How long is the shelf life if the inner wall is cracked?

Hello! The problem of cracks needs a lifetime warranty, but it depends on the width of cracks. In the national building code, it is clearly marked that cracks larger than 0.3mm belong to harmful cracks, mainly considering that water leakage after corrosion of steel bars will affect the durability of buildings.

But a little repair won't affect the integrity. If the property or construction unit is responsible for the maintenance, and the correct method is selected for maintenance, it will not affect the normal use.
