Failure of Finished Prefabricated Cement Houses

The failure of finished prefabricated cement houses can be caused by multiple factors, covering aspects such as quality, performance, design, application, and legal issues.

Quality and Legal Liability

If the quality of a prefabricated cement house does not meet the agreed standards due to construction reasons, according to Article 801 of the Civil Code of the People's Republic of China, the construction unit shall be liable. The employer has the right to request the constructor to carry out free repairs, rework, or reconstruction within a reasonable period. This indicates that non-standard operations during the construction process are an important legal factor contributing to the failure of the finished product.

Performance Defects

• Safety hazards: There are serious safety hazards. For example, even a minor earthquake can cause the house to collapse. The quality of prefabricated cement panels on the market varies greatly, with a large proportion of inferior products and extremely short service lives, directly threatening the safety and durability of the house.
• Sound insulation issues: The sound insulation ability is extremely poor. The thickness is insufficient, and the structure easily transmits sound. High-volume speech in one room can be heard in the adjacent room, seriously affecting the privacy and comfort of living.
• Water leakage problems: Water leakage is a common issue. There are tiny gaps between the panels, allowing rainwater to easily seep in and corrode the steel bars, not only damaging the house structure but also potentially causing indoor dampness and mold problems.
• Poor disaster resistance: Most prefabricated cement houses cannot withstand the impact of natural disasters such as earthquakes and floods. They are prone to damage or even collapse under extreme weather conditions.
• Poor thermal insulation: The houses are cold in winter and hot in summer, providing a poor living experience and increasing energy consumption and living costs.

Design Defects

• Dull appearance: The buildings have a monotonous appearance, lacking aesthetic appeal and personalized design.
• Inhumane room design: For example, small living rooms without windows, and bathrooms and kitchens without windows leading to long-term dampness, affecting the comfort and health of living.
• Poor waterproofing ability: If a resident on the upper floor forgets to turn off the faucet, the house below may be flooded, indicating serious deficiencies in the house's waterproofing design.

Application Challenges

• Transportation and hoisting difficulties: In cultural and tourism project applications, the building components are large in volume and heavy in weight, subject to limitations in transportation road conditions and on-site hoisting conditions, increasing construction difficulty and costs.
• High customization costs: The structures are mostly irregular in shape, and the doors, windows, decorative materials, electrical and lighting equipment on the market often need to be customized, raising the overall cost.
• Cost-effectiveness and aesthetic issues: Limited investment can be made in secondary decoration, making it difficult to achieve an appearance that meets public aesthetic standards, affecting the market acceptance and value of the houses.
