What to Do If a Container House Sprinkles Water
If a container house sprinkles water (leaks), appropriate measures such as emergency handling, long-term maintenance, and daily upkeep should be taken based on the situation, and evidence should be retained for rights protection.

Emergency Handling
Upon discovering a leak, immediately lay waterproof cloth or plastic film above the leak point and secure the edges with heavy objects to prevent further rainwater infiltration. If the leak is caused by cracks or small holes, use waterproof coating for temporary repairs to minimize losses.
Long-term Prevention and Maintenance
- During the Warranty Period: According to the 'Regulations on the Quality Management of Construction Projects', the minimum warranty period for roof waterproofing projects is 5 years. If a leak occurs during the warranty period, promptly notify the developer or seller in writing and request them to fulfill their warranty obligations for free repairs. If the developer delays or refuses, you may carry out repairs yourself or commission a third party, with the costs borne by the developer. You may also claim compensation for other losses and resort to legal means if negotiation fails.
- After the Warranty Period: You will need to bear the repair responsibilities yourself. Choose a qualified and reputable repair company and sign a detailed repair contract. If the leased container house leaks due to reasons not attributable to the tenant, the tenant should promptly notify the lessor for repairs. If the lessor fails to fulfill their obligations, the tenant may carry out repairs themselves, with the costs borne by the lessor.
Specific Repair Methods
- Using Waterproof Coating: Select professional waterproof coatings such as polyurethane or epoxy resin and apply them evenly to the leaky area, paying special attention to covering cracks or aged parts. This method is suitable for small cracks or local repairs.
- Using Waterproof Membrane: First, clean the base layer, lay modified asphalt membrane, and fix it with adhesive. Then, conduct a water storage test to ensure the waterproofing effect. This method is suitable for large-area leaks or structural joints.
- Reinforcing with Covering Materials: Install steel structure keels and then cover them with materials such as color steel plates, aluminum plates, or glass, combined with adhesive treatment. This method provides both waterproofing and thermal insulation and is suitable for overall roof renovation.
- Using Sealant or Glass Glue: For minor local leaks, such as small cracks at welding points, use sealant or glass glue for temporary repairs.
- Welding Repair: If the container is made of metal and the leak point is small, it is recommended to use argon arc welding for repairs to avoid deformation caused by electric welding.
Daily Maintenance and Evidence Retention
Regularly inspect the container house, especially the roof, exterior walls, and other leak-prone areas, and promptly repair any issues found. Clear debris from drainage pipes and gutters to keep the drainage system unobstructed. Upon discovering a leak, take photos or videos immediately as evidence, record the leak situation and time, and retain communication records with the developer, repair company, or lessor for subsequent rights protection purposes.
