5 Reasons Your Concrete Pool Deck is Cracking

Are cracks on the concrete pool deck normal? Before you call on a Pool Deck Repair Newport Beach, CA, to treat those, you must identify what causes them. 

An indispensable truth about the concrete floor is that cracks are natural. Thin, hairline creases would appear on any concrete surface. However, those flaws are typical and would not cause concerning damage. A concrete sealer is the best treatment to prevent those normal cracks from turning into someone’s problem.

So, when should you worry about those cracks? What may have caused them? What signs do we need to look out for before we can do pool deck resurfacing? How will we know if pool deck repair is necessary? Find out those in today’s blog. Here is why creases and lines appear on the surface of the concrete pool decks.

  1. Seasonal Problems (Winter & Summer Mostly)
  2. Expansive Soils
  3. Poor Compaction
  4. Not Sealing Cracks
  5. Weakened Concrete

Why Do Concrete Pool Deck Cracks?

The temperature change is the natural cause of thin breakouts on concrete surfaces. Learn more about it in the first reason we have for this list.

1. Seasonal Problems

Contraction and expansion cause the ground to move, and since concrete is not a flexible material, it is prone to cracking. The movement of the earth is a natural phenomenon that happens when the seasons change from summer to winter. 

But expert concrete installers already know this condition. And to aid in this situation, they devised a way to prevent the severe impact on the floor material, using expansion joints. This is one way to have the pool deck resurfaced.

The next point is also related to this.

2. Expansive Soils 

Sometimes soil underground naturally moves. Aside from temperature change, expansive soils are always in subtle motions due to the gravity and rotation of the earth. This is another natural phenomenon that no man can control, and this condition creates concrete expansion gaps that may not be suitable enough. 

There are more specific solutions for these causes of damage. It is best to get in touch with a local concrete contractor who would recommend the best approach for this.

3. Poor Compaction

Concrete compaction is how dense the slab is. Concrete density tells how strong and resistant it would be. 

For example, you want to ensure that the floors would not break or crack when a massive object contacts or hits the surface. So, what if the concrete pool deck got poor compaction?

Poor compaction means holes and gaps inside the cement material caused by air bubbles as the cement cures. This happens when not enough force or weight is pressed onto the curing slabs, leaving air bubbles. Those small hollow parts make the concrete pool deck susceptible to breaking and cracking.

4. Not Sealing the Cracks

Of course, a pressing reason why cracks on pool decks persist is not sealing them. This might happen when you mistake problematic creases for the normal thin ones. 

You have to learn how to identify the cracks in the pool deck surface next time you browse our blogs. How can you tell if pool deck cracks would lead to a severe problem?

5. Weakened Concrete

Go back to all of what is mentioned above. If you fail to prevent them, it leads to concrete failure. 

Plus, consider the worst when you know you got an old pool deck or have already reached its age limit. With this condition, the concrete floor is starting to get weak, and any exposure to damages would only lead to severe cracks and breaking. This entails that you need pool deck repair.
