The disorderly and unplanned growth of large urban centers tends to aggravate the process of coastal erosion, becoming a problem that has been impacting about 40% of the world's population that lives in coastal areas. The present study aimed to present the BetonBloc system, which consists of the construction of walls composed of concrete blocks without the use of reinforcement, as an alternative for maritime containment located in the municipality of Ipojuca -PE. The methodological process began with the analysis of satellite images, with the aim of identifying urban transformations over the years in the study area. Then, through studies of beach profiles, with measurements before the beginning and after completion of the work, an analysis was made of the efficiency of the system. As a result, there was an increase of 257% in the urbanized area and a reduction of 72% and 46% in the areas of water bodies and natural vegetation, respectively. In all measurements taken, the beach profile after the work is higher than the profile before the work. Therefore, the system showed satisfactory efficiency, standing out as a procedure that is quick to perform, durable and does not require short-term maintenance.
