description The utility model relates to a tension-fracture-preventing waterproof layer structure. The tension-fracture-preventing waterproof layer structure comprises a surface layer which is laid on the uppermost surface of a roof, wherein the surface layer is an SBS elastomer modified asphalt waterproof layer, a middle layer is a nonwoven fabric layer, and a bottom layer is a polyacrylate pressure-sensitive adhesive layer; and the nonwoven fabric layer is formed by three layers, the upper layer and the lower layer are respectively formed by smooth nonwoven fabrics, and the nonwoven fabric of an intermediate layer is a nonwoven fabric with corrugated wrinkles. Three layers of coatings and coiled materials are adopted for the tension-fracture-preventing waterproof layer structure, so that the water leakage of the roof caused by the tension fracture phenomenon of the roof can be effectively prevented.
