8 Common Factors That Lead to Concrete Cracks

When it comes to the longevity and aesthetics of your concrete curbs and sidewalks, understanding what causes them to crack is crucial. Numerous factors can lead to concrete woes, but keeping these potential problems in check will ensure your concrete structures remain in top condition for years to come. Bonness explains some of these factors below:

1. Excessive Load

While your concrete structures might seem indestructible, they can only withstand so much. Putting excessive load on your concrete paving can lead to cracks. Ensure you’re distributing weight evenly wherever possible to increase the lifespan of your concrete.

2. Thermal Contraction and Expansion

Living in Naples, FL, means experiencing various temperature shifts. Did you know that these changes cause your concrete to expand and contract? This constant shifting, especially when drastic, can cause cracks to form over time.

3. Incorrectly Placed Joints

Concrete joints must be strategically placed to provide structure and strength to the overall forms while, at the same time, reducing the unnecessary load on the concrete. If they are not placed correctly, it can strain the concrete and lead to cracking.  

4. Rapid Drying

If your driveway construction project dries too quickly, you might have to deal with weaker concrete prone to cracking. Ensuring the correct mix type and conditions helps prevent this issue from occurring.

5. Corrosion of Reinforcements

Concrete is usually reinforced with steel bars. However, these can corrode over time. This corrosion expands the steel, pushing against the concrete and causing cracks.

6. Damage From Roots

Love those big, beautiful trees in your yard? Be careful. Their roots can wind their way underneath your concrete structures, pushing up against them and causing cracks.

7. Concrete Shrinkage

As concrete dries, it naturally tends to shrink a little. Although common and expected, if not properly controlled, this shrinkage can lead to surface cracks.

8. Improper Strength

Different construction projects require different strengths of concrete. Using the improper strength can lead to cracks and heightened vulnerability. Reputable contractors are well-versed in matching the right concrete strength with your project’s requirements.
