High-density filling with ultra-low pressure injection even for fine cracks of 0.01 mm. Significant reduction in construction time and cost compared to conventional methods is possible! *2020 version of the construction case study collection published.

The conventional concrete repair method known as "low-pressure resin injection" often fails to reach the internal structure of the concrete due to the obstruction of air inside. In contrast, the concrete repair and reinforcement method "IPH method" allows the injected resin to diffuse radially within the concrete while removing the air present inside the structure, effectively filling even the finest cracks at the ends. This filling enhances the bond strength between the rebar and concrete, providing anti-corrosion effects as well. Recently, there have been many successful applications in public works projects such as tunnels and bridges, and inquiries from private large facilities and factories have significantly increased in recent years! ~ We are currently offering the latest construction case collection for download as a PDF! ~ 【Features of the IPH Method】 ■ Extracts air from inside the cracks and releases it outside ■ Achieves high-density filling through ultra-low-pressure injection ■ Restores and enhances the strength of the internal structure ■ By filling voids, it provides water-stopping, anti-corrosion effects, neutralization suppression, and salt damage countermeasures ■ Can be performed without stopping facility usage * For more details, please refer to the PDF materials or feel free to contact us.
