Why is it difficult to cure the rain leakage in many old communities in Beijing?

The main reasons why it is difficult to cure the problem of rain leakage in many old residential areas in Beijing are: aging buildings, difficulties in maintenance, lack of financial support, inadequate property management, difficulties in urban renewal and technical problems.

1, building aging

Many old residential buildings are very old and their structures are aging. The aging of building materials, the generation of cracks and the blockage of drainage system will all lead to the problem of rainwater leakage. Because the buildings in these old communities have existed for many years, it needs a lot of money and manpower to carry out comprehensive restoration and transformation.

2. Maintenance is difficult.

Due to the age of old residential buildings, many buildings are outdated and difficult to maintain. For example, the roofs of some old residential areas are designed as flat roofs, while modern buildings mostly use inclined roofs, which makes it more difficult to maintain the roofs. In addition, the drainage system in some old communities is aging, and it takes a lot of time and money to replace it.

3. Lack of financial support

The maintenance and renovation of old residential areas need a lot of capital investment. However, due to the relatively poor economic situation of some residents in old residential areas, they lack sufficient financial support. The government is also facing financial pressure in repairing old residential areas, and often cannot provide enough financial support to solve the problem of rain leakage.

4. Property management is not in place.

The property management level of some old residential areas is relatively low, and there is a lack of professional maintenance and management personnel. Property companies pay insufficient attention to the problem of rain leakage, which leads to the problem not being solved in time. In addition, the owners of some old residential areas have a weak sense of autonomy and lack of awareness of active maintenance and management, which also aggravates the problem of rain leakage.

5. Urban renewal is difficult.

Because of the huge scale of old residential areas, it is an arduous task to carry out comprehensive urban renewal and transformation. The interests involved are complicated and need the coordination of the government, developers and residents. Therefore, the process of urban renewal is slow, which leads to the problem of rain leakage in old communities can not be fundamentally solved.

6. Technical problems

Due to some limitations of building structure and design in old residential areas, it is necessary to adopt appropriate technical means to solve the problem of rainwater leakage. However, the structure and facilities of some old residential areas are outdated and cannot meet the modern waterproof standards.
