How About Cement Prefabricated Houses

Cement prefabricated houses have both advantages and disadvantages, and the decision to choose one should be based on specific needs and scenarios.

Advantages:

• Fast construction speed: The construction process is similar to building with blocks. After the prefabricated cement slab components are transported to the construction site, a few workers can complete the assembly of a villa in just four hours, and it takes only two days to build an entire building. For example, a 100-square-meter house can be assembled in one day, which is 90% faster than traditional construction methods. This truly enables the possibility of hoisting today and moving in tomorrow, significantly improving efficiency and greatly shortening the construction period compared to traditional methods.
• Low cost: The cost per square meter is only around 300 RMB. The cost of a large villa is just over 100,000 RMB, which is much lower than that of traditional brick-and-mortar houses. For a 100-square-meter house, it saves 60,000 RMB compared to a brick-and-mortar structure, and generates 90% less construction waste, greatly reducing the financial burden on rural families.
• Strong earthquake resistance: It can withstand a magnitude 9 earthquake and has good structural stability. After three years of use, the overall structural stability remains good, indicating strong durability and earthquake resistance of the house.

Disadvantages:

• Poor sound insulation and moisture resistance: The sound insulation and moisture resistance are inferior to those of ordinary brick houses. The probability of roof leakage in prefabricated houses is 30% higher than that of brick houses. After three years of use, during the rainy season or high-temperature seasons, small problems such as leakage and dampness may occur inside the house.
• Poor thermal insulation: Poor thermal insulation leads to a 20-30% increase in air conditioning electricity costs.
• Discrepancy between design life and actual life: The design life is 60 years, but major repairs are required after about 40 years of actual use.
• Inflexible design: The appearance is relatively monotonous, and the modular architectural design may lack flexibility, making it difficult to meet the diverse needs of everyone.
• Requires maintenance: The house requires regular maintenance and inspections to ensure its service life and safety.

If it is for temporary housing or in earthquake-prone areas, cement prefabricated houses can be a good choice; however, for long-term residence, especially in humid areas or for those who require a quiet environment, traditional brick houses are more reliable. If you plan to live in a cement prefabricated house for a long time, it is recommended to install sound insulation cotton and thermal insulation boards, and ensure proper waterproofing at the roof joints.
