Leakage in House with Prefabricated Slab Buildings

Leakage in prefabricated slab buildings requires timely repair and should not be merely addressed with surface treatments. The owner of the house should bear the responsibility for repairs, and classification and disposal can be carried out in case of severe aging.

Causes of Leakage

Leakage problems in prefabricated slab buildings are relatively common, mainly related to the characteristics of the prefabricated slabs themselves and the aging of the buildings. On the one hand, the interior of the prefabricated slabs may be hollow, making it difficult to completely solve the leakage problem through surface repairs. On the other hand, during the normal floor leveling construction, there may be many cracks in the prefabricated slabs, and the bonding between the previous mortar layer and the prefabricated slabs was not good, which further increases the likelihood of leakage. For example, Building 9 in Area 2 of Xiangnongqiao Community, Yuhua District, Changsha City, which uses prefabricated slabs, has suffered from leakage in the top-floor households and seepage to the lower floors due to long-term disrepair; a brick-concrete structure building built in 1993 in Area 1 of Anding Community, Mocheng Street, Changshu City, Jiangsu Province, also has roof seepage issues.

Repair Responsibilities

The owner of the house is the person responsible for the safety of the house's use and is required to undertake the responsibility of inspecting and repairing the house and promptly addressing potential safety hazards. When leakage problems occur in a prefabricated slab building, the owner should promptly repair the house and not delay, so as to prevent the leakage problem from further deteriorating and affecting the structural safety of the house and the living comfort.

Classification and Disposal

If the house is severely aged, such as being identified as a Class C or D dilapidated building, classification and disposal can be carried out through methods such as expropriation, repair and reinforcement, or demolition and reconstruction. For leakage problems in prefabricated slab buildings, if the overall aging degree of the house is high, simple repairs may not be able to fundamentally solve the problem. In this case, an appropriate disposal method should be selected according to the specific situation of the house. For example, for some houses with historical value or special significance, repair and reinforcement may be more suitable; while for some severely aged houses that cannot meet the requirements of living safety, demolition and reconstruction may need to be considered.
