Gunite Swimming Pools NJ -The Advantages of Gunite Pools NJ

Gunite Swimming Pools NJ – Custom pool builder shares advantages of gunite swimming pools, expert construction techniques, and the benefits of concrete pools.

 

What is gunite? Gunite is a specialty concrete that is pneumatically installed; in general, the term gets its name from the fact that it is “shot” from a hose like a “gun.” The product was originally used by taxidermists to fill plaster models of animals. Today, gunite is commonly known for its use in the swimming pool industry, where it is used to create custom structures on a much larger scale. From taxidermy to building repairs, gunite has a long history of structural uses and artistic applications. In the swimming pool industry, gunite is both structural AND artistic.

There are, as you know, different types of inground pools from which to choose. You can get a liner pool, a fiberglass pool, or a concrete gunite swimming pool. The different structures offer different challenges and benefits. Fiberglass pools, for example, are extremely easy to install because they come in prefabricated shapes that are put in the ground. Concrete pools do not have the luxury of prefabricated shapes, but they do have the luxury of achieving any type of structure you can imagine. With the highly customizable structure comes the challenge of building that structure.

The best way to provide insight into concrete swimming pools is to explain how gunite fits into the pool construction process. As I said earlier, gunite is a special concrete that is pneumatically applied to create inground pools. For concrete pools, the gunite is applied or “shot” at a minimum compressive strength of 4000 psi at 28 days. In the process of pool construction, gunite comes after the pool is excavated, formed, and plumbed. First, the pool is dug and formed. Then plumbing and rebar are completed. Next the pool is shot with gunite to complete the basic structure.

A couple challenges presented by concrete pool designs revolve around the gunite itself. When applied, the builder must be mindful of the gunite that bounces back off the rebar called (rebound). This rebound cannot be used in the structure and must be cleared away so as not to trap the waste material inside the pool shell. The builder must also be very mindful of the curing rate of the pool; in some cases the pool must be watered in areas in order to create a consistent cure throughout the structure. The gunite applier must keep in mind that the gunite needs to wrap tightly all around the rebar to avoid little pockets, known as shadowing. Lastly, pool designs must also address the protection of the concrete. Plasters and tile finishes provide one solution for protecting the structure from the water it holds.

Concrete pools are very appealing because they feature highly customizable pool designs. They offer a great amount of freedom in terms of style and structure. While the advantages are many, challenges present themselves and hands-on experience is required to build the luxurious structures. The gunite plays largely into the safety and durability of a well-built swimming pool. Inground pools, regardless of their beauty and luxurious features, are only as valuable as the structures themselves. The most luxurious pool designs will be a costly waste of time and money if they run into structural problems down the road. The key to avoiding such problems is to deal with a pool company that has experience building complex gunite pools.
