Parâmetros e seleção de sistemas impermeabilizantes em laje de coberta: um estudo de caso de edifício residencial na cidade de João Pessoa/PB

Abstract

The construction industry has experienced in recent years a relevant growth, raising the levels of current buildings with the emergence of technological innovations in various areas of engineering. Because it is a very competitive market, and in order to meet the requirements of a market niche with increasingly demanding consumers, entrepreneurs in the construction industry should get increasingly invest in the proofing stage, increasing the useful life of buildings and seeking a competitive advantage. Waterproofing projects are considered quite effective as a means of communication in the work, allowing adequate guidance in the selection process of the waterproofing system, ensuring the best performance of the building. This work aims to identify the parameters of the use and application of waterproofing materials cover slabs using flexible membranes acrylic base. The methodology consisted of first raise the main waterproofing systems used, subsequently accompanied-if the step of proofing a building composed of 18 floors kind, seeking to carry out an analysis of how the process was executed and where could arise even failures, and finally the last step was to perform laboratory tests in order to obtain the water absorption index using acrylic membrane where we used the product Tecryl D3, and the use of polymer mortar, where Viapol 1000. The results obtained demonstrate the relevance of the topic, showing that the management of a suitable waterproofing process results in more and more durable structures.
