What should I do if the underground garage is too wet? What to do if the garage is wet, how to solve

Ways to solve the problem of dampness in the garage:

1. The decoration focuses on moisture-proof construction.

If it is in the period before the renovation, it is necessary to focus on the moisture-proof construction of the underground garage. In the early stage of decoration, we should focus on the moisture-proof construction of the ground and wall to form the waterproof layer of the underground garage. As long as the method is right and the construction meets the specifications, the underground garage can maintain the right humidity and will not be damp.

2. Manual intervention in the use of dehumidifiers.

The dampness of the underground garage that occurs during the later use process requires human intervention, and one of the intervention methods is to use a dehumidifier. The equipment of the dehumidifier should be determined according to the usable area of the underground garage to ensure that the dehumidification efficiency of the dehumidifier can be played normally.

3. Strengthen ventilation to reduce humidity.

At the same time, it is necessary to use the entrance and exit passages of the underground garage to strengthen ventilation, so as to reduce the humidity of the underground garage. Ventilation can make use of the natural ventilation brought by the building design structure, or manual intervention can be carried out to strengthen ventilation and ventilation, so that the humidity of the underground garage can be balanced with the external environment as much as possible.

3. Strengthen ventilation to reduce humidity.

At the same time, it is necessary to use the entrance and exit passages of the underground garage to strengthen ventilation, so as to reduce the humidity of the underground garage. Ventilation can make use of the natural ventilation brought by the building design structure, or manual intervention can be carried out to strengthen ventilation and ventilation, so that the humidity of the underground garage can be balanced with the external environment as much as possible.

1.If the humidity is not very severe, desiccant can be used appropriately.

2.Improve the temperature difference to prevent moisture: use geothermal heat to increase the ground temperature of the underground garage, thereby promoting the evaporation of air humidity in the underground garage, so as to improve the humidity in the garage.

3.According to the calculation of the garage area, add the appropriate power dehumidification equipment to the underground garage for moisture removal.

4.The construction of moisture-proof measures in the underground garage to form a waterproof layer can avoid the occurrence of moisture.

5.The use of building structure to form natural ventilation or manual intervention to ensure a good ventilation environment in the underground garage can also effectively avoid moisture.

The first thing you need to do is to keep the underground garage out of moisture. Only then can the moisture in the room be completely removed. The general method is to use a high-efficiency composite waterproofing agent to scrape and coat the moisture-proof layer after 5 mm on the wall and ground of the underground garage.

Then use woven bags to pack several generations of white ash for moisture absorption. When the white ash is saturated, it is exposed to the sun to remove the moisture. In getting the damp suck in the ground.

This way several round trips will suck the moisture out of the garage. It is a more economical approach.

1.Intermittent ventilation: The best time to do this is to close south- or southeast-facing windows and doors on rainy days to reduce moisture entering the room.

At noon, the air humidity outside is at the highest value, and it is not appropriate to open the window, so it should be opened in the afternoon or evening, when the climate is relatively dry, open the window to adjust the indoor air.

2.Lime moisture absorption: On rainy days, quicklime can be wrapped in cloth or sacks and placed in various places indoors to keep the indoor air dry.

Air conditioner dehumidification: It is simpler than the previous two methods, but it consumes electricity, so it is recommended to use other environmentally friendly and moisture-proof methods to save energy.

Practical moisture-proof gadgets.

3.Moisture Absorbent Box: A must-have for wardrobe dehumidification.

The more common hygroscopic products on the market are generally made of calcium chloride granules as the main content, and most of them also add flavor ingredients, so they integrate functions such as dehumidification, aromatherapy, mildew resistance, and deodorization. Moisture absorber boxes are mostly used for moisture absorption in wardrobes and shoe cabinets. To use it, simply put it in the cabinet.

4.Moisture Absorbent Packs: Best in confined spaces.

The principle of the hygroscopic bag is similar to that of the humidity absorbent box, but the contents are mainly water-absorbing resin, and after absorbing water, it becomes jelly-like and is not easy to disperse into pieces. In addition to clothing, leather goods, stamps, cameras, pianos, computers, audio-visuals, etc. can be used to help dehumidify. If placed in a confined space, the moisture absorption effect is better.

The dampness of the underground garage has a great impact on the car, mainly including the following adverse effects:

1. If you park in the underground parking lot for a long time, especially in rainy days, the car is more likely to be damp and moldy, which is easy to breed various germs and affect the health of the people in the car.

