Application Summary AI generated
GB/T 21897-2008 specifies requirements for load-bearing waterproof sheets, which are composite materials combining waterproofing and structural load-bearing capabilities. It is applied in civil engineering projects such as underground structures, tunnels, and roof gardens where the sheet must resist water penetration while supporting overlying loads like soil, vegetation, or pedestrian traffic. The standard defines testing methods for tensile strength, tear resistance, and watertightness under mechanical stress, ensuring performance in construction and infrastructure applications.
