Reasons Why Your Pool Deck Deteriorate | You’ll Probably Need a Pool Deck Restoration

Natural and man-made causes are two main reasons why your pool deck deteriorates. That and aside from the constant wearing when the swimming pools are in used, pool decrease in quality due to poor maintenance.

Today’s article discusses the common reasons why pool decks get damaged and see if you qualify for a pool deck restoration.

Pool Deck Restoration: Five Reasons that Tells You It’s Time

The most common of all types of pool deck damage are primarily man-made. There is so much more that is going on with the constant wear and tear. As long as there is a pool to splash in, anyone will be ready to dive. It does not also save the concrete from seasons when summer is not yet around. 

Case 1- Faulty Installation

It’s not summer’s fault. Even though it’s out of season, a swimming pool’s deck may weaken when the materials used and installation do not follow the proper procedures. In this case, it’s up to the hands that build the decks.


You will not have to do anything if a faulty installation takes place. Here are specific conditions of faulty installation. 


  • Improper placement of structural reinforcement
  • The concrete mix did not cure on time
  • Lack of flooring preparation
  • Wrong consistency
  • Substandard materials used

Case 2- Inconsistent concrete mix

Now with case number two, let’s focus on one specific reason related to faulty installation. It’s the consistency of the concrete mix used. Concrete costs don’t come cheap, so you have to make sure you have to get this one right. 

Under this case, there are two reasons:

You will see this condition often with stamped overlays added to the pool deckings. What happens here is that the overlay mix is too thin or too thick. 

Look closer at these reasons:

a) The concrete mix is too thick

An overlay will have a different consistency from the existing concrete. It needs to be thicker, but making it too thick will instantly cause cracks on the concrete. It is due to the pasty and heavy mass over the existing concrete.

b) The mix is too thin

On the same note, it will be hard to cure in time when the concrete mix is too thin. When it takes too quickly for the overlay to dry outside, it is still probably damp on the inside. This can cause cracks. Even if no one is yet using the decks, the slab will begin to crack or crumble.

Sometimes, an installer may use the best tools, work with the best skill, and be precise enough to install the concrete decks. 

However, the main culprit for the decks’ declining features is the inconsistency of the materials used.

The best option here is to reach out to a concrete contractor San Diego expert. 


Case 3- No sealing applied

Concrete decks require the use of concrete sealers. These are thin film coats used to protect the surface, especially for exterior floors. 

A concrete surface needs to be sealed, especially if it’s on the swimming pool’s decks. Water constantly hits the surface, and water will hasten the damage if the surface is not waterproofed through sealing.

Case 4- Discoloration

The last reason in this list will have something to do with the water and the chemical components. First, water alkalinity may contain too much chlorine. These compounds will react with the decking’s surface and may cause yellow stains or whitish stains.

Second is damage to the pool flooring or the pool shell: If there is an existing crack or dent font the base of the swimming pool’s basin, mud, and soil will make the water cloudy and murky. Murky water that splashes onto the decks will cause hard to remove dark stains on the surface.
