[0002] As my country's urbanization accelerates, built-up area is increasing dramatically, while urban green space is shrinking. Simultaneously, gases released by various energy consumption and vehicle exhaust are increasing, exacerbating the "heat island" effect and worsening the urban ecological environment. One effective way to alleviate these contradictions is to develop green roofs. Green roofs protect roof surfaces and reduce UV damage, but the plant roots in green roof systems are highly penetrating. If the waterproofing material is not properly selected, these roots will penetrate the building, causing leakage.

The structure comprises a structural layer, a slope leveling layer, an insulation layer, and a leveling layer, arranged from bottom to top; a waterproof and root-penetration-resistant layer; a drainage layer; and a filter layer. The waterproof and root-penetration-resistant layer utilizes a modified asphalt waterproofing membrane, which may be a composite copper-based modified asphalt waterproofing membrane or a chemical root-blocking modified asphalt waterproofing membrane. This utility model has the dual functions of waterproofing and preventing plant root penetration, is puncture-resistant, tear-resistant, has high tensile strength, high elongation, strong adaptability to base layer shrinkage, deformation, and cracking, and is resistant to high and low temperatures, corrosion, mildew, and weathering.
