At 11 o'clock on the evening of August 12, an explosion occurred in the Tanggu Development Zone in Tianjin, and the scene was on fire. As of the 14th, the explosion caused a total of 55 deaths; 701 hospitalizations. According to the China Seismological Network, from the waveform record results, the first explosion occurred at 23:34:6 on August 12, and the near-seismic magnitude ML was about 2.3, equivalent to 3 tons of TNT, and the second explosion occurred. After 30 seconds, the near-seismic magnitude ML is about 2.3, which is equivalent to 21 tons of TNT.

After the shock, the original wall of the house and the new brick wall are not tightly attached due to the vibration, and loose, falling off, empty drums or staggered seams appear. The use of an empty drum hammer and a protractor is used for correction, and the frequency of supervision inspections is doubled and continues for one week.

After the shock, the base layer of the wall must be checked for cracks and cracks as soon as possible. If there is a crack, the base layer of the original wall is removed along 3 cm to 5 cm around the crack, and the wall expansion joint is used for the reinforcement of the net.

The waterproof layer of the decoration is prone to cracking after the shock, especially the cold coating and waterproofing process of the cement mortar is more prone to problems. Due to the good ductility of the coil, the general vibration does not affect the existing waterproofing. Compared with other asphalt-based waterproof materials, it is a flexible waterproof coating, which is not easy to cause damage during vibration. The main advantage of the flexible waterproof roof is that it has better adaptability to the settlement of the foundation of the house and the vibration or temperature of the house. Therefore, it is recommended to use asphalt-based waterproof coating in areas prone to the above problems.
