What is the cause of water seepage in the walls? What went wrong during the renovation?

Nowadays, the technology to deal with wall leakage is relatively mature. Usually minor leaks can be solved by filling the seal. In severe cases, it is best to apply a waterproof layer to the inside and outside of the wall.

There are professional construction teams to choose from. No insulation layer: The walls of many old houses do not have an insulation layer, and the temperature difference between the surface and the inside is large in winter, and the wall is cold outside and hot inside, and the wall is easy to produce condensation, resulting in the wall being wet.

This condition usually only occurs in the winter, and in the summer it is fine. Because if it is a water leakage problem, in fact, the more serious the water leakage, the easier it is to find out the cause of the water leakage, in other words, the small water seepage is not easy to detect. If the exact cause of water seepage can not be determined, there is no way to repair the plastering layer, which is repaired in two or three times, and a certain amount of micro-expansion agent is mixed into the repair mortar to reduce the interface cracks of the old and new plastering layers.

Water seepage caused by water supply or drainage systems in <> rooms is also common, such as leaking water supply pipes or drain pipes. Because it is buried in the wall, once the water leakage occurs, the direct impact must be the wall decoration. Reason:

Generally, this kind of situation is next door to the bathroom or shower room, because the water is often used, and the shower is used, and at the same time there is no waterproofing or tiling, resulting in water often drenched on the wall to find out the reason If it involves neighboring relationships, try to communicate rationally about the ways and means of remediation, and do not engage in recklessness.

Scrape off the outer layer of the wall, if there are cracks, you can pot some cement, put a waterproof and moisture-proof sticker on the outside, and then repair the wall skin, which is as simple as mending clothes. This question cannot be said in one or two sentences. First of all, it is necessary to find the water source of water seepage and solve the water source, and the next step is to select the repair method in a targeted manner and treat the symptoms.

If it is water seepage in the bathroom or kitchen, it should be that the water pipe is not done well, find out the water seepage pipe, repair the test without water seepage, and then restore the previous state. It is the bathroom you carefully observe, often use water places, water is from the past, first look at the surrounding tile gap is not very large, if the gap is large, you should consider, the use of caulk, beauty sewing agent or plastic steel soil.

There may be cracks in the wall water seepage, or if the wall is not shaken well when pouring, it will cause cracks in the wall, and when decorating, pay attention to whether the waterproofing of the bay window and open-air balcony is hurt when slotting.

That is the problem of the waterproof link, that is, the decoration of the wall and the decoration of the ground, without some waterproof materials, if you do not use waterproof materials, it is easy to cause water seepage on the wall.

If it is water seepage on both sides of the window frame, usually caused by water accumulation in the gap at the top of the window frame, if there is water seepage near the pipe connected upstairs, it is likely that the combination of the ground and the water pipe upstairs is not waterproof well, and the water is left along the water pipe, if it is moldy on the wall, it may be that the wall is not dry during the decoration, and the water vapor fails to volatilize, resulting in the dampness and mildew of the wall.

1. There is no insulation layer, the wall of many houses has no insulation layer in the past, in winter, the temperature difference between indoor and outdoor is large, so the wall is cold and hot inside, and the inner wall is cold and hot inside, and the inner wall will form condensation due to the high temperature, 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, which will affect the beauty of the wall.

2. Leakage of water pipes in the wall, dampness of the wall caused by leakage of pre-embedded water pipes in the wall, generally such situations mostly appear near the bathroom, or the top surface of the house, or the wall, generally the pre-embedded water pipe joint part has leakage, which includes whether the water pipes in the wall of their own home and upstairs are leaking, and the water seepage of the partition wall.

If the wall seeps water for a long time, it will cause the wall to become moldy and cracked. It not only affects the normal life of the owners, but also has a certain negative impact on the spirit of the owners.

When the workers carry out the project, if the construction personnel are inexperienced, the level is limited or the construction period is not formal, the first wall paint will be brushed before the first wall paint is dry, the water vapor in the wall will be sealed and cannot be released, and the wall water seepage will occur, so the owner must look at the actual level and construction technology of the workers when selecting workers.

If the owner finds that the water seepage on the wall is caused by the water pipe problem, he can replace the water pipe in good condition by himself, or use the special adhesive tape for repairing the water pipe to carry out some temporary disposal. The specific operation method is: after closing the valve and cutting 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 adhesive tape, or seal it with ring gas resin adhesive.

