These cracks not only affect the beauty of the building, but more importantly, they may pose a threat to the structural safety of the building. For example, thermal expansion and contraction caused by temperature changes may cause stress in wall materials, resulting in cracks; while uneven settlement of the foundation may cause cracks of varying degrees in the structure. In addition, improper operations during the construction process, such as uneven concrete pouring and improper maintenance, are also common causes of cracks.

[0003] Common methods of repairing cracks in building walls on the market include using caulking agents, sealants, structural reinforcement, etc. However, simply filling cracks cannot solve the problem of crack expansion. In the long run, it may lead to a decline in the overall safety of the building, or even cause partial or complete collapse of the building, bringing serious safety hazards and economic losses.
