Does the Prefabricated Panel House Have Water Leakage Issues?
Prefabricated panel houses have water leakage problems. The following elaborates on the water leakage situations from different parts in detail:
Ground water leakage: The ground of a prefabricated panel house is a relatively common area for water leakage. This is mainly because during the manufacturing and installation process of the prefabricated panels, there may be some tiny gaps or holes. When there is water accumulation on the ground or a rise in the groundwater level, water can easily penetrate into the room through these gaps or holes, causing the ground to become damp and even affecting the furniture and items inside. For example, in some old prefabricated panel houses, during continuous rainy weather, water may accumulate on the ground and take a long time to dry, which is a manifestation of ground water leakage.
Joint water leakage: Joints are a high-risk area for water leakage in prefabricated panel houses. During installation, multiple panels need to be joined together. If these joints are not properly handled, hidden dangers will remain. Over time, the sealing materials at the joints may age and crack, losing their waterproofing function. When rainwater or external water sources come into contact with these joints, water will seep into the house along the gaps. For instance, the joints of the roof prefabricated panels, after long-term exposure to wind, sun, and rain, the sealant may gradually fall off, causing rainwater to leak into the room through the joints, resulting in problems such as ceiling dripping and wall mildew.
Water leakage in other parts due to cracking and deformation: In addition to the ground and joints, as time goes by, the roof, walls, floors, and other parts of a prefabricated panel house may develop cracks and deformations, further leading to water leakage. The roof prefabricated panels may develop cracks due to long-term pressure and temperature changes, allowing rainwater to seep into the house through these cracks. When the walls are subjected to external forces or the influence of foundation settlement, cracks may also appear, causing rainwater to penetrate. If the floor deforms due to moisture or foundation problems, its waterproofing performance will be compromised, triggering water leakage issues.
