Abstract
A construction structure includes a substrate made of a concrete material and has an external surface, and a reinforcement attachment made of a metallic material having an outwardly facing surface and an inwardly facing surface. The attachment is secured to the substrate with the inwardly facing surface bonded to the external surface of the substrate, and has first portions and second portions. At least one of the surfaces of a first portion of the attachment is pre-treated and attached to the substrate such that when the construction structure is under loading the first portion(s) block(s) or reduce(s) spreading of strain sustained by the attachment along the attachment to avoid or at least delay complete detachment of reinforcement from substrate.
