How many years does the external wall brick fall off?

In the residential area where Bian Xiao lives, banners were hung in some conspicuous places, which read, "Pay attention to the external wall falling off, and people and vehicles are forbidden to stay here". In recent years, falling accidents occur frequently, and residential property companies also use various publicity methods to remind people to prevent the external wall from falling off and people from smashing cars. But the key question is, how many years does the exterior wall tile fall off? Today, Bian Xiao will talk to you about the shelf life of the external wall tiles in the community.

1. What's the shelf life of exterior wall tiles?

According to the commercial housing management regulations, the shelf life of exterior wall tiles is generally five years, and the specific date should be calculated from the date of acceptance.

After the completion of the project, the quality can not meet the relevant requirements, you can ask the employer to rework and repair at the same time. If there are some losses, it should also be compensated by the developer. If the circumstances are serious, the developer will be suspended for rectification, and at the same time, his qualification will be lowered or even his qualification certificate will be revoked. This also reminds developers to pay attention to the quality of the project during construction to avoid falling off in the future.

Second, the reason why the tiles on the outer wall of the residential area fall off

1. When painting tiles, if the adhesion of cement mortar fails to meet the requirements, the tiles will fall off later.

2. When tiling, the wall surface is not treated. For example, if the wall is dry or uneven, the tiles will be empty and eventually fall off.

3. The construction did not follow a certain process. For example, if the wall is not wetted by water first, the cement mortar will set faster, the cohesive force will drop, and the cement brick will fall off later.

4. It is also possible that the selected materials are unqualified. For example, the quality of cement and yellow sand is unqualified or the mixing ratio does not meet the requirements when mixing, resulting in loose tiles.

Bian Xiao concluded: It is definitely not a trivial matter for the tiles in the residential area to loosen and fall off. If someone passes by or stops the car downstairs, it is likely to cause some losses and serious casualties. Therefore, developers are also required to ensure quality and quantity when building houses, and can only deliver them after acceptance.
