What are the causes of damp basement walls? What are the ways to deal with it?

Beijing Hongyu Changtai Construction Project ****.

Let me tell you that there are several reasons why the basement wall is damp:

The construction operation is not serious and not strictly followed.

Waterproofing layer. requirements, ignoring the overall continuity of the waterproofing layer.

Rigid waterproofing layer.

The thickness is uneven, and the wiping pressure is not dense or missing.

brick masonry. The compactness is not good, the masonry quality is poor, and the mortar is not full.

The quality of the waterproofing agent that wipes the rigid waterproof layer is unqualified, and the waterproof performance is not good.

The rigid waterproof layer is not fully cured after wiping, the mortar is dehydrated in the early stage, and the water evaporates prematurely, so that tiny pores are formed in the waterproof layer.

The treatment measures for damp basement walls are as follows:

Ring. Oxyritec.

Powder treatment method. Use the same amount.

Ethylenediamine. and acetone to make a half.

Ketoimide. Add epoxy resin and.

Dibutyl ester. In the mixture, the dosage is 16% of epoxy resin, and a certain amount of Lid powder is added, and it is painted on a clean and dry wall. If the wall has one.

Alkaline substances. It should be used first.

Sour water. Scrub, then rinse with water. Generally, it is painted twice, and the thickness is about about that.

Cyanide. Agent treatment method.

The mix is a prepolymer.

Carbamate.

49%, catalyst.

Triethanolamine. 1% thinner.

10% acetone, 40% cement. The operation method is to first pour the prepolymer into the container, dilute it with acetone, add triethanolamine, mix it into cyanide slurry, and finally add cement, stir evenly and then paint. If there is still slight seepage after painting, you can brush it again, and sprinkle a layer of dry cement surface after painting.

Calendering. Waterproof treasure. Dispose.

It can be used to mix various pigments to make the desired color, and apply it to the damp wall, which can not only prevent leakage, but also double as interior decoration.

Explain that the waterproofing of the wall by the foundation is good, which is caused by the temperature difference, because the temperature of the wall by the foundation is low, the indoor temperature is high, and the humidity in the air is to the low temperature of the wall, so the wall will cause the wall to be dry and wet, and the treatment can leave 100 seams outside the wall to build a wall, which solves the problem that the wall is not wet, and the dehumidifier is purchased.

1. Use moisture-proof materials

When decorating, it is necessary to pay attention to the moisture-proof problem of the basement, the wallpaper and vitrified bricks used in the basement will have a good moisture-proof effect, and the ceiling and wall of the basement should be waterproofed.

2. Pay attention to ventilation and moisture-proof

The basement itself is an area with poor air circulation, so under such conditions, we must pay attention to the ventilation of the basement, and strengthening air convection can reduce the moisture content in the room, which is also conducive to moisture prevention.

3. Add dehumidification equipment

In the south or in the rainy weather, the humidity of the outdoor air will be very high at this time, so it is useless to ventilate for a long time, so we have to add some equipment to artificially dehumidify. For example, add exhaust fans, air conditioners, or dehumidifiers and other equipment in the basement to dehumidify the room.

4. Dehumidification with desiccant

If the area of the basement is not very large, then put some desiccant or small items with dehumidification effect, such as desiccant and bamboo charcoal packets, you can put them in the basement, and you need to replace them frequently.

5. Floor heating and moisture-proof

In fact, floor heating is also one of the effective means of moisture-proof in the basement, floor heating can increase the temperature of the basement, and the indoor dry and not damp can be kept in a certain temperature range, so as to achieve the purpose of moisture-proof.

How to prevent moisture in the basement How to prevent moisture? Teach you the following good methods The basement is often warm in winter and cool in summer, and it is very comfortable to hide in it to escape the heat and cold, but there are some disadvantages, such as the basement is relatively easy to get wet, here I will share with you how to prevent moisture in the basement. Tools Raw Materials Desiccant Dehumidifier Step Method 1 The easiest way is to hang some adsorption desiccant in the basement, the most common is activated carbon carbon pack, you can also sprinkle some desiccant on some corners and ground that are more likely to be wet, you can break the mothballs and sprinkle them there with activated carbon powder to remove moisture, but the desiccant must be replaced every once in a while.

2 Since the main cause of dampness is ventilation problems, it is best to install ventilation equipment in the basement, and if possible, you can open a few skylights for ventilation. 3. Check whether there are cracks or damp spots on the basement wall or ground, if there are cracks and aging places that are easy to damp, it is best to shovel off the aging wall that is easy to mold and damp, and the area of the shovel is slightly wider than the aging area, and then brush the sealing paint again. 4 Don't put any plants in the basement, and you can put a dehumidifier in it, generally the basement is not too large, the effect of the dehumidifier is more obvious.

5. It is recommended to use some basement materials with good moisture-proof performance, such as laying a layer of tiles with good moisture-proof performance. You can try it according to the above method, and the effect is very good.

If the humidity is high, it is recommended that you use Dulux Sunny Paint special waterproof, you can use some waterproof mortar,

The cement wall is waterproofed, and the rest is as usual.

You can use mounting media, and the cement will fall apart, is it a problem with your material?