The wall will be moldy, which may cause the wall to be soaked and rotten, and it will also affect the decoration of the wall, and it may also affect the waterproofing. Be sure to find the root of the problem, if the pipe is leaking, you must redo the pipe, if the waterproof is not done, you must re-lay the waterproof.

Once there is a problem of water seepage on the wall, the latex paint or wallpaper on the wall will be damaged first, if it is not dealt with in time, who may rise to the downstairs neighbor's house, if these problems occur, you should find a professional master to repair it in time.

In the process of home decoration, there will be many problems if the construction is improper, such as water seepage on the wall, if the wall is really seeping, how should we solve it? Today, let's analyze the specific causes of water seepage on the wall.

1. Humidity caused by condensation: In the past, some residential walls did not have thermal insulation. In the winter the inside of the inner wall is hot and cold, which can form condensation on the inner surface of the wall, causing the entire wall to become wet, and in the summer the situation is usually good, but the remaining mold can still affect the appearance.

2. Leaking water pipes embedded in the wall can cause the wall to get wet: This usually happens in the bathroom, near the upper surface or wall surface. Usually there is a leak in the connection of the recessed water pipe. This includes whether the walls of the house and the water pipes of the neighbors above them are leaking.

3. Poor waterproofing of the upper layer will cause the wall to become wet: The waterproofness of the upper layer is not good, even if the wall of the bathroom next door or the bathroom above is not waterproof. Once the bathroom is filled with water, it will quickly seep into the walls.

4. The connection between the water pipe and the upper floor is not waterproof: If there is a leak near the water pipe connecting your house to the upper floor, the connection between the floor and the upper floor is likely to leak. The water above is not waterproof enough, and water remains along the water pipes.

downwards cause water to seep into the ceiling.

5. The construction quality leads to the mold being molded in the decoration process: when the wall is painted during the decoration process, the first time the wall paint is not dried, and the second time the wall paint is started, the water vapor in the wall does not evaporate, causing the wall to become wet and moldy.

6. There is a problem with the waterproof layer. According to the relevant regulations, the bathroom and kitchen of the house delivered by the builder must have a waterproof layer, and in order to avoid the failure or damage of the waterproof layer, the water storage inspection should be carried out on the bathroom and floor. decoration of the kitchen during the period.

At present, the waterproof material commonly used in home decoration is acrylic waterproof coating, which belongs to the waterproof material of the coating film.

The reason for water seepage on the wall may be that the wall is too wet, and the whole wall is just renovated, and there is no timely drying treatment, which is likely to cause water seepage from the wall.

Because when decorating the house, the walls are not waterproofed, and it may be because the walls are too wet, so they will seep water.

It may be that the waterproofing of the house is not done well. If there is a problem with the quality of the house, it will cause water seepage on the wall of the renovated house, and you should find a property.

It shows that the workmanship is particularly not up to standard, and the materials are particularly bad, so there will be water seepage, and you should look for property at this time.

Home renovation waterproofing is very important, but it is also a link that is prone to hidden dangers. For the decoration of Xiaobai, it is easy to find us in this link! ImpactReasons for water seepage on the decoration wallWhat is the problem and how to deal with it?

Reasons for water seepage on the decoration wallThere are several factors that can cause water leaks in the walls to be really harmful. Not only will it affect the construction of your house, but it will also cause inconvenience to your life. As for the cause of the water leakage in the wall, there are several possibilities:

The decoration of the wall contains the cause of water seepage1. The wall is not insulated.

If there is no insulation on the wall, then in winter, due to the large temperature difference between the inside and outside, the outside of the wall is cold, and the internal temperature is too high. If the temperature of the inner wall Sakura is too high, condensation will form on the walls, which will make the walls moist. Water leaks on the wall.

Reasons for water seepage on the decoration wall2. The problem of water pipes in the interior wall.

If the water pipes are not properly connected, or if poor quality water pipes are used, it can cause water pipe leaks, including ridges or leaking or seepage from partition walls. This usually happens near the bathroom, on the ceiling or on the wall.

Reasons for water seepage on the decoration wall3. The waterproof measurement is not good.

This waterproofing measure is not enough, not only for the home, but also for the wall of the neighboring bathroom, the waterproofing of the floor of the adjacent bathroom on the top floor, and the waterproofing of the connection between the upper water pipe and the floor. If done well, the roof or walls are not waterproofed well and may cause leaks.

Reasons for water seepage on the decoration wall4. Improper treatment of the wall during the construction process.

It's to look at the decorators, coveted for speed, the first time the paint did not dry, painted on the wall, inside the steam wall does not evaporate. Make the walls moist and moldy.

