Internal reinforcement method (partial repair)

For pipe inspection, repair, and correction, please leave it to us.

Our company has a specialized machine that attaches a thermosetting resin repair material to glass cloth and non-woven fabric. This machine is moved from the manhole to the repair site and is used for the "internal reinforcement method (partial repair)" to adhere to the areas of the sewer pipe that need repair. After being pressure-bonded, it is heated and cured with a heater. Additionally, light curing using ultraviolet radiation is also possible, allowing us to adapt the construction to customer requests and the conditions of each site. Since the work is carried out while confirming with a television camera, there is no need to excavate the ground, and construction can be performed without interrupting the use of the sewer system. By repairing the sewer pipes themselves, we extend the lifespan of the sewer pipes, stop leaks, and prevent accidents such as road subsidence. 【Features】 ■ Fast construction is possible through pressure and heat curing (light curing) (approximately 1 hour per location) ■ Consistent repairs from the installation pipe opening to the main pipe section using a television camera-equipped branch repair machine ■ Repairs for steps, joint misalignment, pipe misalignment, bends, etc., are possible with the main pipe (variable) repair machine ■ Repairs inside the installation pipe using the installation pipe internal repair machine *For more details, please feel free to contact us.
