Waterproof construction process which hair removal process to clean the grassroots handle key positions many times when the underlying brushing brushing waterproof layer membrane bonding requirements ⒈ grassroots grassroots compacted surface should be smooth, using cement mortar layer, must be fully curing, not a crisp, sand, from the skin phenomenon, should meet the design requirements. ⒉ old surface must be clean, without debris and dust, so as not to affect the bond strength. ⒊ concrete surface moisture content should not exceed 10% of the grass-roots ⒋ brushing waterproof coating should be dry. Generally empirically, visually, can also be 1m square plastics, cloth cover on it, after the use of sunlight for 1-3 hours (also available hair dryer heating method) and watch whether soda, soda can be considered if no dry before construction. 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 plugging caisson, mine leaks, each 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. facades may cause Some reasons for households would leak improper use, the renovation process hammer hits the wall, causing vibration hollowing facades, waterproof plugging cracks, causing water seepage. Caused due to uneven ground subsidence, hot and cold changes and other reasons, resulting in cracks in the walls appear to varying degrees. This is the phenomenon of the building after a certain time appeared inevitable. Exterior wall frame beams, columns and walls between the cracks. This is due to the construction, the tie bar spacing between columns and walls are not set norms. The gap between the window and the wall. In the course of masonry walls, window frames than the general reserve itself is slightly larger, so when you install a window sash around the gap is bound to have different sizes exist. Exterior wall dividing joint or sub-lattice seam settings wrong, resulting in hollowing, destroyed the surface layer of waterproof paint is not set. Waterproof outer wall member projecting detail improper handling practices. Currently protruding wall facades lines, cantilevered plate member is gradually increasing, in various forms, to bring difficulty plugging construction operations, poses a potential threat to the wall waterproofing. The above is the cause of the external walls of water seepage, and we should try to avoid damage to exterior walls, such as the occurrence of seepage water trap company, please find a professional trap.
