Patching of corrosion-damaged concrete is by far the most common concrete repair procedure, comprising a significant portion of the total repair market. In some cases, rebar corrosion has progressed to the point where the concrete member must be replaced. But in most cases, partial-depth patching is sufficient to prevent further deterioration and extend the service life of the structure.
To install durable partial-depth patches, contractors must adhere to several tenets of good concrete repair practice: proper concrete removal, thorough surface preparation and rebar cleaning, careful material selection, and adequate curing. Failure to follow these steps can lead to failure of the partial-depth repair.
