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, but the top one should be rigid waterproof layer, waterproof layer roof flashing height should be 100 mm above the overflow rigid roof waterproof layer due to heat shrink swelling and deformation affected the structural floor, etc., 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, lay a floor mat or dry 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, 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. Whatever the factors causing leaks, people tend to blame the roof garden, which for the roof garden of the promotion have caused social resistance. Therefore, planning, design and construction units as well as the use of units should have sufficient knowledge. Jointly deal with waterproofing roof garden. 2 construction points and precautions 2.1 waterproof test and ensure good drainage system constructed roof garden, it must be a secondary water treatment. First, check the original Waterproof: closed outlet, then irrigation, for 96 hours (4 days and 4 nights) strictly closed water test. Closed water test, to carefully observe the leakage of the room, some houses closed water three days in a row does not leak, roof garden design, fourth genius began to leak. If it is guaranteed 96h no leakage, indicating good roofing effect. This waterproof effect, only apply to non-roof garden of the case. Waterproof layer is to ensure that the roof does not leak the key technical issues, but the roofing and drainage is one of the two aspects, roof garden design, you must also deal with the roof drainage system. Rooftop garden project, planting pool when the pool and road construction sites, shall comply with the original roof drainage system, roof garden design planning, planning and design, should not be blocked, isolated or drain and change the original slope. In particular, drains a large pool drainage layer under cultivation, to tie in with the roof drain, pay attention to the relevant standard deviation, so the sewer drainage layer under cultivation pool, to tie in with the roof drain, attention to the relevant elevation difference, so planting excess irrigation tanks can be smoothly discharged.
