Does not affect the stress.
Aerated block wall is mainly filled with material, which does not bear the main load, and pouring polyurethane has no effect on its stress.
Perfect integration
Polyurethane and aerated block are perfectly integrated, which will not produce chemical reaction and ensure that the original performance of aerated block will not be destroyed.
high stability
The thermal stability and volume variability of polyurethane are very stable, which can perfectly fill the cracks and make the wall look brand-new.
multiple-choice
In addition to polyurethane, gypsum, putty, mortar and other materials can also be selected to fill the gap. However, please note that before repairing cracks, we must first analyze the causes of cracks, so as to fundamentally solve the problem.
Analyze the reasons
There may be many reasons for the cracking of the aerated block wall, such as the disturbance of the building structure, the expansion or contraction of the aerated block due to water absorption, and the quality problems of the aerated block itself. If there are continuous or patches of cracks on the wall, it is likely to be caused by structural deformation, and the problem needs to be solved from the root.
