How to determine the cause of such water seepage?

From the picture, it looks like a wall separating it from the outside. Well, there are several possibilities.

1. The defects of the wall façade lead to water seepage in the wall in rainy days, and gradually leak to the indoor wall. Due to the failure to dry in time, it caused a local humid environment, which breeds mold (black or blue-black spots, ringed cloth or dotted scattered), and the color difference is clearly visible along the damp parts.

2. Leakage of water pipes buried in the wall. In this case, if there is more than leakage, the water will continue to seep out, and the wall will be in much worse condition than in **.

The method of judging is also very simple, if it is water seepage on the exterior wall, then the humidity will increase after the rain, and there will be a gradual improvement after the sunny day. However, if the internal water pipe is leaking, the dampness will persist and the area will expand significantly over time.

If the wall is not an exterior wall, but is separated from other rooms, bathrooms, or kitchens, it can only be a leak in the wall. In this case, go to the other side of the wall to see if there are any water equipment, such as water heaters, that will be routed from a higher position.

Overall, considering the shape and number of wet spots, as well as the height of their presence, it was concluded that the possibility of water seepage on rainy days was the highest due to defective exterior walls.

From the ** point of view, it may be caused by water seepage on the exterior wall.

Observe the exterior walls, whether there are wet prints, whether the water from the air-conditioning drain pipe on the upper floor has been flowing to the exterior wall of your home for a long time, these will cause water seepage on the wall.

If you want to judge whether it is seeping water or anti-moisture, it is actually very simple, if it is water seepage, it will become very humid on a rainy day, and if it is anti-humid, then it is relatively humid on both rainy and sunny days.

Answer 1: We can roughly determine the cause of water leakage according to the location of the water leakage in the house, for example, there are water stains at the window sill, most of which are caused by the leakage of the window sill. The location of the leak is in the bathroom, which may be caused by the toilet waterproofing is not done well or the water pipe is leaking. Next, we investigate the causes of water leakage one by one and determine the leakage point.

For example, if you turn off the faucet in your home, if the water meter is still turning when there is no water, it means that the water pipe is leaking. 2. Water pipe leakage at home, we first find the water pipe construction drawings, and then listen to the leakage sound along the water pipe, the stronger the water leakage sound, the closer the location from the water leakage point. After identifying the leakage, we smashed the tiles and checked the cause of the leakage.

If the water pipe is damaged, you can replace the water pipe again or repair the water pipe by welding. 3. If there is only a watermark around the toilet leakage, then it may be caused by the toilet not being installed, we will remove the toilet, check whether the toilet has problems such as aging flange ring and unaligned drain outlets, and then reinstall the toilet. If the leakage of toilet pipes and toilets is eliminated one by one, then the leakage is mostly caused by the failure to do a good job of waterproofing the bathroom.

If the watermark is in the position of the pipe, it is mostly caused by leakage in the pipe gap, and we can re-seal the pipe gap. We also look at whether the waterproofing is not done well through the water storage test, and if there is a problem with the waterproofing, we have to redo the waterproofing.

Hello Question! My downstairs near the bathroom wall seepage, the wallpaper is damp, I think there is a problem with my home's waterproofing, but my home near the bathroom wall is also moldy and damp, downstairs did not live in when there is no mold problem, if the downstairs water pipe is going to the top will not seep, but also affected my home, downstairs did not decorate before my home did not mold damp.

When you decorate your bathroom, is the wall waterproof?

Asking questions is definitely done.

First, carefully observe whether there are water pipes around in a damp place, and if you don't think about whether the ground has been treated with moisture, if there is none, then it is a return of moisture.

The best thing to do is to use an electric drill to punch an eye in the wall, if it is leaking, then the inside will also be wet.

In life, when there is water seepage on the wall, or it becomes very wet, you must find the relevant cause. Let's talk about how to tell if there is water seepage or moisture return.

1. It can be judged by the surface.

When you find obvious marks on the wall, you can observe the dampness or touch it with your hands, if you touch the humidity on the surface of the wall, the other walls are very dry, this situation is water seepage.

