Decoding Pool Cracks: How to Tell if a Pool Crack is Structural

Owning a pool is a source of joy and relaxation. But every pool owner dreads the sight of cracks in their swimming pool. Not all cracks are created equal, and understanding the difference can be crucial. Specifically, it’s important to distinguish whether a crack is simply superficial or if it’s indicative of underlying structural damage. In this article, we will delve into how to tell if a pool crack is structural.

The Types of Pool Cracks

Pool cracks typically fall into one of two categories: surface cracks and structural cracks. Surface cracks are generally minor, often resulting from changes in temperature or natural settling over time. These hairline fractures can be unsightly, but they don’t pose a threat to the overall integrity of your pool. On the other hand, structural cracks are serious issues that can compromise the stability and safety of your swimming pool.

Identifying Structural Cracks

So, how can you tell if a pool crack is structural? Here are some tell-tale signs:

  1. Depth and Width: Structural cracks tend to be deeper and wider than surface cracks. If the crack penetrates the shell of the pool and extends into the concrete, it’s most likely structural. It might even span the entire depth of the pool wall or floor.
  2. Location: While cracks can appear anywhere, structural cracks are often found in the corners or along the bottom of the pool where the pressure is greatest.
  3. Leaking Water: One of the most alarming signs of a structural crack is water loss. If you notice your pool’s water level dropping more than the usual rate of evaporation (approximately 1/4 inch per day in peak summer months), there could be a structural issue at play.
  4. Damage to Surrounding Area: Structural damage can often affect the area surrounding your pool. Look for signs like soil erosion, sinking deck, or shifted pavers, which may indicate a structural crack in your pool.

What Causes Structural Cracks?

Structural cracks can result from several factors. Poor construction techniques, inadequate structural design, or substandard materials can lead to such issues. Additionally, external forces like ground movement, freeze-thaw cycles, or even the weight of the water itself can cause structural damage over time.

What to Do If You Suspect a Structural Crack?

If you suspect a structural crack in your pool, it’s crucial to act promptly. Ignoring the issue can lead to more severe damage and costly repairs down the line.

Start by marking the ends of the crack with a waterproof marker and monitor any changes. If the crack continues to grow, it’s likely structural.

At this point, it’s advisable to seek professional help. Pool repair specialists have the necessary tools and expertise to accurately diagnose and repair structural damage. Riviera Pools of Dallas, for instance, provides professional cracks and structural repair services, ensuring your pool remains safe and enjoyable.

Remember, it’s not just about fixing the visible damage. It’s essential to address the root cause of the problem to prevent recurring issues. This might involve improving the drainage around your pool, addressing soil instability, or reinforcing the pool structure.

Prevention is Key

While it’s crucial to know how to identify structural cracks, prevention is always better than cure. Regular pool inspections can help catch potential problems early before they escalate. Consider enlisting professional pool maintenance services, which typically include routine checks for signs of structural damage.

In conclusion, understanding the difference between surface and structural cracks can help you maintain the safety and longevity of your pool. If in doubt, always consult with a professional to ensure the structural integrity of your swimming pool. Ignoring structural damage not only compromises the safety of your pool but also can lead to expensive repairs.
