Prefabricated Panel Houses in Chengdu

Prefabricated panel houses in Chengdu are characterized by low cost, short construction periods, but generally average quality. They face waterproofing challenges, with demolition policies varying depending on the house. Renovation requires attention to the condition of the prefabricated panels, and there are various prefabricated panel products available for sale.

House Characteristics

Prefabricated panel buildings are constructed using cement panels that are produced in advance by mixing building materials. Most prefabricated panels are hollow, which helps save on construction costs and shorten construction periods. However, due to lower living standards and less mature construction techniques in the past, the quality of these buildings is generally relatively low.

Waterproofing Issues

Chengdu has a humid and rainy climate, and many old residential areas feature prefabricated panel floors. The gaps between panels serve as natural channels for water leakage. If waterproofing is inadequate, water can easily seep horizontally through these gaps to adjacent rooms or even downstairs. Moreover, the high humidity in the Chengdu Basin allows moisture to penetrate everywhere, leading to high moisture content in walls and floors. Poor waterproofing can result in problems such as peeling, mold, and脱落 (which means 'flaking off' or 'coming loose' in English, here it can be translated as 'flaking off' to convey the idea of wall surface deterioration) of wall finishes, seriously affecting living comfort and the structural safety of the building.

Demolition Policies

Chengdu does not have a unified policy for demolishing prefabricated panel houses. Houses that are old, highly dangerous, and have little renovation value will be demolished. If the house structure is relatively good and still has a certain service life, it is more likely to be repaired to extend its lifespan and ensure the safety of residents.

Renovation Considerations

When renovating old step-prefabricated panel houses in Chengdu, after removing the tiles on the prefabricated panels, there may be holes in the panels. During the renovation process, these holes need to be properly treated, such as by filling and reinforcing them, to ensure the stability and safety of the building structure.
