Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, waterproofing, repair water and other projects, such as: large cracks leaking underground garage, tunnels, culverts, mine leaks, all kinds of roofing trap engineering, villas waterproof plugging leaking toilet, water sealing, basement waterproofing plugging, has a wealth of experience in construction steel tile water corrosion, ground water engineering, plant water trap works, roll roofing projects and so on. Deformation waterproof plugging need to stay laying overhead board, should mortar Calibrating, and sweep away any time on the roof waterproofing layer ash, debris, etc., in order to ensure clear overhead insulation layer airflow. Waterproof layer shall not prejudice the operation has been completed. Laying height laying overhead aerial thermal shield plate width or the height of the roof slope should change to determine the size of the pool water sealing, generally between 180 ~ 300mm adjusted. Overhead height is too low, heat insulation effect is not ideal; too high and not much ventilation effect trek, and the load increases, the overhead structural stability is not good. When the roof is wide, long distance air duct, hot air duct in circulation longer, resistance increases, it should use the higher overhead layer for ventilation. When the roof slope is small, the wind speed is also smaller, in order to facilitate the circulation of air in the duct, should be using more Gao overhead layer, whereas the choice of lower overhead layer. Overhead panels Overhead distance between the plate and the parapet and the distance between the adjacent parapet should not be less than 250mm. But should not be too wide to prevent degradation of insulation effect, and it is not too narrow, in order to prevent clogging and easy to clean up the debris. Setting Setting ventilation ducts overhead insulated roof ventilation ducts should be based on the maximum frequency of the local hot season winds (prevailing wind direction) trend, should be set up in the positive zone inlet, outlet set up in negative zone. When the roof is wider than 10m waterproof plugging, according to the plan need to stay Deformation. Overhead board laying should be smooth, An Jing, the gap is appropriate to cement mortar, mixed mortar filling them, according to the plan need to stay Deformation. Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, waterproofing, repair waterproofing exterior waterproofing plugging project, such as: large cracks leaking underground garage, tunnels, culverts, mine leaks, all kinds of roofing trap works, toilet leaks, water sealing, basement waterproofing plugging, has a wealth of experience in construction steel tile water corrosion, ground water engineering, plant water trap works, roll roofing projects so. Waterproof plugging cause poor quality houses, house husband waterproof plugging; senior residential water sealing, various underground pipeline water trap; hospitals, office buildings, government agencies, institutions building waterproof plugging. According to Property Condition divided: the new water seepage, plugging old house, old house trap and other matters. According to plugging into the situation: as waterproof plugging and renovation plus waterproof plugging. For stubborn performance can not be completely disposed of in general we recommend to completely dispose of the transformation reasonable doubt. Especially plugging: crack and all kinds of extra facilities underground construction, expansion joints, construction joints waterproof plugging. Some of the year due to the vast engineering investigation waterproofing, structural plan, construction quality and waterproof plugging skill mistakes, waterproof plugging poor quality reasons, substandard quality of the project. Some projects in the process of creating it failed, and even can not pass inspection. External surface water, groundwater and the structure of the internal structure of the wet etching, the structure to reduce air resistance long time, has not arrived in engineering structural waterproof needs. Therefore, waterproof plugging engineering quality inspection has become an important method before and after completion of the project. Each mortar concrete works Deformation, construction joints, structural cracks are called "new three seam", "new three seam" of leaking is all mortar joints concrete works of the most common drain, disposal methods same foundation, not the same local is carried to the disposal of the seam, the seam hewn wedge pump plugging conduct; with quick-setting caulking material, assuming little pressure, seepage flow is small, one-time the block, assuming hydrostatic large , water jet arrived, even when the high-pressure flow, the choice of law or buried pipe pumping method. Garage waterproof plugging waterproof plugging _ _ Jiangxi Shu family water trap provided by Nanchang Shu waterproof Engineering Limited. Nanchang Shu waterproof Engineering Limited (www.ncsrfs.com) strong, credible, in Nanchang, Jiangxi construction industry has accumulated a large number of loyal customers.
