Application Summary AI generated
GB/T 18173.3-2014 specifies the technical requirements, test methods, inspection rules, and marking for hydrophilic expansion rubber used as a waterproof sealing material. It is applied in construction and civil engineering for sealing joints, gaps, and penetrations in concrete structures such as tunnels, subways, water treatment plants, and underground parking garages, where the rubber expands upon contact with water to create a watertight seal. This standard is critical for quality control and procurement in industries requiring reliable waterproofing in wet or submerged environments.
