Fibreglass Pools: How Are They Made?

Fibreglass pools have been gaining popularity among homeowners for their easy installation, minimal maintenance, and aesthetically pleasing designs. But have you ever wondered how these seamless structures are created? Let’s dive in to explore the fascinating process behind the making of fibreglass pools.

Step 1: Design and Mould Creation

The initial phase of constructing a fibreglass pool starts with the meticulous process of designing a mould. This crucial stage plays a vital role in determining the exact shape, size, and contour of the ultimate product. To achieve impeccable fit and finish, the mould is crafted with precision using a composite material specially chosen for its durability and reliability. By paying meticulous attention to detail during this stage, the foundation is set for creating a fibreglass pool that meets the highest standards of quality and craftsmanship.

Step 2: Applying the Gel Coat

Once the mould is prepared and in place, the first layer applied is a gel coat. This gel coat, a pigmented layer of polyester resin, serves a dual purpose. Not only does it provide the pool with its desired colour and a sleek, smooth finish, but it also plays a crucial role in ensuring the pool’s water remains resistant to stains. By adding this protective layer, the pool becomes more durable and easier to maintain, allowing for long-lasting enjoyment and peace of mind.

Step 3: Layering the Fibreglass

Next, multiple layers of fibreglass matting are meticulously applied on top of the gel coat. To ensure a strong bond, the fibreglass is expertly combined with a high-quality resin using a technique known as ‘chopping.’ This method involves spraying the resin and fibreglass mixture onto the mould, allowing for optimal distribution and a consistent application. The result is a durable and flexible structure that can withstand the test of time and environmental stresses.

Step 4: Adding Strength with Honeycomb Divinycell

To enhance strength without adding extra weight, manufacturers frequently utilise Divinycell, a durable and honeycomb-shaped plastic material. This innovative material is strategically layered between fibreglass sheets, providing additional rigidity to the pool structure. By doing so, it effectively prevents any potential bulges or shifts in the ground from distorting the pool’s shape, ensuring its long-lasting integrity and durability.

Step 5: Final Layers and Curing

Finally, after the required layers of fibreglass and resin are applied, the pool undergoes a meticulous process to achieve the desired thickness. The additional layers are carefully added, allowing each one to blend seamlessly with the previous layer, creating a sturdy and robust structure. Once the application is complete, the pool is left to undergo the curing process. Curing is a chemical reaction that transforms the liquid resin into a solid state, resulting in a firm and durable structure that can withstand the test of time. This meticulous process ensures that the pool is not only aesthetically pleasing but also built to last.

Step 6: Quality Control

After the post-curing process, the pool goes through a series of meticulous quality control checks to guarantee a flawless finish before it is considered ready for installation. Every nook and cranny is inspected for any imperfections, which are promptly rectified to ensure the highest level of craftsmanship. As a final touch, the pool may undergo a gentle buffing to further enhance its already captivating aesthetic appeal, leaving you with a stunning addition to your space.

Choosing a Professional

As you can see from above, constructing a fibreglass pool is not an easy feat. A professional and reputable pool builder should be chosen with care as their expertise and attention to detail will impact the final product’s quality and durability. By opting for an experienced pool builder, you can rest assured that your dream of owning a stunning fibreglass pool will become a reality – one that adds practicality, aesthetic appeal, and value to your property.

What to Consider

Selecting the right pool builder to construct your fibreglass or lap pools perth is a crucial step. When making this important decision, there are several key factors you should consider.

Experience and Reputation

When looking for a pool builder, it’s important to find someone with a proven track record and extensive experience. Choose professionals who have successfully completed multiple pool projects and have positive reviews from previous clients. This ensures a reliable and trustworthy choice, giving you peace of mind during the construction process.

Licensing and Insurance

Ensure that your prospective pool builder has the necessary licensing and insurance. This not only guarantees that they are qualified for the job, but also provides protection in the event of any unforeseen circumstances during the project.

Get Quotes

Obtaining multiple quotes from fibreglass pool builders is crucial for making an informed decision. Compare prices, services, and completion time. Detailed quotes are key, outlining all costs including materials and labour. Be cautious of seemingly too-good-to-be-true quotes, as hidden costs may arise. Remember, the cheapest option isn’t always the best. Consider quality workmanship, customer service, and a proven track record.

Portfolio of Past Projects

A pool builder’s past projects can provide an insight into their work quality and style. Request to see their portfolio, or visit their website to view images and details of completed pools. This can help you decide if they are capable of delivering the design and aesthetics you are aiming for.


A reputable pool builder should offer a reasonable warranty and comprehensive coverage, demonstrating confidence in their workmanship. This level of assurance ensures that any issues will be promptly addressed, protecting your pool investment for years to come.

Clear Communication

Good communication is essential throughout the pool construction process. Your chosen pool builder should be able to communicate clearly and effectively, keeping you informed at each stage of the process and addressing any queries or concerns.


Building a fibreglass pool is a complex process that requires precise execution and attention to detail. From mould preparation to gel coat application, fibreglass layering, and quality control, each step is crucial for creating a durable and visually appealing pool. Choosing a professional pool builder with experience, reputation, licensing, and insurance is equally important for a successful outcome. By considering these factors, you can ensure your fibreglass pool is a valuable and long-lasting addition to your property.
