The structural hierarchy of the planted roof generally includes a concrete base layer, a waterproof layer and a planted layer.
Concrete is essentially a heterogeneous porous material. In the environment of long-term contact with water, the concrete material is permeated into the pores of the concrete due to the fact that the water is taken as a solvent and carries chloride ions, carbon dioxide and some microorganisms, so that the microstructure of the concrete matrix is damaged. And the concrete matrix is easily cracked due to the increase in volume of free water in a low temperature environment.
Existing waterproof layers are typically formed from asphalt (typically high viscosity, high elastic modified asphalt) and a polymer (e.g., EVA, PE, SBR) that melt under heat to form a cohesive material. The material has certain deformability and good waterproof property, and has the defects of poor high-temperature stability and lower bonding strength, and the formed waterproof layer has poor adhesion performance with concrete and poor waterproof performance
