I am a property management dispatcher. Recently, I have received many complaints from residents on the top floor about water leakage. Because it is a jade board building, a lot of manpower and material resources are installed every year. Since the problem can't be solved by the normal leak-patching method, I suggest you use this method: buy a rubber pad in a sulfuric acid tank, the specification is: length 100 m x width 3.3 m (thickness 5 mm)! The rubber mat on the roof can ensure no water leakage for more than 30 years! This is how the business center I manage and the building rented by China CITIC Bank solve the water leakage problem!
