Abstract：
This study focuses on the experimental study of the application of a new single component sprayed polyurethane waterproof coating to improve the water sealing performance in water storage dam engineering, using the concrete panel of a pumped storage power station dam as a case study. The performance of the coating itself, the impermeability, the adhesion, and the weather resistance are analyzed. The results show that the new single component sprayed polyurethane waterproof coating exhibits excellent tensile performance, good durability, and su? perior bonding capabilities, which can effectively improve the water sealing performance of water storage dam engi? neering.
