1. How Concrete Pools Pop

Concrete pools are not immune to certain issues like shifting or settling. When pressure pressure from groundwater builds up beneath the pool, it can put too much stress on the rigid concrete shell. In some cases, the pool can actually “pop” out of the ground or shift position.

Concrete pools lack the flexibility of fiberglass, so when pressure builds up beneath the surface, they can crack, lift, or shift in unpredictable ways. This usually happens if the pool is installed in an area with a high water table or improper drainage.

While fiberglass pools can also pop, it is much harder for them to crack when doing so. So you can reset a fiberglass pool for far less money than a concrete pool. Concrete pools usually need to be demolished after popping.

2. The Cost When a Concrete Pool Pops

When a concrete pool pops, it’s not just a cosmetic issue, it becomes a major financial burden. Repairing a popped pool can be expensive. You’ll likely need to drain the pool, fix any structural damage, and re-level the pool. In some cases, the pool might require a complete rebuild. It’s a costly, time-consuming fix that’s best avoided.

3. Fiberglass Pools: Stability and Strength

Our fiberglass pools are built with a single-piece molded shells making it more flexible and can handle shifting groundwater or pressure more effectively. The rigid, custom-built design of concrete pools leaves them vulnerable to damage. Pettit Pools also pours an eight inch by ten inch concrete with fiber mesh footer/apron around the pool coping to help lock it in place. 

Fiberglass pools also come with pre-installed plumbing, which reduces the need for backfilling and minimizes the risk of pressure buildup. Their strong and flexible design means you’re less likely to experience any shifting or lifting, giving you peace of mind.

4. Why Fiberglass Pools Are the Better Choice

• Less Risk of Damage: The flexible, one-piece shell of fiberglass pools stands up to water pressure better, making them far less likely to pop out of the ground or crack.
• Faster Installation: Fiberglass pools are pre-fabricated, meaning installation takes far less time than building a concrete pool. No need for complex construction or curing time.
• Lower Maintenance: Thanks to their smooth surface, fiberglass pools resist algae growth, making maintenance easier. With fewer chances of shifting or cracking, you’ll spend less time and money on repairs.
• Cost-Effective: While fiberglass pools can cost more upfront, their long-term savings on maintenance, repairs, and water bills make them the smarter investment. The risk of issues like popping is minimal, saving you money over time.

5. Conclusion: Keep Your Pool Where It Belongs

Concrete pools may offer customization, but the cost if they do pop or crack, in our opinion makes it a terrible choice to your backyard.  Choose fiberglass for a stable, hassle-free pool that will last for years to come.
