The invention discloses a waterproof roll with two waterproof layers and a construction process thereof. The waterproof roll comprises a first waterproof layer and a second waterproof layer, the second waterproof layer is sequentially provided with a sand layer, a first hot melt adhesive layer, a connecting film layer and a second hot melt adhesive layer from top to bottom, and the second hot melt adhesive layer is bonded with the first waterproof layer. Wherein the first hot melt adhesive layer is a styrene-isoprene-styrene adhesive layer; the second hot melt adhesive layer is one or a composite layer of more than two of a styrene-isoprene-styrene adhesive layer, a butyl adhesive layer and an asphalt modified adhesive layer, so that both the first hot melt adhesive layer and the second hot melt adhesive layer can realize a self-adhesive function, and self-adhesive can resist permeation of small molecular substances or hybrid substances from the hot melt adhesive layers; therefore, the two hot melt adhesive layers in the second waterproof layer still keep relatively good cohesiveness after being used for a long time. The viscosity between the first waterproof layer and the second waterproof layer can be kept, the water channeling resistance is improved, and the waterproof requirements of indoor and outdoor buildings can be effectively met.
本发明公开了一种两道防水的防水卷材及其施工工艺，该防水卷材包括第一防水层和第二防水层；第二防水层从上到下依次设有砂子层、第一热熔胶层、连接膜层和第二热熔胶层，第二热熔胶层与第一防水层粘合。其中，第一热熔胶层为苯乙烯一异戊二烯一苯乙烯胶层；第二热熔胶层为苯乙烯一异戊二烯一苯乙烯胶层、丁基胶层和沥青改性胶层中的一种或两种以上复合层，所以第一热熔胶层和第二热熔胶层均能实现自粘胶功能，自粘胶能够抵抗来自热熔胶层的小分子物质或杂性物质的渗透，使得第二防水层中两层热熔胶层在长时间使用下仍然保持较好的粘结性。能保持第一防水层和第二防水层之间的黏性，提高抗窜水性能，能有效满足室内外建筑的防水要求。
