Currently, the works for surveying and following up the evolution of structural pathologies of concrete structures are carried out employing digital cameras from the ground level or scaffoldings. When we face the characterisation of surfaces of dams, cooling towers, bridges or big vertical structures, many times depend on companies of work at height, having the structuralist to accept to carry out his work with the pictures provided by them, without having the chance to neither measure them, nor seeing them by himself.
Additionally, when it is about of following up the evolution of structural pathologies, we find it is not easy, since traditional photography does not support a valid dimensional characterisation. Sometimes, it can be draw on installing gauges, but it is not a simple methodology, due to the access difficulty or even hazardousness of the place where many times the pathology is located.
In this workshop we will describe how, by using drones and a technology developed by Hemav based on direct-orientation photogrammetry, it is possible to carry out photographic characterisation of concrete pathologies, including dimensional information and directly capturing their location, allowing the structuralist to easily obtain damage maps and to trace its evolution.
