Concrete repair and reinforcement method "IPH method (internal pressure filling joint reinforcement)"
Of course, crack repair, as well as extending the lifespan of concrete structures and preventing re-deterioration. This method allows for high-density filling at the ends while injecting while removing air.
Tsuchiya Construction, which operates in the general construction industry, handles the internal pressure filling joint reinforcement method known as the 'IPH method.' This method achieves "strength recovery" and "extended lifespan" for concrete structures that have deteriorated due to aging or earthquakes. It is a special technique that injects resin while extracting air from within the concrete, allowing the resin to diffuse radially from the drilled holes and fill even the finest cracks at the ends. This not only enhances the adhesion strength between rebar and concrete but also provides anti-corrosion effects, contributing to improved durability. 【Features】 ■ Strength recovery and increased load capacity of concrete structures ■ High-density filling to the finest cracks at the ends ■ Improved durability due to anti-corrosion effects ■ Technological evaluation from the Japan Society of Civil Engineers and patent acquisition for the method 【Construction Example: Kamishima Monitoring Post in Mie Prefecture (Photo)】 We restored a building that had been prohibited from use due to aging and prepared it for use as a tourist facility. 【Strengths of Tsuchiya Construction】 We handle a variety of methods and excel at providing proposals tailored to site conditions. We can provide consistent support from preliminary diagnosis to post-repair inspection. Please feel free to contact us! *Method information can be viewed in the catalog available for [PDF download].
