"Z Mortar S-1" is a premixed type of thick coating fiber-reinforced rapid-hardening repair mortar that has excellent early strength and durability, as well as good workability. Unlike conventional cement-based repair materials that require multiple layers of application (thickness for vertical surfaces: 10-40mm), it can be applied in one spraying or troweling operation. In spraying operations, rebound loss is minimal, and troweling work is also satisfactory. 【Features】 ■ Excellent workability ■ Superior early strength, allowing for significant reduction in construction time along with good workability ■ The hardened material exhibits excellent wear resistance ■ Has excellent compatibility with various finishing materials for concrete *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 conforms to the quality standards for sulfuric acid-resistant mortar for protective coatings as specified in the Japan Sewage Works Agency's "Manual on Corrosion Control Technology and Protective Technology for Sewage Concrete Structures." Designed with a concept that allows for a reduction in cross-section, it predicts the amount of cross-sectional reduction or depth of carbonation due to deterioration, setting a cross-sectional reduction amount or carbonation depth that does not pose structural problems, or it involves pre-thickening the cross-section and repeatedly performing repairs while conducting regular inspections to maintain the facility's functionality. 【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 environments with high moisture content in concrete, which conventional coating-type lining methods cannot accommodate. ■ Eliminates the need for overlapping processes in coating-type lining methods, resulting in shorter construction processes and curing periods, thus reducing construction time. ■ Reduces resource use, energy consumption, and CO2 emissions through the use of blast furnace slag. *For more details, please refer to the PDF document or feel free to contact us.

The "Zick Board Method" falls under the sheet lining method and is a concrete corrosion protection coating method suitable for facilities in extremely harsh environments or those requiring long-term durability. A multi-layer molded board (Zick Board) is formed by integrally molding a three-dimensional cross on the back 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 corrosion protection layer. 【Features】 - Suitable for facilities in harsh environments or those requiring long-term durability - Provides excellent barrier properties with a homogeneous high-density corrosion protection 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 the coating layer from cracking due to structural cracks and damage *For more details, please refer to the PDF document or feel free to contact us.
