Coating-type lining with high chemical resistance.
▼Overview We propose corrosion prevention measures for sewer facilities that meet the required performance and functionality, offering cost reduction and longevity strategies based on years of experience. We have various construction methods using different materials to suit specific applications. Additionally, it may be more cost-effective compared to sheet lining methods. Each lineup excels in "adhesion stability," "sulfuric acid resistance," and "barrier properties." ▼Features Using a construction method that applies high chemical-resistant vinyl ester resin, Type B is a laminated specification (without reinforcement), while Types C and D are laminated specifications with reinforcement (glass mat lamination), demonstrating excellent performance even against high concentrations of chemicals. *Immersion tests were conducted with 10% acetic acid.

Company information
Nihon Jikkou is a core company of a comprehensive engineering group that contributes to society through the production and sale of various related materials, starting with concrete anti-corrosion construction. Japan is now entering an era of high prevalence of social infrastructure such as water supply and sewage systems, with a vast number of concrete facilities being stockpiled. However, as these facilities age and deteriorate, it has become an urgent issue to systematically and effectively implement repair and maintenance measures to sustain them in the future. Nihon Jikkou and its group companies address these challenges by proposing optimal deterioration prevention measures based on environmental factors and facility characteristics, along with excellent construction techniques, thereby meeting all maintenance and management needs for concrete structures.
