What should I do if the underground garage leaks and the basement leaks?

First of all, we should find out the cause of water leakage. What caused it? Then deal with it according to the specific situation. Generally, it can be analyzed from the following situations.

A, the basement leakage:

Leakage in the basement usually occurs in the form of local leakage. Basements are located in different geology, different functions and different designs.

Different from buildings, its water leakage parts and forms are diverse.

1, water leakage position: local water leakage in the basement usually only accounts for a small part of the outdoor area, with several square meters.

The small one is only as big as the bowl mouth, and the area is less than one thousandth or one tenth of the area outside the basement. But the use of the basement

And durability is very harmful. About 70% of water leakage occurs on the floor, or in the deepest pit of the floor, and most of it occurs at the bottom.

The intersection angle of slab or pit (regarded as internal intersection angle indoors) is rarely in the middle and lower part of basement exterior wall.

2. Water leakage form: The water leakage form is related to geology, structure and season, mainly manifested in the following situations.

① Water inrush: When the groundwater pressure is high, the leakage flow is large, and sometimes it can't stop the continuous upwelling like spring water.

(2) Undercurrent: The water leakage in the basement will flow out along the cracks in the concrete of the building structure, just like the same undercurrent.

(3) Leakage: The leakage of the basement is injected from the outside or oozed from a certain surface of the structural concrete. Leakage degree

The difference is that after wiping the big one with a dry cloth, you will see some small water droplets come out and get wet soon; The little guy only sees wet.

Never do it, it will get wetter and wetter after half a day or a few hours.

④ Fluctuating leakage: affected by the fluctuation of basement pressure, sometimes it will leak or leak, and sometimes it will disappear.

3. Structural water leakage: refers to the hidden danger of construction quality caused by improper application of materials in basement construction joints, post-pouring belts, water stops and other parts.

The structure leaks.