2. If the car is in a humid place for a long time, it will affect the parts and lines. Especially in the engine of a car, moisture can easily cause aging circuits and rust of parts, which can damage the engine.

3. In a humid environment, the speed of metal oxidation will be accelerated, and the failure rate of parts will increase. Parking the car for a long time will also be greatly affected, and the tires are prone to moisture aging, which is undoubtedly an extremely dangerous hidden danger.

If the underground garage is wet, it is recommended not to park for a long time. The hazards of a damp underground garage to a car are as follows:

1. Car audio:

If the environment is too humid, it will be difficult to read CDs, especially the chips in car stereos. In a humid environment, these chips can become very fragile, leading to deterioration of the sound.

2. Car spare tire:

Since the spare tire of the car is generally placed in the corner in order to save space, and it is easy to hide some dust, if the underground garage is in a cold and damp environment for a long time, it may cause mold in these places. corners, which in turn corrode spare tires and tire changing tools.

3. Others: In addition, the humid environment of the underground garage may also lead to various minor faults of the car.

1. Do a good job of moisture-proof decoration.

In the early stage of decoration, focus on the moisture-proof work of the ground and wall to form a waterproof layer of the underground garage. As long as the method is correct and the construction is in accordance with the specifications, the underground garage can maintain the right humidity and will not get wet.

2. Use a dehumidifier.

If the underground garage gets wet, manual intervention with a dehumidifier is required. The equipment of the dehumidifier should be determined according to the usable area of the underground garage to ensure that the dehumidification efficiency of the dehumidifier can be played normally.

3. Strengthen ventilation.

Increase ventilation to reduce humidity in the underground garage. Ventilation can use the natural ventilation brought by the building design structure, or it can be manually intervened to strengthen the ventilation, so that the humidity of the underground garage is balanced with the external environment.

4. A water guide can be installed for drainage.

If the dampness of the underground garage is caused by groundwater, it is necessary to install a gutter-type sewer in time to fully drain the groundwater to improve the dampness of the underground garage.

5. Use desiccant in time.

For example, in the season when the humidity is not very serious, it can be used with desiccant to achieve the purpose of keeping the underground garage dry and hygienic.

Utilize insulation boards or insulation mortars.

The general practice is to buy the most expensive dehumidification system, in fact, it is often a symptom rather than a cure, and the water is removed from the water vapor on the wall and floor, infiltrating into the air, and the air is then discharged through dehumidification.

The general power of the dehumidifier is at least 1 kWh, the high power is 3 kWh per hour, in the humid weather, the power consumption is still very amazing, there are 30 yuan to 50 yuan per day, the key is that there is still water and mold on the wall, but the humidity in the air is small.

Therefore, it is the best choice to use the thermal insulation effect of the insulation board or thermal insulation mortar to make the temperature of the wall and the ground close to the air temperature, so as to reduce the formation of condensed water, just imagine a refrigerator thrown into a 50-meter air-raid shelter, in fact, the air inside is still dry. From a common sense point of view, it is also true that the basement that is generally made of soft packaging and European-style wainscoting will not feel very trendy when you walk in.

You can choose insulation materials with good thermal insulation performance and do not release harmful substances. The excipients are glue for pasting; There are two kinds of glue for different situations: one is for clean walls without large potholes, and you can use environmentally friendly nail-free glue.

One is foam glue. It is used on walls with a small amount of peeling or rough walls.

How to deal with too wet in the warehouse:

1. Natural ventilation method.

Natural ventilation is to use the temperature difference and air pressure difference between the inside and outside of the warehouse to open the doors, windows, vents, etc. of the warehouse, so that the air inside and outside the warehouse can be naturally exchanged. Installing an exhaust fan or air filtration device in the vent can also play a role in controlling humidity and purifying the air.

2. Mechanical ventilation method.

It is to install an exhaust fan at the upper part of the warehouse and a feeding fan at the bottom of the warehouse to strengthen the air exchange inside and outside the warehouse. There are also air filtration equipment installed in the ventilation area to improve the cleanliness of the air and reduce the temperature and humidity of the air.

3. Automatic control equipment using temperature and humidity.

Photoelectric automatic control equipment can automatically control and adjust the temperature and humidity of the warehouse, make records and save them. When the temperature and humidity of the warehouse exceed the standard, it will automatically alarm, automatically open the warehouse window, automatically start the industrial dehumidifier, automatically record, and automatically adjust the temperature and humidity in the warehouse. When the temperature and humidity in the warehouse are in the optimal range.

