What's the matter with the leakage of steel bars upstairs and rusting in Aiding County Community?

The leakage rate of building roofs in China is about 95%, and the severity varies, some are acceptable, and some are seriously leaking after repeated maintenance.

China stipulates that the waterproof warranty period is five years. From the date of completion and acceptance, developers have no incentive to make good use of materials, and the same is true for finding property maintenance in the future.

If you want to be completely waterproof in the future, you should do it yourself and redo the waterproof layer with urea-based waterproof coating.
