What should I do if the outer wall of the house leaks?

Question 1: What should I do if the outer wall of the house leaks water? Answer: Never decorate the exterior wall to seep, or there will be endless troubles. The property management company has been dragging its feet and complaining to the relevant management departments. I don't agree with "water leakage is more like it." There's no way to fix it. "Look at the attitude of the property management company! What is the exterior wall decoration? Ordinary plastering brick? Mosaic? Dry hanging? . Ordinary plastering brick? Mosaic? Knock it out, remove the cracks and start over. When you get rid of the cracks, chisel off some brick joints, tick off the joints and cure the problem. Nothing can't be repaired. Waterproof paint doesn't work! Only treat the symptoms, not the root cause.

Question 2: What should I do if the external wall of the building leaks in? 1, the property is responsible for maintenance. You can use the maintenance fund. If it is a new commercial house, the developer is responsible for the warranty.

2. The developer is responsible for compensation during the warranty period. It has nothing to do with property. Not responsible for compensation outside the warranty period.

3. Generally, the seepage of external wall is mainly treated from the external wall, not the internal wall. You can find a waterproof and plugging company to do it for you and give you a warranty, which is better. The characteristics and construction practice of the materials used are relatively good. Internal wall treatment can't cure water seepage.

Question 3: how to deal with the water seepage from the outer wall of the building to the room? The causes of water leakage in the window sill of the external wall are complicated. It may be that water seeps into the roof or somewhere on the outer wall, then seeps down along the mortar layer of the wall and then seeps into the window sill. So the problem to be solved is to deal with it from the outside, but it is not easy to find the leakage point unless it is redone from the outside. The developer won't do this for you, unless the whole building leaks completely, it's basically inoperable! The rest are handled from the inside, which requires materials with good cohesiveness, durability, waterproofness and technology, so it will not be repaired generally!

Question 4: How to deal with the leakage of the external wall of the building? When dealing with the leakage of this kind of wall, the guiding ideology is to repair the cracks, hollowed-out layers and water seepage micropores on the surface of the mortar layer and restore the waterproof protection function of the cement mortar layer.

1, the hollow part of cement mortar layer should be chiseled, repaired and leveled with polymer cement mortar, and the polymer cement mortar should be plastered in layers, and the thickness shall be subject to the repair and leveling of the wall surface.

2. When the cracks on the wall are wide, the cracks should be wetted with water first, and inorganic waterproof plugging materials (impermeable and quick-drying cement, etc.). ) should be chosen to fill them. When the cracks on the wall are narrow, waterproof coatings such as polyurethane waterproof coatings should be used to brush the cracks, and the coating thickness can be controlled at 1.0 ~ 1.5 mm during brushing. The width of cracks should depend on whether inorganic waterproof and plugging materials can be filled. If they can be filled, they should be contained in wider cracks; If they cannot be filled, they should be contained in narrow cracks.

Question 5: What should I do about water seepage on the external wall of the house and how to solve it? Here, I will give you an analysis of the causes and treatment process of water seepage on the external wall of the house, hoping to be useful to you.

The seepage of external wall is mainly caused by cracks in brick joints and insufficient compactness of the wall. Let's see if it's raining first. If it's not raining and there is leakage, it may be that the upper floor is not waterproof enough, so leave it along the wall, so as long as it is waterproof. If it rains, it may be that the quality of tiles is too poor and the water absorption rate is too high. It is suggested that waterproof layer can be made on the inner wall. Anyway, there is no decoration at home. Just scrape putty after waterproofing. Or ceramic tile paste is not carefully used with cement mortar or empty drum. If you use waterproof latex paint and other materials with coating or color, it will affect the appearance. It is suggested that silicone exterior wall waterproofing agent be used for treatment. If there is a big crack, polymer cement waterproof coating should be used to repair the crack.

These are almost the reasons and remedies, and the trouble will be solved as soon as possible.

Question 6: The external wall of the house is leaking, how to fix it? First of all, you need to see if there are cracks in the outer wall. If there are cracks, water may seep out. Secondly, when it rains, look at the location of indoor roof seepage. If you get wet in the rain, it will reflect quickly, indicating that the waterproof layer is damaged. If the reflection is slow, it means that Gong is seeping into the room from the joint between the fence and the waterproof layer. Maintenance is simple, but remember to test the water or wait until it rains after maintenance. I believe it will be taken care of.

Question 7: How to deal with the leakage of the house and the external wall? I have encountered many such situations. Don't worry, here's a message. I'll know how to deal with it after reading it!

1 Many designers don't pay attention to detail design, such as slope of windowsill, olecranon, drip tank, through-wall pipe, embedded pipe fittings for external wall, door and window joints, curtain wall and wall, etc. Therefore, the design of these aspects is simplified.

For the sake of beauty, the external wall tiles (small apartment) are designed to be spliced with thin seams, so that the sealing material cannot be embedded between the tiles, resulting in water leakage.

The label of masonry and leveling mortar for non-load-bearing walls of high-rise buildings is generally lower than the design label for load-bearing walls. Although the strength can meet the design requirements, the water permeability is increased.

Architects do not attach importance to exterior wall waterproofing in design, and there is no waterproof concept and function setting in exterior wall facade design, which greatly reduces the functional coefficient of the building.

The interface connection of different materials is neglected in the design. For example, the exterior wall is designed with layers of decorative lines, and the elevation of the top of the line is the same as the standard height of the beam top. Because of the great difference between the wet expansion coefficient of the external wall brick and the concrete beam, cracks are easy to occur, which makes the upper part of the line seep. For the same reason, the root of the retaining wall is often prone to cracking and seepage.

External wall leakage has left hidden dangers for many residents and friends, so we should treat it correctly!

There are two possibilities for leakage. One is the construction joint. Due to earthquake leakage and slurry leakage, the concrete density at the eaves is not enough. If you don't want to take it off for waterproofing, the only way is to drill holes indoors for grouting (or waterproofing agent), and there is no money left to do this. If the cornice is not very high, it is safer to take it off for waterproofing.

Question 8: What should I do about water seepage on the outer wall of high-rise residential buildings? The method and effect are closely related to the structure of the wall. If possible, the fundamental solution is to redo waterproofing from the outside. If not, it can also be repaired from the inside, but it can only ensure that there is no water leakage indoors and nothing else. Provide free professional technical advice on repairing waterproof leakage of concrete, avoiding the troubles of repairing today, leaking tomorrow, repairing year after year and leaking year after year.

Question 9: The external wall of the house is leaking. No matter what your situation is, make the whole roof a cool roof system! After a sunny day, make sure there is no water on the roof and clean it up. High-pressure water gun cleaning, and then primer treatment. Do the leak first, use butter grade, and follow the instructions strictly. Then deal with the corner. When it's all finished, apply a medium coat. Then apply it to the surface. Three sprays will solve the problem.

If it is found that the wall is still wet, use our X4,24 to clean the external wall and expose the cement base. Spray X4 twice, and it won't leak for 24 hours. If you don't feel at ease, you can spray x4 twice on the interior wall.
