Terrible Disadvantages of Prefabricated Concrete Houses
Prefabricated concrete houses do have some disadvantages and hidden dangers that are considered 'terrible', mainly reflected in the following aspects:
I. Prominent Safety Hazards
The structural stability of prefabricated concrete houses is relatively poor. In the event of a minor earthquake, the risk of house collapse increases significantly. This is mainly because the connection methods between prefabricated components are mostly splicing or simple fixation, resulting in insufficient integrity. Additionally, the quality of prefabricated concrete slabs on the market varies greatly, with a high proportion of inferior products. Their service life is often short, and they may break or collapse without warning, directly threatening the lives of occupants.
II. Poor Sound Insulation
The thickness of prefabricated slabs is usually around 10 centimeters, and they have long circular holes in the middle. This structure makes sound highly penetrable. Noise from neighboring rooms not only easily passes through the holes in the prefabricated slabs but may even be amplified, seriously affecting the quality of life of occupants, especially at night or in environments that require quietness.
III. Widespread Water Leakage Issues
Prefabricated slabs are composed of independent panels joined together, and there are tiny gaps between the panels. Rainwater can easily seep into the interior through these gaps. Long-term leakage not only corrodes the internal steel bars, reducing the structural strength of the house, but may also cause problems such as mold growth and wall peeling, further affecting the service life and safety of the house.
IV. Limited Spatial Layout
The walls of prefabricated concrete houses are relatively thin, and their sound insulation and thermal insulation performance are poor. Especially in cold regions, additional thermal insulation treatment is required. Moreover, their spatial layout has a low degree of personalization and is difficult to meet diverse living needs. Poor connection and fixation are also major issues. If a low-rise building wants to be raised to three stories or more, the risk increases significantly, and problems such as gap cracking are inevitable during the assembly process.
V. High Construction Requirements
When building prefabricated concrete houses in rural areas, the joint treatment of the grouting material used for connections requires professional skills and equipment, which ordinary construction teams find difficult to handle. If not handled properly, it will not only affect the overall stability of the house but may also pose safety hazards.