The industrial dehumidifier will stop working again and automatically close the ventilation window.

4. Use industrial dehumidifiers.

Industrial dehumidifiers are used to control humidity. Dehumidification with a refrigerated dehumidifier is the best way to reduce the relative humidity in the warehouse by using mechanical moisture absorption.

I hope it will be helpful to the landlord, hope.

1. Strengthen ventilation.

Use the entrance and exit passages of the underground garage to strengthen ventilation and ventilation, so as to reduce the humidity of the underground garage. Ventilation can make use of the natural ventilation brought by the building design structure, or manual intervention can be carried out to strengthen ventilation and ventilation, so that the humidity of the underground garage can be balanced with the external environment as much as possible. However, it is best to choose the ventilation time in the morning and evening, when the temperature difference between the inside and outside is not very large, which is suitable for ventilation.

The temperature difference between the inside and outside of the afternoon and noon is large, and the ventilation will exacerbate the condensation of water vapor on the wall and floor of the underground garage.

2. Use the dehumidifier appropriately.

The humidity is high in summer, especially in rainy days, at this time it is not possible to open windows or mechanical ventilation, otherwise the outdoor high temperature and humid air will be pumped in, and condensation will be produced after encountering low temperature ground and walls, which will aggravate the humid situation. At this time, the ventilation equipment should be turned off, the doors and windows should be closed, the dehumidifier should be turned on for dehumidification, the dehumidification standard should be adjusted, and the equipment should be automatically turned on or off. If you use a dehumidifier for dehumidification, it is recommended to consult a professional to help you choose the amount of dehumidification you need from the dehumidifier.

The selection of dehumidifiers can not be determined simply by area and floor height, but according to the overall wet load of the application site.

3. Reduce the temperature difference between the garage and the outside.

Rolling shutter doors can be used to block the air communication between the underground garage and the outside environment in time to avoid the moisture of the external environment from entering the underground garage. Geothermal heat can also be used to increase the ground temperature of the underground garage, thereby promoting the evaporation of air humidity in the underground garage and improving the humidity in the garage.

Underground garage roof drainage procedure.

1. Select drainage materials for different garage structures.

Molten polyhydrocarbon permeable group drainage material is a drainage material that is more commonly used in construction in recent years, mainly including pipes and plates. It has excellent water seepage and drainage functions, which not only has the effect of collecting and excluding stagnant water in the soil and reducing the groundwater level, but also overcomes the shortcomings of water permeability, no root resistance and drainage seepage at the bottom of the old seepage material.

2. Selection of substrate soil.

The substrate soil of the general landscape greening project adopts the original soil or the deep soil excavated by the foundation, and its wet weight is 1900 2100kg m3. During the construction of the garage roof, in order to reduce the structural load of the roof and strengthen the seepage and drainage capacity of the soil, the improved soil can be used for backfilling.

3. Selection of plants.

When designing the greening of the garage roof, the requirements of natural conditions should be fully considered: choose shallow-rooted barren-tolerant plants, because the garage roof is an independent space, the soil fertility loss is serious, and in order to prevent the root system from eroding the garage structure, the shallow-rooted barren-tolerant plants should be selected as much as possible. Choose wind-resistant, not easy to lodging, water-resistant plants, due to the garage roof backfill soil layer is thin, poor soil drainage performance, typhoon season and rainy season, easy to cause short-term waterlogging, so should be selected as much as possible to resist wind, not easy to lodging, water-resistant plant hall oranges.

In particular, the soil of the new building is wet, after winter and spring construction, the soil moisture is not completely evaporated, and the moisture due to the water vapor pressure difference penetrates from the outdoor soil through the building structure into the indoor moisture, and in other areas, the groundwater level changes with the season, and the moisture in the soil increases significantly in the summer, resulting in the aggravation of the wet potato wax in the summer.

The underground parking lot in summer, especially in the rainy season, the humidity phenomenon is particularly serious, because the outdoor temperature rises in summer and the relative humidity of the air is larger, and the temperature of the underground parking lot is still at a lower temperature after winter and spring, and the outer wall of the underground parking lot structure, the roof and the mechanical and electrical equipment are all metal materials with good thermal conductivity, and the lower air temperature is further maintained, so that there will be a large temperature difference and humidity difference between the basement and the outside, and ventilation is carried out under the condition of large temperature difference and humidity difference. Condensation can be generated on floors and walls, creating a damp condition.