Do you know the texture wall mask, I suggest you check it out, that one might be better.

Many people will find that the basement wall has a reverse moisture phenomenon, which will affect the aesthetics, and it is important to deal with it in time. The first thing to do is to find the cause of its dampness, the phenomenon caused by different reasons, which needs to be treated differently, so that the results can be more satisfactoryHow to deal with the dampness of the basement wall?Let's take a look.

1. How to deal with the dampness of the basement wall.

1. Accelerate the air flow, and the ventilation equipment can be installed in a suitable position. Ventilation equipment can be divided into two types according to power. One is a non-electric extractor, which is a passive exhaust device.

The restriction can also be fitted with strong exhaust devices, such as negative pressure fans and axial fans, which may require an exhaust pipe. You can install an extractor with a window.

2. The desiccant can be hung indoors. Desiccants have a long shelf life and should usually be replaced frequently.

2. Basement wall decoration materials.

1. The wall stickers are very good. It is a label made of eco-friendly PVC material. The wall stickers are very resistant to moisture, unlike traditional hand-painted walls.

The pattern does not need to be painted separately because it is already designed and can be attached directly to the wall as long as the protective film is torn. Wall stickers in different sizes and colors can also be customized according to the home décor style. Wall stickers will not fall off for 5 years.

2. There are two main types of finished stone cladding stones: wood-based panels and natural stones, and marble is a more common natural cladding stone. The prefabricated terrazzo panels in artificial marble and wood-based panels are very decorative, making the interior more elegant and ornate.

3. Brush materialsThe brush materials mainly include large white paste, silver paste, lime paste, color paste, etc., and the first grade of the basement wall decoration materials here will be relatively low, because the decoration effect is not good, and it is not very durable.

4. Wall coverings used for basement wall decoration materials are usually fiberglass wall coverings and non-woven wall coverings. This type of wall decoration has a good decorative effect, but it is relatively poor in waterproofing and not easy to clean.

5. Glazed tiles are rich in color, color puzzles, white and color, printing colors and color murals. The glazed tile surface is very smooth, very clean, waterproof, and beautiful. Lined tiles can be used as tiles for living rooms and dining rooms, as well as walls for kitchens and bathrooms.

3. Precautions for basement decoration.

1. Moisture-proof is the first problem to be solved by Xiangjian in the renovation of the basement. Therefore, when decorating, it is necessary to choose materials with a better moisture-resistant effect. In general, the floor of the underground room can be made of glass bricks, the walls are covered with wallpaper and ceilings, and woodwork should be used as little as possible, as woodwork is prone to mildew.

2. Natural lighting is another problem that must be solved when the basement is renewed. The basement is not on the floor, and there is no way to use windows and doors for lighting, so you should choose a lamp with higher brightness. Also, you can use some mirrors to refract light, which increases the brightness of your basement.

If the basement is not carefully cared for, there will generally be poor ventilation, dampness and other problems, specific events are analyzed, then what are the causes of basement dampness, how to solve the basement dampness.

1. What are the reasons for the dampness in the basement?

1. There is a canal around the basement, although the canal is a certain distance from the basement, the water will penetrate into the basement through the basement, causing the basement wall to be damp and the ground to be damp.

2. The basement is too low-lying, due to the relatively low terrain, the rain will slowly erode the basement floor, especially in summer, when the rainy season comes, the basement will be more humid or even waterlogged.

3. The basement floor is not waterproof, due to poor waterproofing, the moist soil under the floor contains a lot of water, which will seep through the floor through osmosis, causing the basement to be damp, and the basement floor and wall should be waterproofed.

4. The basement is often closed and not breathable, if the basement is often uncleaned, managed, the windows are not opened, and it is often closed, resulting in poor air circulation and humid gas can not circulate, which will make the basement moldy and smelly.

5. Humid air enters. During the rainy season, heavy rainstorms, typhoon days, and other wet seasons, the air is very humid due to the increase in precipitation, and the humid air enters the basement and causes dampness.

Second, how to solve the dampness in the basement.

1. Ventilation and moisture-proof.

If the basement is damp, the simple way is to increase the indoor ventilation, just open the window for ventilation. If there is no window, you can turn on the electric fan to blow, which can also improve the dampness in the basement.

2. Dehumidification of electrical appliances.

If it is in the rainy season, the outdoor air humidity is relatively high, and the ventilation method cannot be used, so you can use a dehumidifier for dehumidification, or use it with an air conditioner, and the dehumidification effect is also good.

3. Dehumidifier dehumidification.

In addition to electrical appliances, you can also place some small items to remove moisture indoors, such as desiccant, charcoal packets, etc. However, the desiccant is not very effective, it is not used for a long time, and it needs to be replaced frequently.

4. Floor heating and moisture-proof.

Installing floor heating is one of the effective ways to prevent moisture in the basement, which can increase the temperature in the basement, evaporate the water, and reduce the air humidity. Keeping it at a certain temperature keeps the room dry and not damp.

The above is what are the causes of basement dampness, how to solve the basement dampness of all the content, Xi Xian Ran Kaiwang can help you understand the basement damp related knowledge, more decoration knowledge, decoration company evaluation, decoration cases, please continue to pay attention.
