How to deal with cracks in building columns;

1. First, observe the width of the crack in the column. If the width of the column crack is less than 0.2mm, this phenomenon is normal within the range allowed by the design, and it can be left untreated. Later, we will continue to observe whether there are signs of expansion and extension of cracks, and then make plans.

2. If the crack width is in the range of 0.2~0.5mm, and the crack is slightly larger, you can find a construction worker who specializes in repairing the wall column crack to repair it. It is better to find an old master with many years of experience.

3. But if the crack width of the column looks large, it means that the problem is serious and the design is safe. Then measures should be taken to remedy and strengthen, and the treatment methods are different according to different types of houses.

4. If it is a self-built house, it is necessary to find a professional civil engineer in this field to analyze the causes of cracks, such as uneven settlement, temperature change and improper use of materials. , and then take concrete reinforcement remedial measures according to specific reasons, such as grouting.

5. If the house is a residential area in the city, there is usually a property. You can find the property to reflect, or directly find the developer, because the purchase contract has already stated the developer's warranty responsibility and duration for the house. The developer will contact the construction unit that built the building at that time for warranty.

6. The problem of cracks in building columns seems simple, but the reasons are complicated. If you are not a professional in this field, don't act on your own, thinking that you can just wipe some cement mortar. After all, safety comes first and life comes first.
