Can You Install an Above Ground Fiberglass Swimming Pool?

At Pool Stop Online, we understand the allure of swimming pools that offer both durability and aesthetic appeal. While most people associate fiberglass pools with in-ground installations, above ground fiberglass swimming pools provide a unique solution for homeowners seeking flexibility in design and functionality. However, it’s important to note that fiberglass pools are typically installed partially above ground rather than entirely above ground due to the material's characteristics.

Here’s a comprehensive guide on above ground fiberglass swimming pools, what they are, and how they can be a fantastic option for your home.

What is Fiberglass?

Fiberglass is exactly what its name suggests—thin fibers of glass woven together. The material is commonly used to reinforce objects and structures, providing enhanced durability while maintaining a lightweight composition. Fiberglass fibers are often arranged in a basket-like weave, laid on a sturdy backing, and adhered with a polymer. This combination creates a strong yet flexible structure, ideal for various applications, including swimming pools.

One of the major advantages of fiberglass is its adaptability to irregular shapes. This makes it a popular choice for custom pool designs that can’t be easily achieved with other materials. Furthermore, fiberglass is more resistant to wear and tear than traditional pool coatings, making it an excellent choice for long-term durability.

Why Can't Fiberglass Pools Be Fully Above Ground?

The idea of an entirely above ground fiberglass pool might seem appealing, especially with the material's durability. However, fiberglass has its limitations when it comes to supporting the weight and movement of water in an above ground setup.

Fiberglass pools, while strong, are susceptible to flexing when exposed to the pressure of water and the physical activity of swimmers. Over time, this flexing can lead to cracks in the fiberglass structure. Unlike other pool materials, such as liners, fiberglass cannot be easily patched. Once it cracks, the integrity of the entire pool is compromised, leading to costly repairs or even replacement.

Moreover, the constant movement of water, especially when people jump in or climb out, exerts additional pressure on the pool’s walls. To avoid this, fiberglass pools need to be installed with reinforcement, which typically comes from backfilling the area around the pool. This stabilizes the pool structure and prevents excessive flexing. As a result, fiberglass pools should never be installed entirely above ground.

Partially Above Ground Fiberglass Pools: A Viable Solution

If you’re drawn to the idea of an above ground fiberglass swimming pool but are concerned about the limitations, the good news is that partial installation is an option. At Pool Stop Online, we recommend partially above ground fiberglass pools for homeowners who want the aesthetic appeal and long-term durability of fiberglass without the risk of structural damage.

A partially above ground fiberglass pool is installed similarly to a standard pool but with up to 18 inches exposed above ground. This design allows for the beauty of an above ground pool while providing the necessary reinforcement to prevent flexing. The pool is typically framed into a box and backfilled to maintain its shape and structural integrity.

Before installation, proper groundwork is essential to ensure the pool remains level throughout its lifespan. As with any pool installation, selecting an appropriate location and preparing the ground is critical to the success of your above ground fiberglass swimming pool.

Installation Process: How It Works

The installation of a partially above ground fiberglass pool follows a systematic process that ensures longevity and safety. Here’s a breakdown of how it’s done:

1. Ground Preparation: The site is leveled and prepared to ensure the pool remains stable. This step involves removing debris, leveling the ground, and making sure the pool has a solid foundation.
2. Delivery and Placement: Fiberglass pools are pre-molded at a factory and delivered to your home in a single piece. Using a crane, the pool is carefully lifted and positioned into the prepared site.
3. Cutting for Accessories: Once the pool is in place, cutouts for skimmers, drains, and other accessories are made if they haven’t already been pre-installed.
4. Backfilling: After plumbing is installed, the space around the pool is backfilled with materials like pea gravel to provide stability and prevent movement. The backfill process is done carefully to ensure even pressure on the pool walls, reducing the risk of cracks or damage.
5. Final Touches: Once the backfilling is complete, the final plumbing connections and electrical work are done. The pool is then filled with water and prepared for use.

Other Types of Above Ground Pools

If you’re still exploring your options, there are several other types of above ground pools available. However, each has its own set of pros and cons.

• Inflatable Pools: These pools are a quick and budget-friendly solution. They come in larger sizes and can be equipped with pumps and filters. However, they lack the durability and long-lasting appeal of fiberglass pools.
• Steel or PVC Frame Pools: These pools have gained popularity in recent years. With their sturdy frames and durable liners, they offer a balance between ease of installation and longevity. They can also be disassembled during the off-season.
• Hard-Sided Above Ground Pools: Traditional hard-sided pools have evolved over the years, with newer models featuring corrosion-resistant materials. However, they don’t offer the same flexibility in design as fiberglass pools.

FAQs About Fiberglass Pools

1. What Goes Under a Fiberglass Pool?
   • A bed of pea gravel is commonly used to create a solid foundation for a fiberglass pool. This ensures proper drainage and prevents shifts in the pool’s position over time.
2. What Are the Disadvantages of Fiberglass Pools?
   • While fiberglass pools are durable, they are susceptible to spider cracks, discoloration, blistering, and leaks. Prefabricated fiberglass pools also have limitations in terms of size and customization options.
3. How Long Do Fiberglass Pools Last?
   • With proper care, a fiberglass pool can last for several decades. While the gel coating may need reapplication after a decade or so, high-quality fiberglass pools can maintain their integrity for many years.
4. Can Fiberglass Pools Crack in the Winter?
   • Fiberglass pools are generally resistant to cracking, even in colder climates. However, winterization and the use of a pool cover are essential to protect the pool from potential damage during the colder months.
