How to solve the problem of moisture in underground garages?

For the vast majority of newly created real estate residential projects and office buildings, underground garages require an indispensable equipment accessory. Parking a car in an underground garage can not only alleviate the problem of busy parking spaces on the ground, improve the utilization of road space, but also reduce the adverse effects of climate conditions on the car.

But there is an inevitable puzzle in underground garages, which is dampness. The damp underground garage has caused great harm to both real estate developers and homeowners. For real estate developers, the dampness of underground garages directly affects the quality of all real estate projects, harms corporate brands, and can cause dissatisfaction among property owners, exacerbating conflicts between real estate developers and property owners.

For homeowners, the wet road surface of the underground garage makes it very easy for cars to deviate, which can easily cause safety accidents, especially in the import and export trade of the parking lot, with higher risks. The car is parked in a humid living environment for a long time, causing the engine, chassis, distribution lines, etc. to become damp and rust, accelerate oxidation, and malfunction.

During the construction of engineering buildings, concrete, bricks and coatings all contain certain moisture, which has not yet evaporated completely after completion. When the outdoor temperature rises, it evaporates into the room, making the room moist.

The temperature difference inside and outside the underground parking lot, as well as the difference in environmental humidity, result in condensation water conditions, which are particularly severe in humid summer underground parking lots, especially during the rainy season. Mainly because the outdoor temperature increases in summer and the relative humidity is relatively high, while the temperature of the underground parking lot is still relatively low in winter and spring. In addition, the walls, cast-in-place slabs, and mechanical equipment used in the underground parking lot are made of metal composite materials with good thermal conductivity, which further maintains a relatively low air temperature. As a result, there will be a significant temperature difference and environmental humidity difference inside and outside the villa basement, Natural ventilation in a temperature difference and temperature difference environment can cause condensation on the floor and walls, resulting in humid conditions.

In summer, there is frequent heavy rainfall, coupled with typhoons in southern regions and coastal cities, resulting in frequent heavy rainfall. In the short term, the amount of extremely heavy rain usually accumulates rapidly on the ground, and the precipitation that cannot be drained will flow back into the relatively low terrain underground parking lot. Even after the rain is over, the backflow precipitation will be removed through maintenance and other means. The volatile water vapor, such as the walls that have already been soaked by water, will evaporate again, causing the underground parking lot to be damp. There are so many hazards of moisture in underground garages, which have also brought many troubles and troubles to people. In fact, dealing with moisture in underground garages is not difficult. Long term dehumidification can control the humidity in underground parking lots within an ideal range.
