What are the causes of water seepage on the walls of underground garages?

The solution of water seepage on the ground of the underground garage is: use the pressure to inject the grouting plugging spirit (water soluble) into the needle, and wait for the plugging spirit to seep out from the concrete surface around the needle to produce a gelatinous solidified substance, which means that the seepage point has been closed to the seepage waterway, and the water seepage can be solved by pulling out the needle.

The common parts of basement water seepage, most of the common basement water seepage parts appear in some special parts, and the outdoor pipes are blocked or the road surface is not well drained in the rainy season when there is more precipitation. It mainly occurs in the following parts: the root part of the exterior wall; wall parts on both sides of the basement deformation joint; sewer pipes that cross the exterior wall of the basement;

Usually the underground garage leakage is caused by the leakage of the construction joint, if the construction joint is not cleaned in the construction, the strength of the concrete does not reach.

Extended information: The introduction of water seepage on the ground of the underground garage is as follows:

When the underground garage is poured with waterproof concrete, because the concrete consistency does not meet the requirements and the vibration is not sufficient, there will be a small area of honeycomb, rotten roots and other problems after the mold is removed, and only the surface layer is treated.

After the underground garage is added with water, because the water pressure increases, the concrete is thin and there is some water leakage, and the surface and the inside are not leaked, and then the underground garage floor, roof and side wall waterproof cement mortar plastering surface is 20mm thick. In the case that the water seepage problem is not severe, the Ansai waterproofing agent can be purchased, and then the mortar can be used according to the share.

No matter what kind of house it is, there will be a lot of problems after a long time, so I'll talk about itWater seepage on the wall of the underground garageand the processing methodWater seepage on the wall of the underground garageCauses.

1. Repair the plastering layer on the wall. Under normal conditions, the plastering layer is divided into 2-3 repairs. And adding an appropriate amount of micro-expansion agent to the repaired mortar can reduce the cracks at the interface between the old and new lime.

2. Wait for the coating to dry, then apply the coating to the exterior wall, and then apply one or two layers of waterproof coating, but the waterproof coating should be applied after the exterior wall paint is dry.

Water seepage on the wall of the underground garageIf there are large areas of cracks in the exterior wall, the plastering layer must be cut by cutting the wall first before cutting the wall, which can effectively prevent the vibration caused by the plastering layer during the cutting process.

4. After removing the plastering layer, be sure to clean the base layer, and then place a layer of steel mesh between the masonry and the structure to prevent the plastering layer from cracking again.

1. Through the previous explanation about the seepage wall, I think my friend has already understood. There are many reasons for water seepage. For example, when building walls, the cement mortar is not full enough and the gray space is relatively large, which can make the capillary channel a siphon.

Secondly, the poor material of the interior decoration surface material will also lead to water dispersion and leakage. If the thickness of the outer wall surface is uneven, the surface of the wall will peel off easily.

2. If there is water seepage around the window, it means that there is no sealing paste on the window frame and back plug wall, or the protective cover of the window frame is not damaged. These reasons can lead to leaks in the walls.

Water seepage on the wall of the underground garageSince the restroom is an area with a lot of water, the walls are prone to water seepage. For example, bathing and washing in our daily lives have been used for a long time and are prone to small cracks. Secondly, when the water pipe buried in the wall is used for a long time, water leakage will occur, resulting in different degrees of moisture on the surface of the wall.

The water seepage in the underground parking space is likely to be the developer's waterproofing, and if this problem occurs if it is not done well, you can communicate with the developer whether the parking space can be replaced.

It may be caused by some problems with the pipes, or because of the dampness, be sure to pay attention to ventilation and pay attention to check the location of water leakage.

The waterproofing layer is not done. The waterproof layer of the underground parking space is a very important link. If the waterproof layer is not done well, the design is not in place, the joints are not properly handled, and the bonding is not strong enough, the floor will be prone to leakage in the later stage.

Hello, happy with your question. Your question is whether the total water seepage on the ground of the underground garage of the building is harmful to the building, and the water seepage on the ground of the underground garage of the building is caused by the high groundwater level and the waterproof layer of the basement is not well constructed. The reason why this kind of water seepage is not harmful to the building is that the foundation of the building is the foundation of the well pile and the raft foundation, and the well pile is constructed in the groundwater, but the well pile is sitting on the underground pebble layer, and the pebble layer is the bearing layer of the foundation, so no harm will occur, and these factors have been considered in the drawing design.

Hello, water seepage from cracks in the underground garage can have an impact on the building, especially if it persists for a long time and is exacerbated. The following are the possible impacts:1

Unstable building foundation: If water seepage from the underground garage causes the soil to soften or wash, it can have a negative impact on the building foundation. 2.

Structural damage: The structure of the building is under great weight and pressure, and if the water seepage in the garage causes cracks in the structure of the building, it may cause serious consequences such as collapse and wall falling off. 3.

Corrosion of steel bars: If the seepage contains corrosive substances such as salt, it will corrode the steel bars, which may affect the structural safety of the building. Therefore, in order to avoid risks, it is recommended to detect the water seepage problem of the garage as soon as possible and take corresponding measures to solve it to ensure the safety of the entire building.

Yes, water seepage from cracks in the underground garage may affect the building to some extent. Crack water seepage can cause moisture in the interior and exterior walls of the building and produce corrosive gases, which can lead to corrosion of rebar and other components, which can compromise the structural safety of the building. In addition, if the crack seepage is caused by an abnormality in the drainage system, it will cause the water flow to change and bend, which in turn will cause the building to move vertically and horizontally, causing cracks in the building structure.

In addition, water seepage in the basement can also affect the structure of the building, causing cracks and even collapse. Other studies have shown that water seepage in the underground garage will also have a certain impact on the health and well-being of residents in the building, such as causing carbon dioxide to stay indoors for too long, air pollution will also be aggravated, and there are obvious hidden dangers. Therefore, it is necessary for the cracks and water seepage in the underground garage to be cleaned up and repaired in time.

It is recommended to take measures to avoid water seepage in the underground garage: first, waterproof measures should be taken in the basement of the building, second, regular inspection of the basement water seepage, timely detection of problems and timely measures, and third, build a reasonable rainwater drainage system so that rainwater will not seep into the garage.

Water seepage from cracks in the underground garage will affect the building, and may even have a negative impact on the structure of the building and the integrity of the oak. Because the infiltrated water in the building is easy to displace over time, the concrete foundation and the supporting structure exert potential pressure, which will cause cracks and adjustments in the building structure after a period of time. If the seepage can not be treated in time, it will cause a large amount of water to soak after the structural cracks, with the change of temperature and the stress of dampness and heat, the water seepage on the ground will endanger the stability of the building, and even lead to the dumping of the building.

In addition, when water seeps into the building, the moisture effect can easily corrode the building components, which may also lead to a decrease in the load-bearing and seismic performance of the building. In addition, water seepage can also destroy the space efficiency and comfort of the underground car park, and the underground garage will be filled with sewage, especially in winter, which may freeze and form condensation. In addition, water seepage can also cause corrosive gases to enter the building, which can endanger the health of the people in the underground garage and the building.
