Concrete Cracking: Why You Might Be Experiencing The Issue

Construction & Contractors Blog

Concrete cracking is an unfortunately common occurrence. However, make sure you remember that common and normal are not one and the same. A crack in a concrete patio, floor, or other surface is an indication of a problem — a problem that you need to address. Learn about some of the typical reasons why concrete cracks so that you can get a better idea of why you might be dealing with the problem.

Too Much Water

Concrete requires the right ratio between the aggregate mixture and water. However, many non-experienced people don't quite get the balance right. When mixed correctly, the concrete mix tends to be on the thicker side, which makes it harder to apply. 

Some people eliminate this challenge by adding more water to the mixture to make it more pliable. However, too much water weakens the mixture and makes it more prone to damage once it dries and settles. Keep in mind, the water should be added slowly to the mix, not all at once, to prevent adding too much water.  

Poor Weather Conditions

Concrete is durable and can withstand all types of weather elements, but only once it's set. During the application process, the concrete mixture is very vulnerable to weather conditions, and weather extremes should be avoided. In heat extremes, the top layer of the concrete will dry too quickly. 

Since concrete contracts when it dries, you'll have a top layer that is shrinking and a bottom layer that is staying the same. The imbalance could cause the dried parts to crack. In cold weather, the concrete will dry slower. The slow drying process could cause the concrete to shift before it dries and firms, which could create irregularities.

Lack of Support

Concrete is strong on its own, yet, it does require a support system that comes in the form of control joints. The primary function of control joints is to prevent cracking. A common amateur mistake is not realizing that merely adding control joints is not enough.

You need to add the right number of concrete joints, and even more important, in the correct location if you want to minimize cracking. Without addressing these factors, the concrete surface will still have weak areas, which will make it vulnerable to cracking. 

Speak with a concrete contractor if you are experiencing a problem with cracking. A concrete contractor can assess the damage, determine the cause, and repair the surface as soon as possible.
