Post-tensioned structures may become damaged by corrosion, accidental impact, brittle wire cracking, or coring and drilling after construction, leading to tendon failure. The strength and serviceability of a structure that has experienced deterioration can be evaluated and restored to its original or greater strength and serviceability. PTI published guides provide an introduction to the evaluation and repair of existing post-tensioned concrete structures to familiarize owners, licensed design professionals, contractors, suppliers, and other interested parties with the procedures, tests, equipment, and other aspects of the evaluation and repair process.

External post-tensioning can be used to increase and/or restore the capacity of most any structural element.
