Abstract

Industrial activities generate a variety of subproducts in great quantities, which often mean waste requiring disposal. This fact is even truer in the case of petrochemical industries, where these waste products do not follow a consistent pattern. The purpose of this project was to test the use of subproducts from the synthesis of styrene and from the manufacture of telephone cables, to be used, in an innovative technology, as protection for the coverings of buildings. This technology exploits the adhesive quality of the resin and the impermeability of the compound, discarded by the cable industry, made up of two layers of a copolymer on both sides of a rolled aluminum product. The feasibility of this technology was initially tested over a small concrete slab to which the resin/compound system was applied. The properties of the system in field conditions were tested on top of the covering of a building with dimensions of 5 m x 6 m that had cracks and as a consequence let water leak through. Suitable techniques were developed for the application of the system. The field experiment proved that the proposed system is effective in eliminating infiltration in coverings, as well as being economically and environmentally appropriate. (AU)
