Interior Wall Cracks in Prefabricated Panel Houses

Interior wall cracks in prefabricated panel houses may be caused by factors such as structural defects in the house and ground subsidence, requiring timely identification and handling.

Structural defects in the house are one of the main causes

Prefabricated panel houses inherently have the drawbacks of low structural strength and poor earthquake resistance. They are assembled from individual prefabricated panels, and this assembly method results in a lack of robustness and resilience in the house. Over time, under the long-term influence of its own weight and external environmental factors (such as temperature changes and humidity changes), cracks are prone to appear in the walls. For example, in the west households on the first to fourth floors of Unit 2, Building 7, No. 1382 Shuangta First Road, Yingze District, Taiyuan City, the walls in their homes have varying degrees of cracking, which is a typical case of wall cracks caused by structural defects in the house.

Ground subsidence is also an important factor

Ground subsidence refers to a phenomenon where the earth's surface gradually descends as a whole under natural conditions or under the influence of human activities. When ground subsidence occurs, the rate of subsidence may vary at different locations. For a building, if the left and right sides subside unevenly, it is likely to cause wall cracking. Earthquakes, volcanic eruptions, excessive groundwater extraction, underground mineral mining, and underground construction work can all potentially cause ground subsidence, which in turn leads to wall cracks in prefabricated panel houses.

Wall cracks may be accompanied by other problems

Prefabricated panel houses also have issues such as a short service life, susceptibility to water leakage, and poor thermal insulation. After wall cracks appear, situations like water seepage may also occur. This will not only further damage the house structure but also affect the living experience, reducing the comfort and safety of living.

Countermeasures

According to Article 16 of the 'Taiyuan House Safety Management Measures', after a house is delivered for use, the house owner or user should apply to a house safety identification agency for identification to determine whether the prefabricated panel house with wall cracks is a dangerous building and whether it can continue to be inhabited, so as to take corresponding handling measures and ensure living safety.
