Are There Potential Issues with Concrete Prefabricated Houses?

Concrete prefabricated houses do have some potential issues that require attention, mainly reflected in the following aspects:

Cost: Some merchants may offer low initial quotes that only cover the price of the bare walls, while items such as foundations, transportation, hoisting, waterproofing, and decoration all require separate charges. When all costs are taken into account, the total cost of a regular prefabricated house may be 10%-30% higher than that of a traditional brick-and-mortar house, making it not actually cheap. Consumers need to be wary of low-price traps and avoid budget overruns due to hidden costs.

House Flexibility: Once a concrete prefabricated house is built, its location is fixed, and the water and electricity pipelines are embedded within the walls. If additional sockets need to be added, room layouts adjusted, or functional partitions renovated later, the construction difficulty is extremely high, and it may even damage the wall structure. Therefore, during the design phase, it is necessary to fully consider living needs for the next decade or even longer; otherwise, numerous inconveniences may be encountered after moving in.

Quality: There are a large number of prefabricated modules produced by small workshops in the market. These workshops lack standardized factories and constant-temperature curing conditions, often using inferior cement, simplifying steel bar configurations, and even pouring concrete outdoors. Such products may experience issues such as wall cracking, water leakage, and wall peeling within two years after assembly, and merchants may run away due to quality problems, making it difficult for consumers to defend their rights.

Spatial Layout: Due to the limitations of modular production, the personalization level of the spatial layout of prefabricated houses is relatively low, and it is difficult for the dimensions of regional functions to meet detailed needs. For example, the positions of doors and windows and the thickness of walls may not fully fit actual usage scenarios, affecting living comfort.

Sound Insulation and Thermal Insulation: The walls of prefabricated houses are generally thin, resulting in poor sound insulation and thermal insulation performance. In extremely cold or hot regions, additional thermal insulation layers need to be added; otherwise, problems such as cold winters and hot summers may be faced, increasing energy consumption.

Connection and Fixation: The connection of prefabricated modules relies on grout joints, which have high technical requirements, and ordinary construction teams find it difficult to ensure quality. Buildings of three stories or more have potential safety hazards, and there are inevitably gaps at the module joints, which are prone to cracking later and require regular maintenance.
