Chubu Nippon Highway Engineering Nagoya Co., Ltd. (Engineering Nagoya) offers a "Composite Corrosion Prevention Method" that is an efficient repair technology for concrete members suffering from deterioration such as delamination due to rebar corrosion caused by salt damage, capable of "suppressing rebar corrosion over the long term." By using sacrificial anode materials (immediate effect) combined with high-concentration rust prevention mortar (long-term effectiveness), we can stop salt damage with a double effect. This method can reduce the "chipping depth" in cross-section repair work, thereby lowering the risk of re-deterioration. Additionally, it allows for a reduction in the need for specialized technical elements. 【Features】 ■ Economic, safe, reliable, and simple ■ Reduction of re-deterioration risk ■ Decrease in the need for specialized technical elements ■ Long-term suppression of rebar corrosion *For more details, please refer to the PDF document or feel free to contact us.
