Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, water works, repair water and other projects, such as: large cracks leaking underground garages, tunnels, culverts, mine water leakage, all kinds of roof water trap engineering, 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 project so. water trap little common sense we understand Principle of water trap, then we look at the water trap of twenty-eight little common sense, although the content more streamlined, but we can refer to reference, as follows: 1. block rigid waterproof layer: to penetrate the waterproofing agent waterproof cement mortar to the bottom of the waterproof layer, an intermediate brick paving and other fast wood, then pouring cement mortar waterproof and wipe waterproof surface. 2. The backing material: sealing material embedded control to add depth, to prevent the sealing material and seams bottom bonding, deformable material is set in the middle bottom of the joint and sealing material. 3. impoundment Roof: build a certain height of water on the roof waterproof layer, heat insulation effect of the roof. The planted roof: the casing in the roofing layer or laying sawdust, vermiculite and other loose material, and grow plants, play a role in insulation in the roof. 5. The inverted roof: the hydrophobic insulation material is disposed on the roof waterproof layer. 6. waterproof layer and durable life: that of roofing layer can meet the deadline of normal use. Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, water works, repair water and other projects, such as: large cracks leaking underground garages, tunnels, culverts, mine water leakage, all kinds of roof water trap engineering, leaking toilet, water sealing, basement waterproofing plugging Nanchang water trap, has a wealth of experience in construction steel tile waterproofing preservative Nanchang water trap master, the ground water engineering, plant water trap works, roll roofing project so. cause facades may be several reasons for leak households used improperly, the process of renovation hammer hits the wall, causing shock facades hollowing, crack, resulting in water seepage. Caused due to uneven settlement of foundation, hot and cold changes and other reasons, resulting in wall cracks appear in varying degrees. This is the phenomenon of buildings after a certain time will appear. Exterior wall frame beams, columns and walls between the cracks. This is due to the construction, the tie bar spacing between the columns and the wall settings are not standardized. The gap between the window and the wall. In the process of masonry wall, the reservation in general than the sash of the window itself is slightly larger, so the installation will inevitably there are gaps around the window frames of various sizes exist. Exterior wall dividing joint or dividing joint set wrong, resulting in hollowing, destroyed the surface layer of waterproof paint is not set. Waterproof outer wall member projecting detail practice mishandled. Currently facades projecting wall lines, cantilevered plate member is gradually increasing, in various forms, bring to the construction operation difficulties, to wall waterproofing and security. The above is the cause of the external wall seepage, we should try to avoid damage to exterior walls, such as the occurrence of seepage water trap company, please find a professional trap. Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, water works, repair water and other projects, such as: large cracks leaking underground garages, tunnels, culverts, mine water leakage, all kinds of roof water trap Engineering Nanchang water trap works, 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 project so. Elevator shaft construction method of plugging the last chapter we have just finished analyzing the specific reasons for the occurrence of leakage of the elevator shaft, in this chapter we will continue this topic next to you on the construction method of plugging the elevator shaft. Elevator shaft plugging construction methods and other methods actually plugging leaks almost, we first start with the traditional method of plugging the water trap Nanchang factory, is directly cracks or leaks drilling, surface sealing, but the role is often less than ideal results, usually blocked on here, where they began to leak. Because water can not rule movement in concrete internal cracks, leaking from a relatively thin parts. Therefore, this method is now close to plugging eliminated, the market has been relatively less used. Currently finally welcomed an elevator shaft plugging construction method is chemical grouting, generally refers to the slurry produced by the chemical material, filling the mouth buried by drilling, the use of pressure writes structural cracks, allowed to relax, freezing, arrived waterproofing, sealing, reinforcement, reinforcement purposes. Commonly used to repair the deep cracks in concrete structures. The pressure and speed of filling can be divided into high and low pressure grouting method to slow rapid grouting method. At that time, in addition to the elevator shaft plugging applied outside the chemical grouting method has been widely used in various basement, bridge waterproofing works.
