Question 1: How to dehumidify the basement if it is very humid? First of all, the basement is not a place for people to live, so the waterproofing and thermal insulation are not very good during construction. If you are renting in a basement: I suggest you buy an electric heater and an electric fan, and increase ventilation when raising the indoor temperature. This can remove indoor moisture. However, it only treats the symptoms but not the root cause. It is okay for a short period of time, but if you live in It won't be useful for a long time. If you buy a basement and it is your own home, just convert the basement into a place where people can live. Insulate all the walls in the room with 50mm thick benzene boards, use 20mm thick benzene boards on the walls, and use 20mm thick benzene boards on the windows. Use polypropylene cloth to waterproof the doorways and cold places, and there will be no problem.
Question 2: How to solve the problem of moisture in the basement. There are the following reasons for moisture in the basement:
1. Rainwater or melted snow penetrates into the soil and enters the basement through cracks in the foundation wall. This reason The most common, mostly seasonal occurrence.
2. The groundwater level is relatively high, and generally such houses are located in low-lying areas. Groundwater enters the room through cracks in concrete floors and walls, which also occurs seasonally.
3. The house is located on a spring at the foot of a mountain or in an underflow of groundwater, with the basement floor and foundation walls Even if intact, basements are often damp because they are constantly under phreatic pressure. This phenomenon occurs only occasionally and is extremely difficult to determine.
4. There are large cracks in the concrete floor or foundation wall, allowing moisture to seep into the soil.
5. Improper construction. There is no moisture-proof layer placed under the concrete floor or the moisture-proof layer is widely cracked. This situation is more difficult to judge.
6. The foundation drain pipe is blocked or broken, resulting in poor underground drainage, causing the water level to rise and seep into the basement along micro-cracks.
7. Artificial indoor humidification increases the relative humidity.
8. The water pipes in the basement or buried underground leak too much, and the sewer pipes are blocked or broken, causing the stagnant water to return to the ground.
9. The drainage system at the windows and exterior doors of the basement is not done well, causing rain or snow to enter the basement.
If there is no open water, the basement moisture problems caused by reasons 1, 4 and 5 can be solved by the following methods:
1. Drain water from the foundation wall of the house Slope, the slope is away from the wall and downward, extending 60 cm. The best material is concrete or asphalt concrete.
Secondly, bricks or stone slabs can be used. Here is the cheapest method, which is to compact the soil only within a distance of 1.5 meters around the house, with the slope facing outward. Be careful not to plant flowers and plants within this area. Some friends use this method to greatly improve the moisture in the basement. If downspouts drain rain or snow onto the ground, they should be extended 2 meters beyond the house. The above method is simple and easy to implement and does not cost a lot of money, but it can improve the moisture in the basement by 70%.
2. Apply 6 to 10 centimeters of waterproof mortar, lay wire mesh in the middle, and thicken the basement floor. Use waterproof glue to seal the gap where the floor and wall intersect. Use high-pressure expansion cement slurry to inspect and seal cracks in the wall, and cut the surface of the crack into a V-shape. This method is feasible and effective, but it costs more and reduces the height of the basement space.
3. Excavate along the exterior wall of the foundation. Apply waterproof mortar to the foundation wall to make exterior waterproof linoleum. If you want to do better, you can excavate the basement floor and redo the waterproof layer and floor. If this method is done well, it can completely solve the basement moisture problem. However, it is too expensive and takes a long time. Many people can't accept it.
If there is moisture problem in the basement caused by reasons 2 and 3, and there is open water on the basement floor, an underground water collection well can be used, and a submersible pump can be used to drain the water out of the house. However, it must be noted that the basic drain pipe should be led into the water collection well instead of draining into the municipal sewer pipe. This method can 100% solve the basement moisture problem. But it uses a lot of electricity, is sometimes noisy, and risks flooding into the basement when the power goes out or the submersible pump fails.
Home buyers are reminded that in some houses with water collection wells, the submersible pump pipes are buried in the soil and the water outlet is only placed in the grass. Some homeowners deliberately pile debris on the water collection well cover. When the pump does not work, It is often not easy to find when working, and you may regret buying such a house later.
Basement moisture problems caused by reasons 6 and 8 are the most difficult to diagnose and the least easy to solve. However, if you have the ability to find where the pipes are blocked or broken, it is not difficult to repair them.
It is easy to solve the problem of basement moisture caused by the ninth reason. Just add a roof over the basement windows and doors, and build brick walls to keep open water out of the door openings and window openings.
Question 3: What should I do if the basement is damp? Open the door frequently for ventilation. If possible, you can buy some charcoal and put it in the room. Or you can put some "indoor desiccant" sold in supermarkets in the room.
1. Use air conditioning to dehumidify. Most air conditioners now have this function. Activating the dehumidification function of the air conditioner can effectively solve the problem of room humidity during rainy periods, and can also provide comprehensive protection for TVs, computers and other "moisture-sensitive" home appliances.
