Application Summary AI generated
GB 18242-2008 specifies the requirements, test methods, and inspection rules for SBS modified bituminous sheet materials used as waterproofing layers in building construction. It applies to roofing, underground structures, bridges, and tunnels where flexible, durable waterproof membranes are needed to withstand temperature variations and structural movement. The standard ensures material performance in terms of tensile strength, elongation, low-temperature flexibility, and heat resistance for both factory production and field acceptance testing.
