Fiberglass Swimming Pools: Manufacturing, Installation and More



So, you must be ready to get your own inground swimming pool for your home. Chances are there; you must have been thinking about it for years. 


But do you know how each pool type is made and the maintenance these pools need? 


Here's a beginner guide that helps you get the most information that you may need while learning about fiberglass pools


What is a Fiberglass pool?

Fiberglass is a glass fiber blending plastic. When small glass fibers are layered around, they create a lightweight, durable, and flexible material that is perfect for building inground pool shells. 


Fiberglass pools are made with different materials in different forms. However, you need to know that fibreglass pools are not toxic. 


When designing your dream backyard oasis, it's essential to work with experienced swimming pool contractors who can bring your vision to life while ensuring high-quality construction and safety standards.


How Are Fiberglass Pools Made?

Here's basic information regarding how fiberglass pools are made and the manufacturing steps you need to know - 


It starts with a mold. 

The patterns of a pool are made from scratch with the use of wood. Once the wood frame is created, the pool shape is created, and the mold is built inside the pool. 


The mold can be used further for the manufacturing process of fiberglass inground pools that too for hundreds of them, each with the same shape and features. 


Fiberglass Swimming Pool Shell

It starts with spraying the outside of the mold with the gel coat layer, which is the smoother pool surface that you usually see and touch. 


Application of barrier coat 

Next, a vinyl ester resin barrier coat is applied. The vinyl ester resin creates a watertight barrier, which further prevents the gel coat from foaming bubbles. 


These bubbles are known as osmotic blisters. You need to know that it is a common problem that arises with fiberglass pools. 


Use of chopped fiberglass and polyester resin

The next layer includes the usage of polyester resin and chopped fiberglass. You only need one layer of vinyl ester resin for a watertight pool. 


So, the rest of the pool shell is created with the use of traditional polyester resin. 


After that, woven roving, also known as woven glass fibers, is done. It is layered on the stress points of the pool. 


To add more strength, an application of structural honeycomb fiberglass is done in the strategic areas. 


Polyester Resin

In the end, a final layer of fiberglass with polyester resin is removed from the mold before the pool cures. Its excess fiberglass is trimmed from the edges, which further receives a high-quality inspection. 


Installation of Fiberglass Pools



The installation is among the best things about choosing a fiberglass for your home. The reason is that these are extremely fast to install. 


You can expect the installation to be done within 2-4 weeks compared to concrete and vinyl liner pools. Concrete pools take about six months, but vinyl liner pools take about 4-8 weeks. 


Fiberglass pools are made in a manufacturing plant, so they are complete in themselves. Those include spas, tanning ledges, and benches, which you can receive at home. 


Here's an extensive guide on how fiberglass pools are installed - 


Step 1: Excavation 

The excavation of a hole takes about a few hours a day, depending on the pool size. Even if your pool is small, you will see a lot of dirt coming out of the excavation. Don't underestimate how much digging will be involved - it's not the sort of job that you can do alone with a shovel. You'll need to hire a digger from nationwidediggerhire.co.uk equipment rental services or a similar plant hire site that serves your area. Even for a digger, a pool is a lot to excavate, so make sure the digger is hired for long enough to get the job done.


Step 2: Installation

The installer then begins with the installation of fittings and plumbing around the same. 


Step 3: Clean the crushed stone

Next, a layer of clean crushed stones that are of 2-inches thick is placed in the hole. 

The stone around it keeps the pool from shifting and lets it settle over time. It is a common problem that occurs when you use sand. 


Step 4: Setting and Leveling the Pool

Finally, the pool is placed on the ground while setting it and leveling it carefully. You need to do so, depending on the industry standard for the pool. 


Step 5: Filter System Installation

The installers set up the plumbing and install the filter systems. 


Step 6: Backfilling with stones

After that, the installers start backfilling the area around the pool with stone. 

It is important to fill the pool with water while backfilling from the outside as well to keep the pressure equal from both sides. 


Step 7: Waterline Tile and Pool Inspection 

When it is done, the pool is inspected thoroughly, and the waterline tile is installed as you request. 


Step 8: Coping and Patio

Finally, you need to think about coping and patio in the fiberglass pool installation. 

It takes about 2-5 days for the installation process, depending on the patio size and the materials used for the same.


Step 9: Pool Fence

Don’t forget to install a fence around the fiberglass swimming pool to protect the area and make it safer for everyone. To ensure that your pool fence is correctly placed and secure, you will need pool barrier safety inspections melbourne to come, or one in your location, so that you can feel safe in the knowledge that it is fit for people to be near/go in.


Finally…

The installation depends on the weather conditions and scheduling. 


It is essential to note that the swimming pool installation can be messy, even if you are installing fiberglass swimming pools. 


However, it is extremely easy compared to the others.
