Issues with Concrete Prefabricated Houses

Concrete prefabricated houses have issues such as safety hazards, poor sound insulation, water leakage, short design lifespan, lack of humanized room design, and potential legal problems. Details are as follows:

Safety hazards: On one hand, if the assembly and splicing during the construction process are improper, the house is highly likely to collapse in the event of a minor earthquake. On the other hand, the quality of prefabricated concrete slabs on the market varies greatly, with many inferior products having an extremely short service life, which can also lead to house collapse accidents. In addition, there are gaps at the edges of the slabs, which are significantly different from cast-in-place slabs and are the root cause of safety hazards.

Poor sound insulation: The thickness of prefabricated slabs is usually insufficient, and sound has strong penetrating power. Some houses can hardly serve as sound insulation. Their structure itself is also prone to sound transmission. The thickness is generally around 10 centimeters, with long circular holes in the middle, which act as natural sound transmission devices. The noise from the next door can even be amplified after being transmitted through these holes.

Water leakage: Prefabricated slabs are composed of independent slabs spliced together, and there are tiny gaps between the slabs. During the rainy season, rainwater can easily seep into the interior of the house through these gaps, which in turn corrodes the steel bars and affects the structural safety of the house.

Short design lifespan: The design lifespan of concrete prefabricated houses is only about 30 - 40 years, while the design lifespan of current commercial houses is 70 years. Many prefabricated houses built in the 1970s and 1980s have exceeded their design lifespan and have many safety hazards.

Lack of humanized room design: Most concrete prefabricated houses were built in the 1970s and 1980s. They have problems such as no windows in the kitchen and bathroom, narrow living rooms, and dim lighting, which cannot meet modern living needs.

Potential legal problems: In terms of building compliance, legality depends on whether it complies with local building codes and standards. If the construction process does not strictly follow relevant regulations and standards, it is not legally compliant. Regarding property registration, if the construction complies with planning requirements and complete construction materials and supporting documents can be provided, property registration can usually be carried out. Otherwise, registration may not be possible, affecting the confirmation of house ownership and transactions. In terms of contracts and transactions, if the contract terms are unclear or there is fraud, it may lead to transaction disputes and legal risks. Regarding adjacent relationships and land use, if it affects the rights and interests of neighbors such as sunlight and ventilation, or if there is a dispute over the land use rights of the house, improper handling can lead to disputes and affect the normal use of the house and the protection of rights and interests.
