oncrete structures are known for their durability and classic appearance. But the caveat here is an owner of a concrete floor or patio has to be vigilant enough to detect cracks. Specifically, before it develops into something nastier.

Preventing concrete cracks is all about minimizing the chances of its development in the first place.

As a matter of fact, there are many causes due to which a concrete structure can develop unsightly cracks. The best solution seems to be contacting a local concrete repair and maintenance company to get it fixed on time.

Previous experience tells us not taking preliminary steps to Avoid Concrete Cracks can manifest itself through more damage. And the result is always visible in the appearance of the concrete surface.

You don’t want that. Right?

This leaves us with only one sensible choice and that’s to first understand the causes behind concrete cracks. This makes preventing concrete cracks easier and faster as well.

Let’s hop in and see what are the leading causes behind crack development in concrete and what you can do about it.


What Causes of Concrete Cracks?

The most common cause of concrete cracks is drying shrinkage. Concrete, as it sets, has an innate tendency to shrink.

Another thing to keep in mind is concrete’s low tensile strength. What this means is cracks become unavoidable when the inner tensile tension exceeds the tensile strength of the concrete.

Well, you’ve to first recognize the factors predominantly responsible for this phenomenon. Understanding the below-mentioned causes can help you to Stop Concrete from Cracking.

Not to mention, you’ll be able to take preventative measures to prevent cracks in the first place.

#1. Lack of Sub-Grade Preparation

A sub-grade should be smooth and have proper drainage. The absence of this means the concrete will lack the support as it shrinks. This automatically increases the chance of cracking.

#2. Excess Water in the Concrete Mix

It’s paramount to choose the right concrete mix before application. Excess water in the mix evaporates leading to more shrinkage. Thus, making it hard to Prevent Concrete Floor Cracking.

#3. Improper Curing

Usually, a Concrete Pumping Company apply a curing compound after placing the concrete. However, not allowing the required time for the concrete to cure can lead to damage in the surface later on.

So, these were the leading causes behind concrete damage. In the next section, we’ll be taking a look at some of the measures you can take for Preventing Cracks in Polished Concrete Floors and other structures


Preventing Concrete Cracks For A Smooth Surface 

Following are some of the factors that play a huge role when it comes to preventing concrete cracks from spreading.

Moreover, taking care of these factors proves to be useful in Preventing Concrete from Cracking in the future.

#1. Depth of the Contraction Joints

Concrete contractors need to pay extra attention when jointing the concrete. This helps in dictating where the concrete will crack, which, by the way, is far better than random cracking.

Extra care is a must to maintain the depth of the concrete contraction joints. Based on a general estimation, concrete joints should be 1/4th of the slab thickness.

NOTE: Ensure that the edges are not worn if using a hand tool to joint the concrete. This will play a major role in Preventing Cracks in Concrete.

#2. Timing of the Joints

Another main cause for crack development in concrete is not jointing them quickly. Placing hardboard or plastic preformed strip in the concrete on time helps in preventing concrete cracks.

Moreover, ensure that these strips are in proper alignment and are not skewed. Contractors should take special care when using a saw to cut the joints. You need to cut it as soon as the concrete can take the sawing.

It’s better to saw cut the concrete within the first 6 to 18 hours without waiting any longer. This is, in fact, essential to prevent random cracks in concrete.

#3. Proper Sealing of the Joints

Now, this one is an absolute necessity. Using a sealant significantly lowers the chances of surface water infiltration. This can play a big role to prevent damage to the sub-grade layer.

Sealing helps in the expansion and contraction of the concrete without cracking. This translates to better strength in the long-term. This is why contractors usually use sealant even if it’s not mandatory.

NOTE: Apply sealant only after the completion of concrete shrinkage.

#4. Curing of the Concrete

Proper curing can never be ignored. In fact, attempts are made to prolong the curing process by maintaining the moist condition of newly placed concrete.

Continuous spraying and wet coverings are useful in moist curing. Remember to use a wet covering only after the surface has hardened sufficiently. This will help to prevent any further damage to the surface.

A film of water should remain on the surface throughout the curing process to ensure the durability of the structure.

Well, a professional contractor is indispensable to ensure proper application of all these steps.
