\n\t\t\t

A: Generally, if the ceiling of the elevator room in the top floor of a residential building experiences a leak, because the water storage tank is located above it, the first thought is that it is probably caused by a water tank leak; however, it must be noted that the water tank is located in the basement of the building.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t

\n\t\t\t

Answer: (i) In the process of waterproofing the tank, the most common mistake made on construction sites is to first paint the base and then apply the waterproofing coating. The reason is that since tanks are generally prone to leakage, it is necessary to first seal the base before applying the coating.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t

\n\t\t\t\n\t\t\t\t(One Hundred Questions on Waterproofing) #83: In some cases, the waterproof coating is only applied by brushing with seven-millimeter quartz powder or by buying some waterproof agent at a hardware store; there is no leakage phenomenon. On the other hand, some construction sites use expensive imported materials from Europe and the United States, but they often leak, and repeated repairs are ineffective. Why is that?\t\t\t<\/a>\n\t\t<\/h3>\n\t\t\t\t
\n\t\t\t

Answer: The key lies in the structure of the tank; as in question 83, ninety percent of the water leakage is due to four major defects in the structure; if these defects are properly addressed, a simple 1:2 countermeasure can be applied.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t
