Prefabricated Floor Slabs for Houses in Liuzhou

Prefabricated floor slabs for houses in Liuzhou have issues such as insufficient seismic performance and safety hazards when installing elevators, but there is a relevant prefabricated component production industry in the local area.

Insufficient Seismic Performance

Prefabricated slab houses use a construction technique where pre-cast floor slabs are laid on walls. This technique was mainstream decades ago. However, it has an inherent problem of insufficient seismic performance. The connections between prefabricated slabs are often not tight enough, and there are inherent physical structural flaws that cannot be resolved through simple repairs. For example, during the 5.2-magnitude earthquake that struck Liuzhou, Guangxi, in the early morning of May 18, 2026, 13 prefabricated slab houses in the area collapsed directly, resulting in casualties and missing persons, while fully cast-in-place houses remained intact. This stark contrast clearly highlights the poor seismic performance of prefabricated slab houses.

Issues with Elevator Installation

Many old residential areas consider installing elevators to facilitate the travel of elderly people with mobility issues. However, for prefabricated slab houses, externally mounted elevators pose significant safety hazards. Installing an elevator requires cutting or drilling holes in the original building structure, which can cause secondary damage to the already fragile prefabricated structure. Moreover, even if the elevator is successfully installed, the connection points between the elevator shaft and the building may become weak points during an earthquake. Therefore, installing elevators in prefabricated slab houses requires highly professional assessments and should not be done blindly.

Market Production Situation

Although prefabricated slab houses have some issues, Liuzhou has a certain industrial foundation in the production of prefabricated components. There are assembly-type building component production workshops in the local area that produce concrete prefabricated component models. In recent years, the focus has been on developing emerging green building materials, assembly-type buildings, and other environmentally friendly industries, with the production of prefabricated concrete components and other building industries as the main development directions. The industrial chain is being continuously improved, and the application of assembly-type building components is being actively promoted. There are numerous manufacturers in Liunan, Liuzhou, that produce prefabricated-related products such as laminated slabs, prefabricated stairs, and PC components, serving multiple areas including Liucheng County, Liubei District, Rongshui Miao Autonomous County, and Yufeng District.
