The growing relevance that it has reached in the current society the refurbishment, rehabilitation, conservation and maintenance of existing buildings and infrastructures, in particular the historical heritage, has revealed the need to calibrate effective methods of analysis, planning and implementation of the constructions rehabilitation measures, as well as maintenance and management strategies. This will amplify economic flows destined to the rehabilitation sector, and hence, the need to improve the mentioned methodologies. Similarly, there is a prevailing need to consolidate a debate forum in order to update the state of knowledge of the technologies applied to diagnostics, rehabilitation, maintenance and management of the built heritage. REHABEND Congresses on ‘Construction Pathology, Rehabilitation Technology and Heritage Management’ aim to bring together the progress made in recent years in the theoretical and experimental knowledge carried out in these topics. The main aim of the event is to promote the knowledge transfer between different countries who are working on this field of research. This volume contains the abstracts presented at the REHABEND 2018 conference, which was carried out in Caceres, Spain, May 15th – 18th, 2018.
