目前种植屋面的防水材料较多采用的是SBS改性沥青耐根穿刺防水卷材,该卷材一般采用热熔的方式进行施工处理,但在施工过程中往往容易发生过烧、搭接不密实、收头处理不当等施工缺陷,继而导致其防水性能的失效,从而直接影响防水效果。以工程实际为例,阐述了SBS改性沥青耐根穿刺防水卷材的正确做法及施工注意事项,同时也介绍了种植屋面系统的部分节点构造,可供种植屋面系统的防水施工参考。
At present, the waterproof material used for planting roofs is mostly SBS modified bitumen-resistant waterproofing membrane, which is usually processed by hot-melt method. However, during the construction process, it is easy to over-burn and lap-dense , Closing the first improper handling and other construction defects, which led to the failure of its waterproof performance, which directly affects the waterproof effect. Taking engineering practice as an example, the correct practices and construction precautions of SBS modified asphalt root puncture waterproofing membrane are expounded. Some node structures of planting roofing system are also introduced, which can be used as waterproof reference for planting roofing system.
