Reduction of life cycle costs with a durability of 50 years.
▼Overview The Zick Board GR method has a construction track record of over 20 years, and based on follow-up survey results of operational facilities and promotion test results, it has been verified that even 50 years after completion, it can maintain the performance of "adhesion stability," "sulfuric acid resistance," and "barrier properties," ensuring a service life of 50 years. By having a service life of 50 years, it enables a reduction in lifecycle costs compared to coating-type lining methods and other sheet lining methods. ▼Features - The joints of the Zick Board GR method have a triple structure consisting of FRP molded products on the surface and back, along with corrosion-resistant sealing materials, providing excellent durability functions that prevent damage to the joint area due to stress concentration and other factors. - The Zick grout injected into the back of the Zick Board can also serve as a cross-section restoration process after the removal of deteriorated areas during renovation work.

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.
