While sitting poolside, you’re likely not considering what the pool is made of but rather just soaking in the rays and enjoying a cool beverage. However, if you’re in the market for a pool or need an upgrade to your existing structure, then this article might pique your interest. Read on to learn more about gunite, the strongest, most durable material used for inground pools.

What is Gunite?

Inground pools can be made from three different materials: vinyl liners, fiberglass, or concrete (aka gunite or sprayed concrete.) Gunite is the process of applying dry cement, blowing through a hose, and mixing it with water as it’s sprayed. Reinforced with steel mesh, the material is sticky and holds place once applied. It can be sprayed onto any type or shape of surface, including vertical or overhead areas.

It’s amazing how the original, gooey, and messy application process transforms into a beautiful, functional swimming pool. Although concrete isn’t easy to work with, it’s a proven winner for durability. Ancient Roman architecture is a prime example of the superiority of this dense industrial material that quickly dries while retaining its shape. Concrete-like mixtures have been used as a building material since roughly 6,500 BC.

What is Gunite Made From?

Concrete is generally made from a combination of cement, sand, and some type of aggregate, such as small pieces of hard material like crushed stone or gravel, all mixed with water. Sometimes, it’s made of lime or silicate powder.

China is the largest producer of cement. Cement is the most widely used manufactured material globally and is second only to water as the most widely used substance worldwide. Gunite for pools has highly compressed strength, which makes it impermeable to water and frost resistance.

History of the Gunite Pool

Concrete pools, which date back to the era of Roman baths, were transformed in the 1940s with the introduction of gunite construction. With newly returning WWII veterans, families sought comfortable places of refuge in their suburban homes. Gunite is a technique that revolutionized pool construction, enabling builders to craft appealing, customized pools with greater ease.

Craftsmen and builders no longer depend on heavy, removable molds or forms to create shaped concrete. The invention of gunite prevents the need for extensive heavy machinery and intensive labor to create casts or templates that shape poured concrete until it sets. Gunite simplifies the creation of unique swimming pools.
