Repairing corroded rebar and cracked concrete

A combination of poor rebar placement and water penetration is always the cause of rusted rebar and cracked concrete. The most common solution is simply chipping out the cracked concrete and pouring a thin layer of mortar that will last 10 years at most. Here at Sentinel, we always tackle the root of the problem. When repairing cracked concrete and degraded rebar we expose no less than 2” below the rebar in order to fully clean the rust off and set it deeper into the existing concrete before pouring our high strength mortar, so that water will not be able to further rust the rebar for another 50+ years. In extreme cases cathodic protection can also be applied in necessary cases.
