It is a patented product launched by Golden Umbrella. It is a new product specially developed to solve the problem of water leakage caused by ordinary rolling materials that cannot be effectively bonded to the base surface. It can be compared with the current Poured concrete or cement slurry initiates a chemical cross-linking reaction, and is firmly bonded to the concrete base through the synergistic effect of chemical cross-linking and physical mortise and tenon joints. Because it reacts and bonds with the base layer to form an interface sealing layer, it can build a "binary" waterproof layer structure on the concrete base layer similar to the coating layer and the membrane layer, which can adapt to the influence of cracking and deformation of the base layer and provide long-term waterproofing effect. It is particularly suitable for waterproofing projects with higher waterproofing levels, poor construction environments, humidity, and tight deadlines. At present, there are few companies at home and abroad that are committed to solving the problem of reactive bonding between membranes and concrete base layers. The main products now include reactive butyl rubber waterproofing membranes from Yoshida of Japan and Grace of the United States, and CPS reactive bonding type of Golden Umbrella. Compared with pre-paved/wet-laid waterproofing membranes and Golden Umbrella’s CPS reaction-bonded pre-paved/wet-laid waterproofing membranes in terms of price and waterproof performance, they are more suitable for practical applications in China’s waterproofing projects.
