Whatever the factors causing leaks, people tend to blame the roof garden, roof garden design, which caused the roof garden of the promotion of 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, the 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, it must also deal with a good 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 engineering, 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, roof garden design specifications, 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 that the pool of excess irrigation planting can be smoothly discharged. Leaking roof garden roof garden construction is one of the biggest problems affecting quality of the project and the results, as the main reason causing leaking roof garden. (2) the height of the construction of waterproof material waterproof material enough height in the construction should and performance, quality and use of functional coordination with the surrounding buildings, to meet the water requirements of the building. If the height is mainly the waterproof layer construction legacy left to absorb moisture and moisture in the air, roof garden design team, after wind and sun, accelerate the aging waterproof layer, waterproof layer cause damage. (3) the construction of the roof garden waterproof layer structure is destroyed during the construction of the waterproof layer construction, the construction unit of the construction quality consciousness is not strong, waterproof material the use of substandard quality control, will reduce the life of waterproof layer, waterproof layer construction time also susceptible to damage.
