增强聚酯布防水材料要求非常符合规范，出厂前经过多道检测工序，有相应资质等级检测部门出具的检测报告。聚酯布防水层空鼓，发生在找平层与聚酯部之间，且多在聚酯布接缝处，其原因是找平层不干燥，汗水率大，空气排除不彻底，聚酯布没有粘结牢固；渗漏多发生在管根、地漏、形变缝等处，伸缩缝没有断开，造成防水层撕裂，其他部位由于粘结不牢固也有可能发生渗漏，施工中应该加强检查，认真操作。
The waterproof material of reinforced polyester cloth meets the specification very well. It has been tested in several procedures before leaving the factory and has the test report issued by the testing department with corresponding qualification level. The waterproof layer of polyester cloth is hollowing, which occurs between the leveling layer and the polyester part, and mostly at the joint of polyester cloth. The reason is that the leveling layer is not dry, the sweat rate is large, the air is not completely removed, and the polyester cloth is not firmly bonded. The leakage often occurs at the pipe root, floor drain, deformation joint, etc., the expansion and contraction joints are not broken, causing the waterproof layer to tear, and other parts may also occur due to the weak bonding For leakage, inspection shall be strengthened and operation shall be carried out carefully during construction.
屋面隔离层的做法应在施工中因地制宜，取长补短，把面上的这三涂一布防水层做在找平层与刚性层之间，既起了隔离层的作用，又不被日晒雨淋，既防止老化，又起了防水作用。防水工程在建筑施工中属于关键项目和隐蔽工程，对保证工程质量具有重要意义。
The method of roof isolation layer shall be adapted to local conditions during construction, and the advantages and disadvantages shall be supplemented. The three coats of one cloth waterproof layer on the surface shall be used between the leveling layer and the rigid layer, which not only plays the role of isolation layer, but also is not exposed to the sun and rain, which not only prevents aging, but also plays the role of waterproof. Waterproof project is a key project and concealed project in the construction, which is of great significance to ensure the quality of the project.