Once the walls see water seepage, it's imperative to act! Once you notice a leak in the walls of your house, the first thing you should do is to find the cause of the leak. This is the most basic.

1. If there is no leakage in the insulation on the wall, then, no doubt, find the problem and let them take care of the repair.

2. If the wall of the water pipe is broken, there is no way to replace or repair the water pipe. Remember to repair the water pipes with the selected tape. I don't recommend that you fix it yourself, or get a professional to fix it.

3. The impermeability has not been completed, so it can only be made waterproof again, and the best way to brush the bathroom walls and floors by yourself is to ask the decoration worker to be responsible, so it is more professional, more useful or waterproof.

In the decoration process, it is inevitable that there will be all kinds of problems, the wall construction is complex and cumbersome, if a certain link of construction is not done, the wall may appear peeling, water seepage, etc., some owners ask what are the reasons for the water seepage on the wall of the newly renovated house, and what to do about the water seepage on the wall on the baseboard. We'll take a closer look at it right away.

What are the causes of water seepage on the walls of newly renovated houses?

1.The problem of the construction of the wall itself. This mainly refers to the masonry mortar of the wall masonry is not full, which leads to a lot of empty joints in the wall, which also involves a very professional problem, that is, there will be a capillary channel to form a siphon.

The material of the upholstery surface is soft, and the moisture in the capillaries is easily dissipated. In addition, because the thickness of the plaster is uneven, these can cause water seepage into the wall.

2.Problems with the connection between doors and windows and walls. If at the beginning of construction, there is no olecranon and drip line, then the indoor sills will be lower than the outdoor sills, and the outdoor sills will not be set up with a downhill slope, so that the water will pour in, so that the wall will seepage.

3.Improper handling of hole blockages.

After understanding the main causes of wall water seepage, let's take a look at the treatment methods of wall water seepage.

What to do if the wall above the baseboard seeps water

1.Since there is a water seepage problem in the wall, if you want to fix it, the first thing to do is to find the water seepage point of the wall, see if there are cracks, and then follow the cracks found to remove the external wall plastering layer at the interface between the masonry and the structural beam. When processing, it is also necessary to pay attention to prevent new hollow drums due to improper operation of the bridge god.

2.After the above treatment, the base layer is cleaned and reinforced with the help of steel wire mesh to prevent cracking again.

3.Repair the plastering layer. The plastering layer is a key point of the entire waterproofing repair process, and this process cannot be completed overnight, and generally needs to be repaired in two or three times. The main use of this step is the expansion agent, but the dosage must be strictly controlled.

4.Paint the exterior wall and apply a waterproof coating after drying.

What are the reasons for water seepage on the wall of the newly renovated house, and what to do about the water seepage on the wall on the baseboard, the article has been sorted out in detail for you. If you can't repair it, it is recommended to ask a professional to come to deal with it.

Oooh oh.

Water seepage on the wall of the interior decoration of the house is a relatively common problem, especially in the wet season, the problem is more obvious. Water seepage on the wall not only affects the appearance, but also damages the structure and service life of the wall, and in serious cases, it will also affect the living safety of the family. So, what are the causes of water seepage on the wall?

1.Exterior wall water seepageExterior wall water seepage is one of the main causes of indoor wall water seepage. For example, rainwater can enter the walls through cracks, crevices, leaky pipes, and drainage systems in the exterior walls, causing water seepage.

2.The pipe connection inside the house where the leaking pipe is located and the pipe itself are damaged or aged, so that the water inside the pipe leaks into the wall, resulting in water seepage on the indoor wall.

3.Building quality: Poor building materials and construction quality, such as no plaster on the wall or poor quality of mortar, or excessive cement water addition causing wall cracks, or poor waterproofing projects in the sanitary and only destruction room, etc., will lead to water seepage on the indoor wall.

4.Indoor dampness, such as not ventilating the room for a long time, or bathing, drying clothes, etc., will increase the indoor humidity, these conditions will promote water seepage on the wall, especially when the season is humid.

5.The above factors of neurasthenia are not the same as neurasthenia, which will make the originally normal wall, because of the influence of artificial psychological effects, produce the illusion of water seepage on the wall.

The above are the main causes of water seepage on indoor walls. In the face of the problem of water seepage on the wall, we should grasp the problem and take timely measures. For the situation of water seepage on the external wall, we can take some measures to deal with it, such as mending the leakage, strengthening the waterproofing, etc., and repairing the pipeline in time for the leakage of the internal pipeline; In addition, it is also necessary to do a good job of ventilation and keep the room dry.
