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.
Why is there dampness in underground garages?
1. Structural seepage
The compaction degree of cement soil, moisture resistance of concrete surface, sorting of settlement joints, and sealing of pipeline holes are related, and these reasons are relatively immediate. Especially for newly created engineering buildings, the soil layer is damp. Through winter and spring construction, the soil moisture content is not completely evaporated, and water seeps into the room due to the water vapor pressure difference from the soil layer according to the building structure, resulting in the room being damp; In other regions, groundwater changes with seasons, and the moisture in the soil layer significantly increases in summer, resulting in an aggravation of humid conditions in summer.
2. Volatilization of structural moisture content
During the construction of engineering buildings, concrete, bricks, and coatings all contain a certain amount of moisture. After completion, the moisture has not yet completely evaporated, and it evaporates into the room while the outdoor temperature rises, causing dampness in the room.
3. Temperature difference and environmental humidity difference inside and outside the underground parking lot
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.
4. heavy rainstorm and other heavy rainfall weather lead to surface water backflow.
There are many heavy rains in summer. In addition, Upland South regions and coastal cities are subject to typhoons, which often lead to 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.
