Does water leakage in the underground garage affect the life of the building?

Shopping malls and residential buildings are basically equipped with underground garages, and the leakage of underground garages due to the quality of construction has also increased, which will not only have a certain impact on the building itself, but also bring a lot of inconvenience to the owners.

Hazards of water leakage in underground garages: the internal steel bars are seriously corroded, threatening the safety of the building itself; If the underground garage leaks, the internal humidity will increase, causing the harm of the vehicle, affecting the safety of the owner, and when the temperature difference is large, it will also fog up, affecting the line of sight; The foundation sinks and cracks, affecting the service life of the building.

Causes of leakage in underground garages.

1. The concrete pouring vibration is not solid, and the structure is loose.

2. The construction is not done well, the foundation is not well disposed of, and the building produces uneven settlement, resulting in structural cracking and waterproof layer destruction.

3. The concrete ratio problem is not well matched.

The traditional waterproofing can only solve the problem of underground garage leakage for a while, but the durability is poor, and the persistence is not long, if you want to solve the problem of underground garage leakage in the real sense, you must find the right professional management of underground garage leakage company, do not blindly, according to the cause of underground garage leakage, specific problems are analyzed.

Over time, the foundation of the whole house can be unstable, and if it sinks, it will lead to cracking of the wall, which will seriously affect the service life.

Severe corrosion of the stability of the inside of the concrete, cracking, powdering, shelling, internal steel corrosion are the most common hazards, the most serious is that long-term water seepage will weaken the strength of the concrete, threatening the safety of the building.

In addition, due to the leakage of the underground garage, the internal humidity of the underground garage will be large, which will cause some hazards to the vehicles parked in the underground garage, such as short circuits due to moisture in the circuit.

Causes of water seepage and leakage in underground garages.

1. Honeycomb and holes. This is mainly caused by the non-compactness of vibration, improper vibration or insertion, vibration leakage or excessive slurry leakage of formwork joints during the pouring of Shanghai concrete.

2. Leakage occurs at the tie rod. This is mainly due to the poor welding quality of the water-stop piece in the middle of the tie rod, or the concrete strength does not meet certain requirements before the mold is removed in advance, so that the tie rod rotates, or it may be that the outer side of the tie rod is not treated with anti-seepage after the outer wall is dismantled.

3. The setting of the hanging formwork support at the concrete flap of the bottom plate is unreasonable, resulting in water seepage and water leakage. This is mainly the support of the foot wood block on the cushion, when the lifting mold is removed has passed the concrete final setting time, the hole left is very easy to leak.

4. The original waterproof layer is destroyed when the external backfill is made.

5. The concrete vibration is not compact, and the structure is loose.

6. The formwork was dismantled too early in the later stage, and the structural cracks and leakage caused by the rolling of the cart were leaked.

Legal analysis: If the basement leaks and belongs to the public area, the property shall be responsible for the damages caused by it, and the property shall bear the compensation.

Legal basis: Property Management Regulations

Article 2 The term "property management" in these Regulations refers to the activities of the owners through the selection of property service enterprises, and the owners and property service enterprises in accordance with the property service contract to repair, maintain and manage the housing and supporting facilities and equipment and related sites, and maintain the environmental sanitation and related order in the property management area.

Article 55: When there are potential safety hazards in the property, endangering the public interest and the lawful rights and interests of others, the responsible person shall promptly repair and maintain it, and the relevant owners shall cooperate. If the responsible person does not perform the maintenance obligation, with the consent of the owners' general meeting, it can be repaired and maintained by the property service enterprise, and the cost shall be borne by the responsible person.

Legal analysis: Garage leakage should generally be held responsible by the developer.

Legal basis: "Measures for the Administration of the Sales of Commodity Housing" Article 33 Real estate development enterprises shall bear the responsibility for the quality warranty of the commercial houses sold. The parties shall make an agreement on the scope of the warranty, the warranty period, the warranty liability, etc. in the contract.

The warranty period is calculated from the date of delivery. The warranty period of commercial housing shall not be less than the duration of the warranty period agreed in the quality warranty issued by the construction project contractor to the construction unit; If the duration is less than the minimum warranty period determined in the Provisions, the warranty period shall not be lower than the minimum warranty period determined in the Provisions. The warranty period of non-residential commercial housing shall not be less than the duration of the warranty period agreed in the quality warranty issued by the construction project contractor to the construction unit.

If the quality problems that occur within the warranty period and fall within the scope of the warranty, the real estate development enterprise shall fulfill the warranty obligation and bear the liability for compensation for the losses caused. The real estate development enterprise shall not be liable for the damage caused by force majeure or improper use.

1. Garage leakage is divided into the following situations according to the specific situation:

1) If the owner's vehicle is flooded or invaded by water due to water leakage and other reasons in the garage, the property shall be responsible for compensation;

2) The property will not compensate for rainwater or other external water sources poured into the underground garage due to natural disasters, such as typhoons, rains and other extremely bad weather. According to the relevant laws of China, extreme weather in nature is a force majeure, and the management unit shall not be liable for the loss of collective, unit and individual economic property caused by force majeure. If the management unit is covered by public liability insurance, it can be compensated by public liability insurance within the insured amount.

2. Legal basis: Article 286 of the Civil Code of the People's Republic of China.

Owners' meetings or owners' committees; Acts that harm the legitimate rights and interests of others, such as arbitrarily disposing of garbage, discharging pollutants or noise, raising animals in violation of regulations, building in violation of regulations, encroaching on passages, and refusing to pay property fees; the right to comply with laws, regulations and regulations; Request that the perpetrator stop the infringement, remove the obstruction, eliminate the danger, restore the original state, and compensate for the loss.

The owner or other actor refuses to perform the relevant obligations; The relevant parties may report or complain to the relevant administrative departments; The relevant administrative departments shall handle it in accordance with law.

2. What are the garage transfer processes?

1. Sign the contract and pay. It is necessary to ensure that the signed contract is true and valid;

2. Tax payment and transfer. It is necessary to prepare personal income tax, value-added tax, deed tax, property registration fee, stamp duty, etc.;

3. Receive a new property right certificate.

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.

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.
