Introducing Repair Star with a lineup that can be chosen for civil engineering, construction, and injection use!
"Repair Star☆NF (for civil engineering)" is a premixed type of sectional repair mortar that can be used by adding a specified amount of water and mixing it during use. It excels in workability, durability, and fire resistance, and demonstrates its performance when used in a wide range of fields, including repair and reinforcement work for bridges and tunnels, seismic reinforcement work in civil engineering and construction, and repair work for marine structures (electrolytic corrosion prevention). Additionally, we offer "Repair Star☆NP" for construction use and "Repair Star☆G" for injection. 【Features】 <Repair Star☆N> ■ Can be applied using either plastering methods or wet spraying methods ■ Excellent salt resistance, suitable for repair of marine structures and measures against salt damage deterioration ■ Superior resistance to carbonation, freeze-thaw damage, and fire ■ Due to its inorganic material composition, it has physical properties close to concrete ■ Excellent adhesion performance, high strength, and crack resistance *For more details, please refer to the PDF document or feel free to contact us.
