How do the old roof garden waterproofing (1) Old building flat roof waterproofing flat roofs if the original construction is used in rigid waterproof practice, before rebuilding the roof garden, you should thoroughly check and repair surface cracks and split ointment. After the repair of the roofs of the best closed water test, the roof is filled with 100mm deep water drain after blocking Yan, until 24 hours after the check for leakage. (2) Old Building Flat roof drainage roof garden of all kinds of plant roots and leaves are easily clogged roof drains, so the roof garden of the sewer outfall should be increased and increased diameter. If you increase the diameter of the outlet and increase the difficulty, we should try to improve the outfall structure, so that it can quickly discharge roof water. The most important thing is to plant roots and leaves promptly clean up debris, Xi'an roof garden plant, it does not flow into the pipe. In the planting soil planting area must be placed drainage layer and a filter layer, Xi'an roof garden lighting, ventilation both to plant roots, but also play a filtering effect. Planting soil in the fine particles easily flow into the sewer, serious cases can clog water pipes, causing the roof water, become leaky roof problems. (3) properly handle garden ornaments and landscape architecture with the old roof slab structure links built roof garden, pillars and floor structure has a strong link, in order to prevent the roof wind landscape architecture and pieces blown, pillars and pieces of landscape architecture It must be fixed and firm, but also the need of embedded iron in the floor. Embedded parts must be through the roof waterproof layer exposed roof when wearing waterproof layer must ensure that there is proper construction practices. 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, 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 systems, planning and design, Xi'an roof garden casing, not blocking, drain and cut off or 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, Xi'an roof garden that drains pond drainage layer under cultivation, to tie in with the roof drain, attention to the relevant level poor, so that the pool of excess irrigation planting can be smoothly discharged.
