Rehabilitation is possible regardless of the shape of the manhole (circular or rectangular).
The Zickboard M method is a construction technique that combines the performance required for manhole rehabilitation and corrosion prevention. The Zickboard is installed with a gap on the inner surface of the existing manhole, and Zick grout is filled into this gap. This allows the three-dimensional cross on the back of the Zickboard and the Zick grout to interlock firmly, integrating the Zickboard with the existing manhole to withstand external forces. ▼Features - It can be adapted to facilities in extremely harsh environments or those requiring long-term durability. - The Zickboard is a factory-molded product with a homogeneous, high-density corrosion-resistant coating that has excellent barrier properties, preventing the penetration of corrosive substances. - The joints are designed with a double structure of molded products and corrosion-resistant seals, providing excellent durability features that prevent damage to the joint area due to stress concentration and other factors.

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.
