A project on the production of PVC waterproofing membrane was made in the learning process. This project is important because one of the most important stages in the construction of buildings is the waterproofing of roofs and facades. Not only the quality of the roof, but also the overall condition of the building depends on the installation technology used and the quality of insulation materials. Today, the most reliable protection and the best tightness of the roof provide membrane materials. A plan of the plant and its section was developed.
