Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, waterproofing, repair water and other water projects plugging slipping through the net, such as: large cracks leaking underground garage, tunnels, culverts, water leakage plugging mine drain, all kinds of roofing trap works, toilet leaks, water sealing, basement waterproofing plugging, waterproof anti-corrosion steel tile, ground water engineering, plant engineering villa water trap water sealing, waterproofing membrane roofing and so has a wealth of construction experience. 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 wider, longer distances external waterproof duct sealing, hot air duct in circulation longer, increase the resistance, it is advised to use a 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, 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. Basement waterproofing plugging selection requirements for basement waterproofing plugging project selection that is quite important, Here I will introduce one kind of basement waterproofing material. We first look at the main features of this product, and then we'll look at this product is made from what materials research. This product has a waterproof seal seam sealing elastic material, when plugging the pool sided seam side when the distance increased beyond the elastic recovery rate flexible waterproof material, since the material has a water swell characteristics, material Within the program can still start and end the effect of water swelling, swollen body still has a rubber nature, more water, acid and alkali. Because this product a strong and effective water effects, is widely used in construction joints underground railway, tunnel and engineering, flexible joints, cracks. A good product must be made good to the selection made for the preparation of production, is the choice of this magical product has excellent resistance to ozone aging primary function of EPDM material, supplemented butyl rubber, natural rubber and black, curing agents a variety of materials, the mixing, rolling, curing and other advanced technology to prepare waterproofing membrane. So that it not only has a high tensile strength, but also together with excellent elongation, spring rate and low temperature function, but it has a particularly excellent resistance to ozone aging function is unrivaled by other waterproof membrane, The experiment proved that the service life of up to five years or more. Pool water sealing, water trap Shu good cheap (certified), Nanchang Nanchang waterproof plugging by Shu waterproof Engineering Limited. Nanchang Shu waterproof Engineering Limited (www.ncsrfs.com) is a leader in Nanchang, Jiangxi, construction, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
