Family Cement Prefabricated Houses
Family cement prefabricated houses were once popular in rural areas, offering construction advantages but also having significant drawbacks. In 2025, new technology modular prefabricated houses have addressed many of these shortcomings.
Construction Advantages of Traditional Cement Prefabricated Houses: Traditional cement prefabricated houses are constructed using factory-prefabricated modules assembled on-site, enabling extremely rapid construction. For example, in rural areas of Henan, when using cement prefabricated houses, a team of several workers can build a villa in as little as four hours, and complete the construction of an entire building within two days. The costs are also relatively low, with less steel used, a simple construction process, low labor costs, and a construction cost of just over 300 yuan per square meter.
Structural and Performance Defects of Traditional Cement Prefabricated Houses: Structurally, the prefabricated panels are floor slabs processed in advance at the factory, and after on-site assembly, gaps exist at the edges of the panels. In terms of performance, the sound insulation is extremely poor; the prefabricated panels are about 10 centimeters thick with long circular holes in the middle, allowing sound to easily propagate through the voids and even be amplified. The waterproofing performance is insufficient, and the tiny gaps between the panels can lead to rainwater infiltration during the rainy season, corroding the internal steel reinforcement.
Safety Hazards of Traditional Cement Prefabricated Houses: Traditional cement prefabricated houses pose serious safety hazards. Their earthquake resistance is extremely poor, and even minor earthquakes can cause the house to collapse. The quality of prefabricated cement panels on the market varies greatly, with a majority being of inferior quality and having a short service life, potentially leading to collapse accidents without warning and causing casualties.
Improvements in New Technology Modular Prefabricated Houses: The new technology modular prefabricated houses that emerged in 2025 are made of sandwich panels (foam cement panels) and feature waterproofing, solar power supply, light weight, durability, and eco-friendliness. They have an earthquake resistance of up to Richter scale 9, a fire resistance of 2 hours, a sound insulation of 40dB, and can withstand wind loads at a wind speed of 180km/h. The main structure is made of hot-dip galvanized steel and cement. Six workers can assemble a 100-square-meter house in one day, and the houses come with a LIFETIME warranty and online technical support.
