What to Do If a Container House Leaks

When a container house leaks, follow these steps to handle it:

I. Determine the Cause of the Leak and the Responsible Party Observe and conduct professional assessments to identify the cause of the leak, which may include quality issues with the container itself (such as metal corrosion or weld defects), improper installation (such as inadequate joint sealing or drainage system design flaws), or human-induced damage during use (such as external impacts or unauthorized modifications). Based on the cause, determine the responsible party: if the leak is due to manufacturing defects in the container, the supplier is responsible; if it is caused by installation team errors, the installer is responsible; if it results from improper maintenance or modifications by the user, the user bears the responsibility.

II. Collect Evidence Take photos and videos of the leak location, extent, and internal damage (such as mold on walls or soaked items), ensuring the images are clear and include timestamps. Keep documents such as the container purchase contract, installation contract, invoices, and quality inspection reports as evidence for future rights protection.

III. Take Targeted Remedial Measures

• Small cracks or local repairs: Apply polyurethane or epoxy resin waterproof coatings evenly to the leak area, focusing on covering gaps and aged parts, and perform regular maintenance; or use sealant/glass glue to temporarily fill small gaps at welds, which is easy to operate but requires subsequent reinforcement.
• Large-scale leakage or structural joints: After cleaning the base layer, lay modified bitumen waterproof membranes, secure them with adhesive, and conduct a water storage test; if the metal container has small leak points, use argon arc welding for repairs to avoid deformation caused by electric welding.
• Overall roof renovation: Install steel structural keels and cover them with color-coated steel sheets, aluminum sheets, or glass, combined with adhesive treatment for both waterproofing and thermal insulation.
• Auxiliary measures: Use activated carbon to absorb internal moisture, preventing condensation and mold growth; regularly inspect the drainage system, clear accumulated water and debris, and avoid excessive pressure on the roof.

IV. Communicate and Negotiate Promptly Based on the responsibility determination, contact the supplier or installation team, inform them of the leak situation in writing or orally, and request them to inspect the site and develop a repair plan, specifying the repair timeline and quality assurance terms. If the contract includes clear liability clauses, you can claim repairs or compensation accordingly.

V. Seek Legal Recourse If negotiations fail, entrust a lawyer to send a lawyer's letter to the responsible party, formally requesting compensation; if there is still no response, file a lawsuit in court, submitting evidence (such as leak photos, contracts, and inspection reports) to demand that the responsible party bear repair costs, compensation for property damage, and other liabilities.
