Seawall Repair Network® contractors offer seawall stabilization and seawall preservation services. This article is a deep dive into the application and characteristics of the Seawall Repair Network® concrete preservation products that could be used to protect your seawall.
All concrete surfaces need to be pressure washed before the application of any of the following products.
SW-Power (Apply This Product First)
SW-Power is a multi-phase, inorganic, surface-applied corrosion inhibitor for use on hardened concrete. It is designed to protect reinforcing steel in concrete from corrosion on multiple fronts by penetrating the concrete surface and migrating to the steel. SW-Power forms a passivating film on the steel surface which provides protection from the corrosion process thereby extending the service life of the structure. SW-Power functions on multiple fronts to deliver superior performance. In addition to creating a passivating film on the surface of the embedded reinforcement SW-Power inhibits and prevents corrosion by increasing electrical resistance, complexing and removing water-soluble chlorides, re-alkalizing areas of carbonation, and stopping water penetration and diffusion. In addition, SW-Power has been shown to improve substrates strength. In some cases, SW-Power will purge impurities from the concrete surface. If this happens, the surface will need to be pressure washed again to remove the purged impurities before moving to the next step.
SW-Prevent (Apply Next, To Entire Surface or Just Hot Spots)
SW-Prevent is an organic, surface-applied anodic and cathodic site corrosion inhibitor for use on hardened concrete. It is designed to protect reinforcing steel in concrete from corrosion by penetrating the concrete surface and migrating, in liquid and vapor form, to the reinforcing steel. SW-Prevent forms a passivating film on the steel surface which provides protection from the corrosion process, thereby extending the service life of the structure. SW-Prevent is a vapor-phase corrosion inhibitor (VCI) for concrete. It penetrates easily as gas and affects steel properties at both the anodic and cathodic sites. Due to its high penetrative ability minimal or no surface removal is required for the SW-Prevent to be highly effective at the rebar depth. SW-Prevent is especially effective in areas of corrosion “hot spots” and instances of chloride-induced corrosion. For maximum corrosion protection SW-Prevent is recommended for use in combination with SW-Power.
SW-Protect (Apply This Product Last)
SW-Protect is a ready-to-use mixture of silane and siloxane water repellents that provide complete protection against water intrusion and further improve the performance of SW-power and SW-Prevent to resist water penetration and inhibit corrosion. SW-Prevent is a UV Resistant, cannot be peeled or scratched off, is VOC compliant, breathable, and easy to apply. Its performance has been laboratory tested and proven in the field to provide superior protection against atmospheric pollutants, waterborne pollutants, mold and mildew formation, etc.
