This is an "internal insertion type" sacrificial anode material that suppresses the corrosion of steel materials inside reinforced concrete structures.
"Patch Guard" is a sacrificial anode material that suppresses the corrosion of steel within reinforced concrete structures. Unlike conventional types, it is installed on the existing concrete side, where the risk of macrocell corrosion is high, making it less susceptible to the quality of backfill material, reducing the amount of chipping required, and facilitating easier backfilling. 【Features】 ■ As it is an "internal insertion type" installed on the existing concrete side, - Additional chipping is unnecessary - The risk of voids due to improper filling of backfill material is reduced - The risk of variability in construction by workers is reduced ■ Does not use an external power source ■ The anode material is compact (compared to our products), allowing for application to a wide range of structures in both construction and civil engineering ■ Effectiveness can be confirmed through monitoring *For more details, please download the PDF or feel free to contact us.

basic information
- This material suppresses the corrosion of steel by the fact that zinc (sacrificial anode) ionizes (rusts) before iron due to the difference in ionization tendency between "iron" and "zinc." - By installing the anode material on the existing concrete side, which has a high risk of re-deterioration, the corrosion of the reinforcing steel can be effectively suppressed. - This product was developed by Concrete Preservation Technologies, Inc. *For more details, please download the PDF or feel free to contact us.*
