When planted roof is a flexible waterproof layer, but also set up a layer on top of the rigid protective layer. That is, you can use one or more roof channels (composite) waterproof fortification, Huayin hotel roof garden, but the top one should be rigid waterproof layer, Yan'an hotel roof garden, roof flashings waterproof layer should be higher than the height of the overflow opening 100 mm rigid roof waterproof layer due to thermal expansion and structural deformation of the floor by the impact, should irregular cracks caused by the failure of rigid waterproof roof. To solve this problem, in addition to 30 to 50 mm thick, fine stone concrete steel wire or steel mesh configuration, in general, can be solved by building a floating layer and dividing joint and other methods. That so-called floating building layer insulating layer, and the structure of the rigid waterproof layer waterproof layer apart to accommodate the deformation of activities. Construction practice in the floor screed, Chenggu hotel roof garden, laying a layer of dry felt or waste paper to form an insulating layer, and then do a dry waterproof layer. Insulation layer may also be utilized ash or sand and other loose material on the floor forming an isolation layer, then do rigid waterproof layer. Dividing joint dry waterproof layer is determined based on the temperature of stretching and structural slab deformation and other factors, according to a certain sub-grid set aside 20 mm wide slit, to facilitate stretching in the seam filling gel clay. Note: Due to rigid waterproof layer ruled seam construction quality is often not guaranteed, except at the parapet flashings should be strict requirements to do sub-lattice seam, the roof may not be provided the rest of sub-lattice seam. Rigid waterproof roofing layer preferably all at once, pouring is completed, in order to avoid leakage. Waterproof layer surface must be smooth, until the construction is completed, two waterproof paint brush to ensure that the design and construction quality of the protective layer waterproof layer. Pay particular attention to the waterproof layer anti-corrosion treatment, Weinan hotel roof garden, cell waterproof layer seam can be "a four-coated cloth" cover seam, and good corrosion resistance selection caulking ointment. It should not be planted root system, strong waterproof layer erosion plants, such as pine, cypress, banyan. Reasonable selection is the key to achieving a comprehensive technical and economic effect. The main principle is to choose its structure, geographical location, weather conditions, water level, waterproof layer structure, waterproof parts and construction and other building according to the importance of detail; feature selection based on the local climate waterproof material; waterproof material based on performance, waterproof rating requirements, determine the thickness of the water layer. Now waterproof material variety, product quality varies greatly. Designers should fully understand the properties of these materials, the correct choice of quality waterproof material, consisting of both economic rationality, but also give full play to the effect of the waterproof layer. Roofing major projects, particularly high-rise building roof should be used in high-grade or high-grade waterproof material, making it level with the building standards to adapt. _ Shaanxi Huayin hotel roof garden landscape design concept of source (certified) _ hotel roof garden offers from Shaanxi View source landscape Engineering Limited.
