Application Summary AI generated
GB 23440-2009 specifies technical requirements, test methods, and quality criteria for inorganic waterproof and leakage-preventing materials used in building construction. It applies to cement-based or other inorganic powder materials applied as coatings or plugging agents to seal cracks, joints, and structural leaks in concrete and masonry structures. The standard is primarily used in civil engineering projects, such as basements, tunnels, roofs, and water-retaining structures, to ensure reliable waterproofing performance.
