If you're planning on building a pool, there's a lot to think about, especially when it comes to picking the materials. In this piece, we're comparing Insulated Concrete Forms (ICFs) and fiberglass pools head to head to see which one comes out on top. We'll go through the good and the bad of each option so you'll have all the info you need to make the best decision.

Introducing ICF vs. Fiberglass Pools

In the world of pool construction, ICF and fiberglass pools are two prominent options. ICF pools, made with insulating concrete forms, are renowned for their durability and energy efficiency. On the other hand, fiberglass pools are popular for their smooth finish and relatively quick installation.

The Common Ways to Build a Pool: Concrete and Fiberglass

The most common way to construct a pool involves either concrete or fiberglass.

Concrete Construction Methods

There are two main types of concrete pools: cast-in-place concrete pools and shotcrete (or gunite) pools. These types of pools can be customized in order to provide design flexibility to fit your particular site needs.

Cast-in-place Concrete Pools

Concrete pools are constructed by creating a wooden form in the shape of the desired pool, then pouring concrete directly into the form. Once the concrete has cured, the form is removed, and what’s left is a sturdy concrete shell. This method allows for a high level of customization and can accommodate virtually any pool shape or design.

Shotcrete (or Gunite) Pools

Shotcrete is a method of applying concrete at high velocity onto a reinforced steel framework. Gunite, a specific type of shotcrete, uses a dry mix of cement and sand, to which water is added at the nozzle during application. These pools are known for their durability and flexibility in design. Once the shotcrete or gunite has been applied and allowed to cure, a final layer of plaster, tile, or paint is often added to the interior of the pool to create a smooth and appealing finish.

Both types of traditional concrete pools offer advantages in terms of design flexibility and durability. However, they can be more labor-intensive and time-consuming to build compared to other pool types, like fiberglass or ICF pools.

Fiberglass Construction Methods

Fiberglass pools, however, come as pre-formed shells, which limits customization but simplifies installation. The process of manufacturing fiberglass pools involves several key steps that culminate in a smooth, pre-formed pool shell.

1. Plug / Pattern Creation

The process begins with building a plug, also known as the pattern. This is an exact, full-sized model of the pool, often made from materials like wood or steel, then layered with fiberglass and body filler. It is finished with primer to create a smooth, precise surface[1].

2. Mold Creation

Next, a mold is created from the plug. This involves applying a gel coat to the plug, followed by several layers of fiberglass and resin. Once cured, this forms a durable mold that's an exact negative of the plug.

3. Pool Shell Production

Using the mold, the fiberglass pool shell is produced. This involves applying a gel coat to the interior of the mold, followed by several layers of fiberglass and resin. The shell is then left to cure.

4. Finishing Touches

After the shell has fully cured, it's carefully removed from the mold. Any final touches, such as drilling holes for fittings and applying a final layer of protective coating, are carried out.

This manufacturing process results in a lightweight, durable pool shell that can be installed quickly to provide homeowners with a ready-made swimming pool that requires minimal construction work on site.

Pros and Cons of Each Material

Concrete and fiberglass pools each have their merits:

Fiberglass Pools

Certainly, while ICF pools bring their unique set of advantages, fiberglass pools also have a number of benefits that can make them an appealing option for many homeowners.

  • Efficient Installation: Fiberglass pools come as pre-formed shells that can be installed quickly, which is a faster route to enjoying your new pool.

  • Smooth Finish: The smooth interior surface of a fiberglass pool is comfortable and friendly to swimmers' feet, while also being resistant to algae growth.

  • Non-Abrasive Surface: The non-porous surface of fiberglass pools is gentle on swimwear and doesn't cause skin abrasions, for a comfortable swimming experience.

Despite these advantages, it's essential to consider the long-term sustainability, durability, and energy efficiency of your pool, in areas where ICF pool construction has demonstrated superior performance.

Insulated Concrete Form (ICF) pools have their own distinctive set of advantages that make them an attractive choice for homeowners seeking longevity, efficiency, and flexibility.

  • Enhanced Durability: ICF pools are known for their strength and long lifespan, and they provide a sturdy structure that can withstand varying weather conditions over the years.

  • Increased Energy Efficiency: With their excellent insulation properties, ICF pools help maintain a consistent water temperature, which reduces the need for frequent heating, which can lead to significant energy savings.

  • Customizable Design: Unlike pre-formed fiberglass pools, ICF pools can be customized to fit any design or size specifications, for creative freedom in shaping your pool.

  • Comfort: The insulated forms used in ICF pools can provide a more comfortable swimming experience, as they help to maintain a consistent water temperature.
  • Lower Long-term Maintenance: While ICF pools may require more initial work, they demand less maintenance in the long run compared to traditional concrete and fiberglass pools.

These benefits underline the value of considering ICF pool construction, particularly for homeowners focused on long-term sustainability and energy efficiency.

Why ICFs with Concrete Are Better Than Traditional Methods

ICF construction takes concrete pools a step further and enhances the benefits of traditional concrete pools. ICF pools use insulated forms as a mold for the concrete which results in a structure with superior insulation and durability. This not only increases the lifespan of the pool but also makes it more energy-efficient, to save homeowners money on heating costs.

Choosing ICFs for pool construction can provide several notable advantages over standard concrete or shotcrete pools.

  • Superior Insulation: ICF pools offer unparalleled insulation, and can reduce energy costs by maintaining a consistent water temperature. This feature is a significant improvement over standard concrete pools, which lack this level of insulation.

  • Enhanced Structural Integrity: The combination of concrete and foam in ICFs creates a highly durable structure, and provides more resistance to cracks and leaks compared to standard concrete or shotcrete pools.

  • Reduced Construction Time: Although standard concrete pools can be built fairly quickly, ICF construction further accelerates the process due to the use of prefabricated forms.

  • Lower Long-term Maintenance: Unlike standard concrete pools, which may require regular resurfacing, ICF pools maintain their structure and appearance over time, which can lead to fewer long-term maintenance requirements.

  • Noise Reduction: An added advantage of ICF pools is the sound insulation provided by the foam, which contributes to a quieter, more relaxing pool environment.

These features underscore the advantages of choosing ICFs over standard concrete or shotcrete when considering pool construction. It's an investment in a long-lasting, energy-efficient, and cost-effective backyard oasis.
