Reuse of expanded Polystyrene for waterproofing production and Application in Civil Construction

The expanded polystyrene known commercially as proportional, is very present in our daily lives, showing great uses, in this way, it has become a very popular element. Because it has high volumetric features due to its composition of 98% air and only 2% polystyrene, the recycling becomes unattractive to disrupt the environmental effects caused by its misuse. Currently, the use of technologies in conjunction with alternative inputs, such as styrofoam, are considered major innovations for the civil engineering market, with a tendency to provide cheaper construction, achieving excellent results. This work aims to reuse expanded polystyrene for the production of waterproofing using solvents and vegetable oil. The present work has shown positive results capable of protecting the building elements and components against harmful water actions.
