How to deal with the leakage of basement exterior wall-the reason of basement leakage
A, how to deal with the basement wall leakage 1, surface method. It is suitable for dealing with the leakage of large-area structures. Under normal circumstances, the escape surface of the basement can not be carried out on the water surface, but only on the back of the water surface, so drainage should be carried out before construction to prevent the new waterproof surface from being eliminated by water under pressure. There are obvious holes and cracks in the basement, so water treatment should be carried out on the basis of treating the leaked holes and cracks. In the basement, when there is leakage on the surface of concrete structure, polymer cement can be suspended on the back with less pressure and slow water to spray water to form an impermeable cover on the surface to avoid filtration.
2. High pressure injection. This method can also be used to deal with water leakage in the basement. Injection holes may be provided in the structure, and these points may be organized into plums and triangles or then injected to form a flat shape inside the structure. Waterproof curtains. In addition, the method of "slurry sealing on the surface layer" can also be adopted from the bottom pipe, that is, the water is drained first, and then the surface is covered with waterproof cement mortar polymer in a large area. Once the resistance of the mortar meets the requirements, water will be sprayed from the water pipe to stop the water.
It is not difficult to repair the water leakage in the basement. Check the appearance of waterproof concrete carefully. First of all, look at whether the wall has beehives, holes, exposed tendons and conditions that affect the quality of the project. The filtered part is the vanishing point. If this work is finished, you can connect and waterproof it. At present, the commonly used materials are inorganic waterproof materials, such as waterproof materials, plugging agents and packaging seals.
Second, how to deal with the leakage of the basement wall-the reasons for the leakage of the basement Many projects have not taken waterproof measures, but only adopted simple implementation. In fact, measurement is very important. But the waterproof method and waterproof layer design are not high enough. Leakage often occurs in rainy season due to water accumulation in the upper layer. In addition, the gap is not handled well? This is one of the reasons for the water leakage in the basement. Some basements are waterproof with asphalt. Because of its high brittleness, low crack resistance, low low temperature flexibility and high water absorption, it is easy to cause waterproof failure and leakage.
The above is how to deal with the leakage of basement exterior wall and some reasons. I hope everyone can read it more so as to make full preparations for future implementation.
