Are there cracks in your concrete? If you’re reading this, you may be wondering what to do. In this blog article, we’re going to take a look at why cracks in concrete occur and when you might need to invest in concrete repairs.

How do cracks in concrete happen?

Cracks may start to appear in your concrete structure for a number of reasons. Among the most common include cracks caused by plastic shrinkage, expansion cracks, cracks caused by heaving and settling and those which appear as a result of premature drying.

For certain types of cracks and certainly the more severe, you will need to invest in a concrete repairing solution.

Why do I need to repair these concrete cracks?

In quite a lot of cases, cracked concrete is merely a cosmetic issue. It’s actually quite a common issue when concrete dries. If you leave the cracks as they are, then you might not be risking long-term damage to your building. But do you really want to take that risk?

Some cases of concrete cracking may be more severe. Take structural cracking, for example. The pressure exerted on a building is controlled by outside influences such as the wind. Over time, pressure will build up in certain points of the structure, causing cracking. If the cracks spread too wide, then this could create long-term structural damage in your building.

Concrete cracking is also a particular issue if the cracks widen beyond a certain diameter. More than three millimeters and you could risk water seeping into the wall. This could rust any steel inside supporting walls and further weaken the area around the cracks, or, if the crack occurs during winter, you could risk the water freezing into ice. This could expand and further put pressure on the wall.