Solution: Observe the place where the water seepage is connected to the wall to see if there is a water source, or it may be that the waterproof pants are not in place, and it may be the result of the rupture of the water pipe. Targeted waterproofing, or celebrations are to break the wall and find the cracks for repair.

2. It can be judged by the weather.

The temperature and natural changes brought about by different weather are also different, if there are traces of dampness on the wall during the rainy season, it is possible that rainwater penetrates the wall, causing water seepage on the wall.

Solution: After the rainy season, observe the corners of the wall, do waterproof construction for the corners, or brush the waterproof paint on the wall.

3. It can be judged by time.

Since it is found that there are traces of dampness on the wall, the maintenance will appear more blind, it is better to wait for 3 5 days to observe the changes on the wall, as time goes by, the changes on the wall will become more and more obvious, if in a few hours or 1 2 days, the damp traces on the wall are becoming more and more obvious, it means that it is a phenomenon of water seepage.

Solution: Find the root cause of water seepage in time, and repair the water seepage after the valve is closed.

4. It can be judged by temperature.

If it is in winter, especially in the case of a large difference in indoor temperature, it may cause the appearance of water vapor, especially in a room with dense tiles, it will be more obvious, so when water droplets appear on the wall, don't worry too much, this is a natural change, it belongs to the resurgence is also a normal state in Hu Xiang Hall, no need to do any treatment, don't worry about the hidden danger of water seepage.

Summary: The relevant content on how to judge water seepage or moisture return is introduced here, and you can judge whether it is water seepage or moisture return from the above aspects, and solve it according to the relevant reasons.

1. Dampness caused by condensation: This situation will generally get better in summer, but the mildew left behind still affects the appearance.

2. The wall is damp due to the leakage of the embedded water pipe: such a situation generally appears near the bathroom, or the top surface, or the wall, and there is generally a leakage in the joint part of the embedded water pipe. Late grip.

3. The wall is damp due to poor waterproofing of the ground: it also includes the wall and ground of the bathroom next door or the bathroom next door upstairs are not well waterproof, and once there is water in the bathroom, it will slowly penetrate.

There are four common causes of water seepage in interior walls:

1. There is no insulation layer.

The wall of some houses does not have an insulation layer, in winter, the temperature difference between indoor and outdoor is larger, so the wall is cold outside and hot inside, and the inner wall is high due to the high temperature, so the wall will form condensation, resulting in the wall being damp, and it is the whole wall, such a situation generally only appears in winter, and it will be good in summer, but the sequelae is that it will leave a lot of unsightly mildew, affecting the beauty of the wall.

2. Leakage of water pipes in the wall.

The dampness of the wall caused by the leakage of the embedded water pipe in the wall, generally this situation mostly appears near the bathroom, or the roof of the house, or the wall, and the embedded water pipe joint part has leakage, which includes whether the water pipe in the wall of your own home and upstairs is leaking, and the water seepage of the partition wall.

3. The waterproof measures are not good.

The wall leakage caused by the waterproofing project of the upstairs ground is not done, and the waterproofing of the upstairs ground is not done, and the ground waterproofing of the bathroom next door or the bathroom next door upstairs is not good, once the bathroom has water, it will slowly penetrate down.

The junction between the upstairs water pipe and the ground is not waterproofed, and it is very likely that there will be water seepage near the pipe, and the water will flow down the water pipe, resulting in water seepage on the roof.

4. Improper painting.

During the painting project, when painting the wall, the first wall paint is not dry, and the next wall paint is painted, and the water vapor in the wall fails to volatilize, resulting in the dampness of the wall.

Wall seepage treatment method:

1. Directly replace or repair the water pipe.

If it is the cause of the water pipe, you can replace the water pipe, or use the special adhesive tape for repairing the water pipe for temporary repair. The specific operation method is: first close the valve, cut off the water source, open the faucet to the appropriate position, to relieve most of the pressure in the water pipe, and then tie the leaking part with special tape, or seal it with ring gas resin adhesive.

2. Contact the property.

However, if it involves the external wall, it is best to report it to the property, and the property will contact the engineering department for maintenance.

