A condition assessment is an essential first step to help meet the objectives for structure rehabilitation or repair, because it provides a realistic assessment of the current condition. Condition assessments help to identify the root cause of distress, and determine the state of deterioration. Based on the results of a condition assessment, owners can develop and evaluate the viability of various alternative rehabilitation concepts or determine if a replacement is necessary. While just patch repairing the structure may seem more efficient at first glance, the cost of continual repairs may...

To effectively connect the metalized anode on the surface of the concrete to the rebar, an anode connector plates is used. The plate is installed on the surface of the concrete, which is torqued onto a threaded stainless steel rod (stud), which in turn is attached to the reinforcing steel. Depending on the surface area and geometry of the structural member, the number of anode plates vary. The procedure usually includes: 1. A concrete cover meter or pachometer helps to locate the reinforcing steel where anode connector plate is to be installed. 2. A 2-inch diameter hole is made into the...

When a concrete patch is installed, fresh high pH concrete is placed in the repair area. The chemical makeup of the new concrete differs from that of the original concrete, therefore the steel in the surrounding areas of the patch is still relatively more active than the steel within the patch. The combination of having the same piece of reinforcement within the patch being passive, while the reinforcement outside the patch is being active, forms a corrosion cell that is fueled by its electrochemical imbalances. Typically, the patching procedure leaves the reinforcing steel embedded in...

Reinforced concrete structures are designed and built to function for a certain period with as little maintenance as possible. As structures age, it is in the owner’s best interest to choose a repair approach that is focused on the long-term protection of the structure to extend its service-life
