and the girder section above P5 of Mochimizu Bridge (bridge length 51m), which is classified as category 3. The "IPH Method" was used as a concrete reinforcement measure against cracking. The "IPH Method" allows for filling down to fine details by replacing the air present inside the concrete with injected resin. For more details, please feel free to contact us. *You can freely check the actual method reports from the [related materials] below.
