导致地下柔性卷材防水施工失败的主要因素是“水”。这是与屋面卷材防水在施工上的主要区别。由于地下卷材施工中经常拖泥带水,致使沥青涂敷不牢,卷材粘结不良,搭边封皮不严等问题出现。所以,地下卷材防水施工成败的关键是施工现场的干燥、洁净与否。 The main factor leading to the failure of waterproof construction of underground flexible coils is “water”. This is the main difference between construction and roof waterproofing. Due to the frequent dragging of water in the construction of underground coils, the problem of poor coating of asphalt, poor adhesion of the coiled material, and inconsistent overlapping of the cover and the like occur. Therefore, the key to the success of submerged coil waterproof construction is the dryness and cleanliness of the construction site.
