External wall cracking treatment plan
1. The cracking of the external wall is likely to be caused by the bricks being not firmly built, which causes cracking problems. In such cases, the external wall often bends, and horizontal cracks are likely to occur in the middle of the bending position. At this time, we need to carry out reinforcement treatment, use the effect of high pressure to get the cement mortar into the cracked wall, and then build the column or use steel materials to fix it.
2. If a large area of ​​cracking problem is found on the outer wall, the base of the cracked wall surface needs to be chiseled into a U-shaped groove, but the groove distance is not less than 20 cm. After the base has been chiseled, it needs to be chiseled, and then hang the wire mesh. The next step is to thoroughly clean the surface of the external wall, and then lay anti-cracking materials, such as kraft paper, to take advantage of the special properties of the materials to ensure the quality of later construction.

Due to the fact that the strength is not very high, under the effect of natural temperature, the hot summer and cold winter baptism will make the external wall appear wet 〠Expansion and other problems, thus cracking occurs.
2. It may also be due to the imperfect construction process or the short interval of the construction stage, which leads to cracking of the external wall. For example, when the main body of the house is constructed, in order to hurry up, many construction personnel are eager to do the painting work. As a result, the whitewashed exterior walls are mixed with moisture, and under the action of high temperature, the whitewashed walls appear to be squeezed, resulting in cracking of the structure.
3. Sealing treatment is often required during the construction of external walls. If the material selection is not good, the sealing of the base layer of the wall will be lacking, which will cause cracking and shedding. Therefore, when performing sealing treatment, choose high-quality materials for construction, so that the wall is not prone to aging problems, and the construction base is effectively closed to form a protective film.
