Abstract
A method for installing a new steel tendon and for repairing a damaged or deteriorated steel tendon in a prestressed concrete slab is disclosed. The repair method includes the steps of relieving substantially all stress in the defective original tendon, removing the original tendon, installing a new tendon in the space vacated by the original tendon, installing new concrete around the new tendon to replace any original concrete removed while removing the original tendon, and stressing the new tendon thereby again prestressing the previously structurally defective slab. Installation of a tendon where none has previously existed is similar except an original tendon need not be removed.
