Design of expanded polystyrene-based waterproofing

Abstract

Plastic pollution, especially expanded polystyrene (EPS), is a significant problem worldwide, and El Salvador is no exception. EPS, commonly known as Styrofoam, is used in plates, cups, and product packaging, but its poor disposal and slow decomposition negatively affect ecosystems and human health. To address this problem, the development of a waterproofing material for exterior walls made from recycled EPS is proposed. This initiative seeks to transform a polluting material into a construction solution that reduces humidity in buildings and the demand for new resources, helping to mitigate plastic pollution. The research is justified by the need for sustainable alternatives and is based on theories of sustainable development and previous studies on EPS pollution. The results have the potential to be applicable in various locations, promoting innovative reuse of this material.
