Think about it, why do you want to reinforce it? It must have scratches, cracks or leaks. But these phenomena still happen. Can you get it back? That's impossible! The existing gaps are not tightly blocked, and you can't bear strong or local pressure. You can only fool your eyes and comfort your spirit on the surface. This is what we can do. It is impossible to crack it or not! It is also temporary to think that what has broken will no longer develop.
Therefore, the building must be planned, designed and built first. Once something goes wrong, it cannot be reversed!
