PRACTICAL PATCHING

Patching of corrosion-damaged concrete is by far the most common concrete repair procedure. For many of these repairs, partial-depth patching is sufficient. To install durable partial-depth patches, however, 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. This article outlines these procedures and examines whether bonding agents and rebar coatings are needed. Failure to follow the outlined steps contributes to what many consider an unacceptable failure rate of partial-depth repairs.
