Tunnel lining reinforcement and concrete structure reinforcement! Reducing construction labor leads to shortened construction periods.

We would like to introduce our new concrete structure reinforcement material, the 'NFK Panel Method.' In the molding plate method, the fiber sheet does not adhere closely to the deteriorated surface, so high reinforcement effects cannot be expected. However, our method integrates the entire construction area, ensuring reliable and powerful reinforcement effects. Additionally, because we use non-combustible materials (flexible boards) on the surface, it excels in fire resistance, weather resistance, impact resistance, and flexibility, providing high durability. 【Features】 - By reducing construction labor, the construction period is shortened, resulting in lower regulatory costs and reduced maintenance expenses. - The panels are lightweight and have good workability, making them less susceptible to the conditions of substrate treatment, weather, and climate, which contributes to shortening the construction period. - The change to lightweight molded panels results in minimal cross-section reduction, excellent finishing, and improved safety. *For more details, please download the PDF or feel free to contact us.*

basic information

【Solving such issues】 - Since integration with the wall is done after panel installation, it is less affected by outside temperatures and is suitable for repair and reinforcement methods in winter. - The required basis weight of continuous fiber sheets can be selected according to the condition of aging structures and the environment, tailored to the purpose. - The molded panels are lightweight, which reduces construction labor, enabling rapid installation, making them suitable for construction in high-traffic tunnels and similar environments. *For more details, please download the PDF or feel free to contact us.