2 When you are not using your computer or TV, it is best to make a protective cover to prevent the back of the appliance from contacting humid air. You can turn on more of these electrical appliances. The heat generated when the machine is running can effectively dissipate moisture. If the computer cannot light up due to moisture, you can turn it on and power it on. Generally, the monitor can display again in about 10 minutes.
3. If the outside air is too humid, remember to close the doors and windows; if the inside of the house is too humid, ensure that the room is well ventilated and use air conditioners and fans to dehumidify.
4. If the walls are covered with "sweat", it is recommended to purchase a dehumidifier for dehumidification.
5. In areas that are humid for a long time, you can use built-in charcoal in the room or spread bamboo charcoal under the floor of the Japanese style room. It has a good effect on balancing the room humidity, preventing dust, and purifying the air.
6. Do not keep anything indoors (flowers, birds, fish, insects, various pets...) especially fish and various plants (including cacti).
7. Put some quicklime (mixed with some sand) in a relatively humid dead corner.
Question 4: How to deal with air moisture in the basement 1. "Moisture" is caused by two aspects. 1. It is the "moisture" that penetrates into the room from the outside, which actually means water leakage; 2. It is caused by air condensation. The "tide" is manifested as uniform water droplets even in places where leakage is impossible.
2. The "tide" that penetrates into the room from the outside is caused by groundwater and surface water that seeps into the soil from rainwater. Except for the northwest loess and desert arid areas, basements may leak. In severe cases, it will show signs of leakage. Due to water leakage, there is also slight localized dampness. However, this phenomenon appears to be local or regional, and waterproofing and leakage plugging can be carried out indoors in a targeted manner.
3. The "tide" caused by air condensation is mainly caused by environmental conditions, related to air humidity, temperature difference, wind speed, air pressure, etc. It is common in the south, especially during the rainy season. This "moisture" can be solved by measures to prevent changing environmental conditions or mechanical dehumidification and ventilation.
If water leakage is ruled out, moisture return is a phenomenon of condensation. I guess what you mean by moisture-proofing is condensation.
1. Improve the temperature difference: increase the ground temperature (underfloor heating), or lower the air temperature (cold air conditioner dehumidification);
2. Reduce air humidity: close doors and windows in foggy weather , open the doors and windows (if you have windows) when the sun is hot at noon. Or close the doors and windows and use a dehumidifier; do not mop the floor with a wet mop.
3. Ventilation: Ventilation can take away moisture. Be careful not to ventilate on cloudy days, rainy days, or after heavy rains in summer, as it will bring a lot of moisture into the room.
Question 5: What to do if the basement is damp. Open the door frequently for ventilation. If possible, buy some charcoal and put it in the room.
Question 6: How to improve the humid living environment in the basement 1. Placing charcoal or quicklime indoors can effectively absorb moisture
2. Do not raise fish and other plants
3. Ventilation, but the ventilation in the basement is probably not very good. Are there any ventilation ducts?
4. Activate the dehumidification function of the air conditioner or buy a dehumidifier

Question 7: How to solve the problem of moisture in the basement? If the ground is dry and there are water droplets on the ceiling, it means that the waterproofing performance of the ceiling is poor and the ground moisture penetrates into the basement. There is an exception: the basement is humid and the temperature is high, and the outdoor temperature is much lower than the basement. At this time, condensation will occur on the top. Condensation is characterized by an even distribution of water droplets over the entire top. Water leakage is usually a local phenomenon, or water droplets first appear from a certain part.
Question 8: What should I do if the basement continues to be damp? What should I do if the basement continues to be damp?
First of all, we must determine the source of the moisture. Is there any water seepage in the outer wall? Is the mortar density of the cement on the ground too low? , and then do the corresponding treatment, such as painting the floor, laying floor tiles, waterproofing the walls, opening more windows or installing ventilation devices if possible. If you put valuables, you can buy a dehumidifier
Question 9: How to solve the problem of moisture in the basement? The basement is damp and has no ventilation. It is recommended to make diatom mud, which can regulate humidity and purify the air.
In addition, there is a company on the Internet that is very effective in preventing mold and moisture. Senran can solve this problem.
Thank you for adopting, I can help you
Question 10: How do you deal with moisture in the basement now? At present, almost all companies use the following three methods to deal with moisture: 1. A large number of water-resistant materials such as ceramic tiles, stones and so-called diatom mud are used in the basement, which will not be damaged even if there is water, but the basement is damp and cold; 2. High power A dehumidifier and constant temperature and humidity will only solve part of the moisture problem; 3. Use waterproofing to prevent moisture and provide psychological comfort.
Findley's patented moisture-proof technology is currently the most effective technology that can completely solve the problem of basement moisture. This technology solves moisture through two parts:
1. Polymer cement waterproof coating (JS waterproof) to solve the problem of outdoor moisture penetration.
2. Graphite polystyrene board internal insulation system (SEPS board), controls the temperature of the inner surface of the basement exterior wall above the dew point, ensures that no condensation water occurs on the wall, and regulates the indoor temperature in the basement and the temperature on the ground floor The temperature difference is within 1℃.
