双防水屋面由预制屋面板板面自防水与冷涂料贴板缝防水层(第一道防水层)、找平隔离层、预应力刚性防水层(第二道防水层)三部分组成(图1)。双防水屋面的第一道防水层是在自防水屋面和冷涂料防水屋面的基础上发展起来的,第二道防水层是在预应力刚性防水屋面的基础上发展起来的。双防水屋面不仅造价低,而且耐久性好,维修费用低,足一种经济效益较好的屋面防水形式。
Double waterproof roof consists of three parts: prefabricated roof panel surface waterproof and cold paint patch waterproofing layer (first waterproof layer), leveling insulation layer, prestressed rigid waterproof layer (second waterproof layer) (Figure 1) . The first waterproof layer of the double waterproof roof is developed on the basis of self-waterproof roof and cold paint waterproof roof. The second waterproof layer is developed on the basis of prestressed rigid waterproof roof. Double waterproof roof not only has low cost, but also has good durability and low maintenance cost. It is a roof waterproofing mode with good economic benefits.
