The durability of a building is directly linked to the humidity to which it is exposed and, once this condition is present, the acceleration of the deterioration process of structures is visibly observed through corrosion of reinforcement, problems in various coatings and the degradation of the concrete itself. Waterproofing in civil construction is extremely important in ensuring the preservation of real estate assets, habitability, building functionality, health, safety and well-being of users. Among the places that need to be waterproofed, roof slabs without a roof stand out. The objective of this work is to evaluate, based on the documentary analysis of fifteen cases for three different waterproofing systems (asphalt blanket, PVC blanket and polyurethane membrane), the degree of adhesion in the execution of waterproofing systems for roof slabs without roof in relation to good practices through the preparation of a checklist consistent with what is prescribed in normative documents and main references on the topic. Regarding obtaining the degree of total or partial adherence per stage of each case analyzed, they were obtained by dividing the number of items marked with “NO” and the sum of the number of items marked with “YES” and “NO” by completing the checklist. It was observed that, regarding the degree of adhesion, for the asphalt blanket system, cases 3 and 4 obtained a percentage of 97.22%, while cases 1, 2 and 5, 100.00%. As for the PVC blanket system, all cases obtained 100.00%. Finally, for the polyurethane membrane system, case 1 obtained a percentage of 93.10% and the others, 100.00%. Regarding the less adherent stage, there is the Application of the Type of Waterproofing. Therefore, analyzing the results obtained, the greater probability of failures occurring in cases 3 and 4 of asphalt blanket and in case 1 of polyurethane membrane is clear, all due to some mistake or error in the Waterproofing Type Application stage.
