The disadvantages of aerated concrete include the fact that for a certain period in the pores, water accumulates, so you need to protect the walls from the exposure of the environment using waterproofing. Otherwise, the structure will collapse over time. Also, this material does not take out a large load, as a result of which it gives cracks. Therefore, aerated concrete is more often used in low -rise construction. It is recommended to use a reinforced belt when erecting walls from aerated concrete.
