An Innovative Three-layer Membrane System Intended for the Renovation of Water and Sewage Infrastructure Facilities Exposed to Aggressive Sulfate Environment

dc.abstract.enProgress in the repair and protection of water and sewage infrastructure currently focuses on the use of a modern and innovative material in the form of polyurea, distinguished by its fast hardening properties and versatility of use, applied with a spray gun using high-pressure pumps. The development of new building materials is part of an ongoing effort to meet stringent environmental, health and performance standards, with polyurea offering significant improvements by eliminating solvents and volatile compounds (VOCs). The application process includes a detailed protocol (technological regime), starting from inspection and cleaning, through drying, to the application of three layers: a base layer to block moisture, a middle layer of rigid polyurethane to strengthen the structure, and a final sealing and anti-corrosion layer. This method guarantees a monolithic structure without joints, increases strength thanks to the rigid polyurethane and speeds up the repair process, allowing immediate return to service after application. Specifically designed for use in aggressive wastewater environments, this system provides excellent corrosion resistance, making it an ideal solution for wastewater infrastructure components such as reinforced concrete wells, sewage pumping stations and tanks. The ability to adjust the properties of polyurea allows for personalization in terms of environmental aggressiveness, size of the protected structure and abrasion resistance, marking a significant advance in infrastructure maintenance technology.