3. Waterproof paint.

Owners who have leaks at home can buy leakage and waterproof paint, and paint the bathroom walls and floors by themselves, and the best way is to ask the decorator to solve it, which is more professional and effective. Or it's a little more troublesome, redo the waterproofing.

Look at the moisture on the wall, touch it out by people, or the mold on the wall is not the same as the normal wall color, and there is a place where water invades.

1. Dampness caused by condensation.

This situation usually gets better in the summer, but the mold left behind is still very unsightly.

2. The leakage of the embedded water pipe causes the wall to be damp.

This situation generally occurs near the bathroom, or on the top surface, or on the wall, and there is usually a leak in the embedded water pipe joint.

3. The wall is damp due to poor waterproofing on the ground.

The waterproofing of the upstairs floor is not done well, including the bathroom next door or the wall and ground of the upstairs bathroom itself is not waterproof, once there is water in the bathroom, it will slowly penetrate.

4. The junction between the water pipe and the ground is not waterproof.

If there is water seepage near the pipe, it is likely that the joint between the upstairs ground and the water pipe is not waterproof.

According to the situation you described, there is a high possibility of water seepage on the exterior wall, check whether the lower edge of the window is not well drained.

What's the reason for your house, I got a small piece wet in the top corner, half of the wall was wet, and next door was the bathroom.

In the quality inspection of construction projects, water leakage is the formation of water droplets or drips on the surface of only the components; Water seepage refers to the wetting or anti-alkali and diffuse spots (lines) on the surface of the component, also known as the urine wall.

You can complain to the local construction project quality supervision station, or apply for quality appraisal.

Most of the water leakage caused by decoration is caused by changing the layout of the house and drilling holes, and most of the water leakage in the building is caused by structural cracking and pipeline damage caused by external forces.

This is very easy to do, if the house is leaking, there is a glass of water in the leaky place, it will also be seen on the other side of the wall, if it is water seepage, the general water is less in the case of no traces of water dampness, unless there is a large amount of water for a long time, so that you can see the traces of wetness!

Look at the watermark, the leakage must be a bad pipe, if the water is not from the container that contains the water, directly to your house, this is not called leakage but seepage.

And usually the person who does real estate explains that water seepage is the water that enters your house from the outside world, not the water that comes out of your house, causing the furniture to rot and is responsible. See if you have checked in, if you have checked in, the property is responsible, if you have not checked in, you can only negotiate with the developer.

Leaking exterior walls of houses:

If it is within the warranty period (5 years), the property will notify the construction unit for repair.

For more than five years, the property can contact the maintenance unit for maintenance; Repairs can also be arranged by yourself.

If it is caused by the upstairs decoration, the upstairs shall be responsible for maintenance and compensation for losses according to law; If it is caused by a problem with the quality of the house, the developer will be responsible for repairing it and compensating for the loss.

House leakage solutions:

First, investigate the cause of the water leakage at the most serious location and analyze what the specific cause of the water leakage is.

1. Water leakage on the exterior wall. Then you have to find the property to solve the problem, because the exterior wall leakage is very troublesome to repair.

2. Bathroom, kitchen, balcony leakage, that is, waterproof is not done, then the ground tile or bathroom caisson is removed, re-leveling to do waterproofing, and then tiling, try to be careful when tiling, do not scrape off the waterproof layer, and it is necessary to pay attention to the waterproof interface position of the ground and the wall.

3. Water pipe leakage, then find out which location the water pipe is broken, find out the as-built drawings of your original hydropower laying, check the direction of the water pipe, and then check the location of the water leakage, remove the small range of floor tiles, and then repair the water pipe again, water pressure test, if there is no problem, then you can re-lay the bricks. (Note that it is best to have extra floor tiles, if it is not recommended to look at the bigger ones, otherwise it is difficult to repair one or two pieces).

In short, according to the actual cause of water leakage, whether it is because of waterproof problems or water pipe seepage problems, the specific problems are analyzed in detail, and then the repair plan is determined, do not do it blindly.
