We Sounded, Marked, And Measured The Delaminated Concrete, So Why Wouldn’t Those Measurements Be Enough To Cover All Of The Repairs?
Concrete becomes delaminated when it has lost grip of the reinforcing bars due to corrosion. The corrosion has expanded the reinforcing bars, creating a gap between the concrete and sound metal. It is common for the area around the delaminated concrete to also contain corroded reinforcement, which is almost ready to become delaminated; Therefore, when concrete repairs are performed, contractors are to “chase” the corrosion found on the reinforcement, expanding the patch until solid reinforcing bars have been reached. If contractors only replace what is currently delaminated, repaired patch perimeter areas will soon become delaminated, and will compromise the repair which has recently been completed.
