The "Zick Board Method" falls under the sheet lining method and is a concrete anti-corrosion coating method suitable for facilities in extremely harsh environments or those requiring long-term durability. A multilayer molded board (Zick Board) is formed by integrally molding a three-dimensional cross on the backside of a high-durability vinyl ester resin FRP sheet, which is then directly bonded to the structural concrete or the poured concrete through acid-resistant inorganic grout, creating an integrated anti-corrosion coating layer. [Features] - Suitable for facilities in harsh environments or those requiring long-term durability - Provides excellent barrier properties with a homogeneous high-density anti-corrosion coating layer - The joints of the post-application method prevent damage to the joint area due to stress concentration, imparting excellent durability functions - The three-dimensional cross prevents common cracking of the coating layer due to cracking damage in the structure *For more details, please refer to the PDF document or feel free to contact us.

The "Z Mortar KS500 Method" is a corrosion protection method using sulfuric acid-resistant mortar based on blast furnace slag. It complies with the quality standards for sulfuric acid-resistant mortar for protective coatings as specified in the Japan Sewerage Agency's "Manual on Corrosion Control Technology and Protective Technology for Concrete Structures in Sewers." Designed with a concept that allows for a reduction in cross-sectional area, it predicts the amount of reduction in cross-section or the depth of carbonation due to deterioration, setting a reduction amount or carbonation depth that does not pose structural issues. Alternatively, it involves pre-thickening the cross-section and maintaining the facility's functionality through repeated repairs while conducting regular inspections. 【Features】 ■ Exhibits excellent sulfuric acid resistance due to the formulation of special powders based on blast furnace slag. ■ Can be applied in high humidity environments and construction conditions with high moisture content in concrete, which conventional coating lining methods cannot accommodate. ■ Eliminates the need for overlapping processes in coating lining methods, resulting in shorter construction processes and curing periods, thus reducing construction time. ■ Reduces resource and energy consumption, as well as CO2 emissions, by using blast furnace slag. *For more details, please refer to the PDF document or feel free to contact us.
