In the decoration of the house, there are many reasons for the water seepage of the outer wall. Mistakes in design, improper selection of materials, irregular construction techniques, inconspicuous detailing, and improper secondary decoration may cause the outer wall to seep. If the water seepage is serious, the wall decoration will bulge and fall off, which will affect the aesthetics of the building and sometimes cause damage to the property and cause people's property to suffer losses. The following is a small series of decoration home network to let everyone know how to do the water seepage of the outer wall of the house ? The method of water seepage treatment on the outer wall of the house and the precautions for seepage in the outer wall.
How to do water seepage in the outer wall of the house?
The first thing to do when discovering the water seepage of the exterior wall of the house is to find the reason for the water seepage. This can be analyzed from the materials selected for the building. Therefore, many modern houses are made of ordinary concrete porous brick materials, and after investigation in recent years, It has been found that almost all of the external walls of ordinary concrete perforated brick materials have cracks and water seepage.
House exterior wall seepage treatment method 1
After finding the cause of water seepage of the external wall, certain measures can be taken for it. For this type of external wall seepage, the main layer is to repair the mortar layer of the outer wall, the surface crack, the empty drum layer and the water seepage micropores. To restore the waterproof protection function of the cement mortar layer. The specific method is to remove the hollow portion of the cement mortar layer, and then repair and level with the polymer cement mortar, wherein the polymer and cement mortar should be layered and pressed, and the thickness is used to flatten the wall surface to the standard.
House exterior wall seepage treatment method 2
In the water seepage of the external wall, if the gap on the surface of the wall is wider, the water should be sprinkled to wet the gap, and then the inorganic waterproof plugging material should be used to fill the gap. If the gap is narrow, polyurethane waterproof coating can be used. Brush the gap, the thickness should be controlled between 1-1.5 mm during the brushing process, and for the width and narrowness of the gap, it can be filled with inorganic waterproof plugging material as standard. If it can be filled in, it belongs to the comparison. A wide gap, if not, is a narrow gap.
Precautions for seepage in external walls:
Reasons for leakage of high-rise building exterior wall
1. The crack of the wall itself
(1) Due to the fact that the concrete is not vibrated during the pouring of the shear wall concrete, the solidity of the concrete body is insufficient, and a leak path is formed.
(2) Due to the construction technology of wall and plate simultaneous pouring, there is not enough solid time for the concrete of the wall, which leads to the wall sinking and insufficient solid cracks.
(3) In the maintenance of concrete, only pay attention to the watering and maintenance of the concrete wall, and the maintenance of the external wall is not enough, especially in the hot summer, the temperature difference between the inside and outside of the wall will be large and cracks will occur; secondly, the maintenance of the wall will continue. Not enough time, causing shrinkage cracks in the concrete.
2. Cracks in the plastering layer on the outer wall
For high-rise buildings, due to the difficulty in precise control of the verticality during structural construction, the thickness of the screed in the outer wall is too large, which is easy to crack and increases the possibility of water leakage.
3. Cracks in the masonry bricks
During the masonry, due to the poor workability of the vertical head joint mortar, the shrinkage is large, the strength is low, and it is not dense; the masonry wall is not fully wetted in advance according to the construction regulations; the improper temperature is built and the wind load swinging factor Under the influence of the mortar, the mortar shrinks and cracks, creating a gap.
4. Improper handling of various holes left in the construction of the external wall
The template wall-to-wall screw hole left in the external wall construction, the reserved hole in the cantilevered scaffold reserved, and the hole left in the steel pipe scaffold, especially the hole in the shear wall (for the tie rod) ), when it is blocked, it is not dense and creates a gap.
5, improper installation of external wall sash
During the installation process of the outer wall sash, the window frame is not securely installed, the pipe connection in the combination window is not standardized, the rubber seam around the window frame is not tight, the window sill is not filled with water, and the window frame is surrounded by the streaking window frame. As a result, the seam around the window frame is not tight, causing leakage.
The above content is how to do the water seepage of the outer wall of the house brought to you by this small series? The introduction of the water seepage treatment method and precautions for the exterior wall of the house is for your reference. I hope to provide some help to the friends who are seeping the exterior wall of the renovated house.

Diamond Sharpening Stones is a Abrasive Honing Stones have man made diamonds bonded to a hard, rustles surface which provides an abrasive surface that is harder than any other material - Diamond Stones are very sharp and capable of lasting almost indefinitely. Use Diamond Stones to sharpen or lap almost anything, from tool steel to carbides to glass and ceramics (including ceramic stones). Whenever practical, wetting the stones with water or light oil will virtually eliminate clogging while you sharpen,but they can be used dry as well.
One of the most common arguments for using diamond sharpening plates is that they are flat and do not become hollowed out during their working lives. The first point is only partly true, as the flatness of the plates depends a great deal on the quality of, and the method used to manufacture the plate. But it is true that they do not become hollow in use, like other kinds of sharpening stones do.
