What is the cause of the leakage of the living container mobile house?

1. During the installation and use of the movable room, or trampling on the roof leads to the loosening of the fasteners, and the aging of the waterproof pads of the fasteners causes water leakage at the fasteners.

2. Unreasonable selection of waterproof materials and aging in the construction process of residential container prefabs.

3. Opening holes on the panel of the movable room, and installing various types of fans, exhaust pipes, etc. around the cracks, the waterproof treatment is not good; the movable room is in use due to the influence of external conditions, wind load, snow load, thermal expansion and contraction. When the deformation of the roof panel is formed, the cracks at the lap joints expand, and the original waterproof treatment is destroyed, resulting in water leakage.

4. There is no horizontal slope in the gutter of the container mobile house, and the design of the gutter downspout is unreasonable. In the event of heavy rain, the gutter water can not be discharged to the gutter and return to the gutter; During construction, the anti-corrosion of the gutter is not in place, which leads to rust and erosion of the gutter, or dregs and other conditions such as clogging the drain, which may cause water leakage or water backflow.
