Concrete Cracks: What causes them and How to Prevent them
Concrete lasts longer compared to other building materials, such as gravel, as it is weatherproof and resistant to erosion. It might develop cracks, scaling or pitting because of the method of curing as well as various environmental factors. Cracks can make your concrete structures appear unattractive and that’s where the importance of commercial concrete repairs comes into the picture.

In this blog post, we discuss concrete cracks and how to prevent them.
Cracks are common in almost all forms of concrete surfaces. There are several causes, which includes:
- Excess water
Concrete shrinks as it hardens and dries. This is mainly due to the evaporation of the excess water in the mix. The shrinkage can force the concrete to pull apart resulting in the formation of cracks.
Know the amount of water that is to be poured for the mix. Ensure you have selected a reputable contractor, who has the experience to make a proper mix.
- Rapid drying
- Poor sub-grade preparation
A smooth sub-grade can prevent any restraint when the concrete shrinks and reducethe chances of cracking.
- Improper curing
If the concrete surface loses moisture quickly, it will lead to a condition called map cracking. This condition does not affect the concrete’s structural integrity. In certain cases, a lack of curing can result in more severe cracking.
It is recommended to actively cure concrete to improve the overall integrity and prevent surface defects.
- Lack of control joints
The joints placed should be equal to the slab’s depth and not more than two-three feet of the concrete’s thickness.
