A sudden large drop in temperatures caused floors to buckle and break homes in southern China.

Video showed that, due to the sudden drop in temperature, one resident in Guangzhou witnessing the floor of their home floor buckling and cracking.

It’s reported that with the influence of a southward-moving cold front, Guangzhou experiences a severe cold snap. On December 24th, Guangzhou recorded its lowest temperature of 3.2°C, breaking the record for the lowest temperature in the second half of the year.

The homeowner, after posting the video of the floor buckling online, received feedback from many Guangdong residents reporting similar issues. According to a professional specializing in repairing hollow tiles, he has been overwhelmed with calls in recent days, all reporting issues of tiles bulging.

The abrupt winter temperature drop, coupled with indoor heating from air conditioners or heaters, causes thermal expansion and contraction in tiles. This phenomenon leads to adjacent tiles being compressed by the walls, resulting in warping and even cracking. In some cases, improper cement mixing during tile installation can also contribute to tile buckling during winter.

据一名做瓷板空鼓修复的专业人士介绍，他这几天电话都接不过来了，都是反映瓷砖拱起来了。由于冬天气温突然降低，这个时候室内会使用空调或暖气，由于温度突然升高，瓷砖会出现热胀冷缩的现象，导致周围的瓷砖受到墙体挤压，出现翘起、甚至是炸裂的现象。还有可能是铺贴瓷砖时，水泥的配比没有按照相应的标准调配，导致冬天出现瓷砖翘起的现象。
