 The reclamation of construction solid wastes is crucial for the high-quality development of the construction industry and it is urgent to further improve the utilization rate of the construction solid wastes to achieve the carbon peaking and carbon neutralization goals. Waste waterproof materials are an important component of the construction solid wastes; however, research on the utilization of these materials is almost blank in China. As calculated in this study, the total output of waterproof materials in China was 2.983×1010 m2 during 2005‒2021 and that of waterproof membranes was 1.89×1010 m2, indicating that waterproof membranes are the main body for waterproof material recycling. In response to the national green and low-carbon development situation, a utilization path for “reducing, reusing, and recycling” (3R) the waterproof membranes is proposed as well as a high-performance waterproof membrane research and development concept that combines waterproof membrane “genome”, multi-scale / multi-scenario
