Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, water projects, and other projects to repair water waterproof plugging quotes, such as: large cracks leaking underground garage, tunnels, culverts, mine leaks, each kinds of roofing trap works, toilet leaks, water sealing, basement waterproofing plugging new waterproof plugging, has a wealth of experience in construction steel tile water corrosion, ground water engineering, plant water trap works, roll roofing projects so. 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, 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, 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 water and other projects, such as: large cracks leaking underground garage, tunnels, culverts, mine leaks, all kinds of roofing trap engineering, toilet leaks, high pressure grouting waterproof plugging waterproof plugging, plugging basement waterproofing, has a wealth of experience in construction steel tile water corrosion, ground water engineering, plant water trap works, roll roofing projects and so on. water trap how water trap do general practice in the living room renovation process, the need to make room for water main bathroom, kitchen and balcony. The main purpose is to waterproof their own families in the use of water, will affect the downstairs neighbor through leakage. So when his home roof leaks or seepage in their waterproof roof is useless, you must have a waterproof effect in your neighbor's upstairs floor. While living in the first floor of the users do not have waterproof plugging waterproof, but water can also play a moisture barrier, moisture barrier and so on. Waterproof general practice is: In the original ground with cement mortar, to be dry (not damp finger), in combination with a double into the polyurethane waterproof coating evenly brush three times or asphalt or fiberglass cloth made of two oil-cloth processing . Requirements bathroom wall do 1.2-1.5m high, not less than 0.5m tall kitchen, balcony with exterior wall sill height prevail. After drying off water storage to do 24 hours a closed experiment, confirming that no leakage after ground construction. If the floor or wall of the original room was destroyed, it must be waterproof and sealed closed water experiments.
