Metal roofing plant waterproof roofing repairs have been the focus of the engineering industry, in order to avoid mistakes in the secondary repair waterproofing must do every step of construction. Isolation layer insulating layer is also called from the floor, floating building layers. Its role is to reduce the adhesion between the waterproof layer and the other levels of friction, so that deformation level is decreased or eliminated, requires the following parts of the specification to be set up in the new barrier. 1, should be set up between the rigid waterproof layer and grass-roots isolation layer to prevent or alleviate the structural layer deflection, foundation subsidence and deformation temperature and other factors lead to rigid waterproof layer cracking, causing roof leaks. 2, set the isolation layer of gravel between inverted roof insulation and a protective layer. In the inverted roof insulation, such as the use as a protective layer of gravel laid on insulation should Xianpu fabric, and then laying gravel. Puncture resistant fabric should be used, durability and corrosion resistance good material, laying should be paved, not open at the end. 3, should be provided between the rigid protective layer and waterproof layer barrier layer to prevent rigid protective layer of cement mortar, concrete and other fine aggregate expansion and contraction due to temperature deformation, the waterproof layer stretch squeeze caused by its being destroyed. 4, the building parapet gable roof structure is often caused by the expansion and contraction layers and crack. Therefore, between the structural layer and parapet gables reserve gap, to take out measures to avoid or reduce the occurrence of this phenomenon. For between flexible waterproof material, metal and rigid protective layer of waterproof material, should set the isolation layer between the rigid waterproof layer and the grass roots, in order to ensure the waterproof layer from damage. Waterproof layer is attached to the grassroots, grassroots quality is good or bad, will directly affect the quality of the waterproof layer of grassroots construction quality assurance and quality is the basis for the waterproof layer. Structural layer structure layer quality is extremely important to have a larger stiffness requirements, overall good, small deformation. Optimum use of the whole structure layer Slab, waterproof concrete slab, which is very good waterproof layer. If the structure layer using prefabricated panels, C20 fine aggregate concrete slab apply caulking dense, fine aggregate concrete admixture should also micro-expanders, when the slab width greater than 30mm or the narrow width must be configured within the slab structure tendons. When using waterproof coating layer, the upper slab remain top notch sealing material filling them. Before the protective layer protective layer construction debris should be cleaned on a waterproof layer, and waterproof layer strict quality inspection, conditional water test should be done in order to lay a protective layer after passing. Shenzhen fruit Seoul good waterproofing waterproofing undertake all types of buildings as a whole (roof, walls, pools, basements, etc.). Various types of trap, plugging works (roof, walls, toilet, sink, settlement, etc.) professionals to undertake all types of leaks difficult, with water plugging.
