How Inground Pools are Made?

When it comes to swimming pools, most people prefer to be blissfully ignorant and would rather just enjoy frolicking in the water rather than getting involved in the day to day cleaning and maintenance duties. However, we also understand there’s a class of people who are a little more hands-on and like to be involved in the background details. For those who are the curious sort and like to know how things work, we’ve come up with a special article to help answer the question of “How are inground pools made?” We’ll cover the three main types of inground swimming pools and give a brief description of each.


Concrete pools were the first types of home-based swimming pools available on the market. Concrete pools are also known as gunite or shotcrete pools. Gunite and shotcrete are mixtures of concrete and sand that is sprayed over a frame made out of metal rebar that is responsible for the shape of the pool. Although gunite and shotcrete are made of the same material, the main difference between the two is the application process. Gunite is sprayed as a dry powder with water added as it leaves the sprayer whereas shotcrete is sprayed as an already wet mixture. And although gunite and shotcrete are very durable, they’re also porous which means they have to be coated to prevent water from leaking through. A plaster coating protects the gunite and shotcrete from the water, but this plaster also needs to be redone every 10 to 15 years. Concrete pools are the longest lasting of all the pool types and are the easiest when it comes to customizing a swimming pool’s size and shape.


Fibreglass pools can have quite an expensive upfront cost because they are typically sold and delivered as a single unit. The entire pool is manufactured in the factory and delivered virtually ready-to-use. This cuts down on the ability to customize the size and shape of fibreglass pools. However, because the pool is already fully formed, they can be installed very quickly and can be fully operational within a week. Fibreglass pools also have a very smooth surface which makes it very hard for algae to grow. This cuts down on the amount of chemicals needed to keep the water chemistry balanced and reduces the overall maintenance costs. 


Vinyl pools are the most economical inground swimming pools to install. They are composed of a plastic or metal frame with walls made of plastic or aluminum and sometimes steel. The walls and frame are covered with a single piece of vinyl, known as a liner, which ultimately contains the water. A drawback to these types of pools is that the liner can be compromised after years of sun and chlorine exposure and will eventually need to be replaced. Vinyl liners are typically replaced every five to 15 years depending on how much wear and tear they experience.
