中日建設株式会社／一般社団法人 IPH工法協会 Official site

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.

Due to the impact of the novel coronavirus, various restrictions have been imposed on our social lives, forcing us to live in discomfort. As a result of this impact, we regrettably had to forgo this year's "Seminar on Repairing Concrete Structures," which our association holds every July at Nagoya University. However, infrastructure repairs cannot wait even during the pandemic, so we have been making various adjustments in the hope of providing you with useful information. As a result, thanks to the kindness of Professor Nakamura from the same university, we are pleased to announce that a seminar via Zoom has been arranged as follows.

Chuo Construction Co., Ltd. / IPH Method Association will be exhibiting at the Construction Technology Fair 2019 in Chubu, held at the Fukiage Hall. This exhibition is a construction technology fair that gathers technologies from six fields: "Disaster Prevention, Safety and Security," "Maintenance Management and Preventive Preservation," "Environment and Recycling," "Design and Construction," "Robotics and AI Technology," and as a main event, "i-Construction Related Technologies Supporting the Future of the Construction Industry." We will be introducing the 'IPH Method,' which realizes the recovery of strength and improvement of durability for concrete structures. We sincerely look forward to your visit.
