The Three Main Types Of Inground Swimming Pools

by Pool Builders on 03-14-2013 in Articles

There are three main types of inground swimming pools. Each has their advantages and disadvantages. This article is a brief description of each inground pool type.

Concrete pools are custom built on site offering you many different styles and options. A steel reinforced structure is first built. While these steel frames are being installed, plumbing pipe will also be installed. The plumbing pipes that are being installed are longer then you need, but after being checked for leaks, they will be cut off flush with the edge of the pool.

Gunite, sometimes called shotcrete is sprayed over this steel frame. This spraying process must be done by an expert experienced with the nozzle operation. The skill in doing this spraying is critical to producing a strong pool. The thickness of the gunite will depend on pool design, budget, and ground conditions. The next step will be to install the plaster over the gunite.

Once the gunite is dry, it is carefully smoothed to prepare the surface for the plastering stage. The plastering is available in different colors, along with many different colors and styles of tile that can be used for the border around the pool. The construction is complex and should be done by very experienced pool installers. This type of pool construction, generally takes longer to install then a Liner Pool or a Fiberglass Pool.

Fiberglass pools are manufactured from fiberglass-reinforced plastic that has been formed into a certain shape and size inside a preformed mold at the factory. This molded plastic is then covered with a product named gel coat. This coating creates a smooth finish that is available in different colors. This pool does not use external braces, but it must be installed in a specifically dug hole and must be supported with the proper backfill according to the manufacturer's instructions.

The pool leaves the factory on a flatbed truck and at the job site a crane is used to remove the pool for placement in the excavated hole. Since most manufacturers offer certain size and shape molds, unlimited sizes and shapes are not available. Installation of this pool is fairly quick. Price wise, Fiberglass pools are usually much more expensive than vinyl liner pools, but less than concrete.

The homeowner needs to be very satisfied with their pool selection before the signing of the contract. This pool is not manufactured on site and has to be manufactured in a special mold, and then delivered to you. There is no changing your mind once the job has started. Do your homework first and choose the shape and size that will fit your family's needs.

The last main type of inground swimming pool is a vinyl liner pool. Let's first discuss what a vinyl liner is. It is a material that is manufactured from virgin material (never used, not reprocessed) and is treated with a fungicide to inhibit bacteria growth. This material is available in many different colors and pattern designs. It is also available in different thickness, example; 20 mil vs. 28 mil (this is thicker material).

This liner can be made in any shape or size. The liner is installed against panels of a pool which could be manufactured from Aluminum, Galvanized Steel, Polymer, Stainless Steel and still in some cases Wood. The liner offers a very smooth surface which is very pleasing to your feet.

A vinyl liner pool can be manufactured to look a lot like a concrete pool but is a lot less expensive. If you get tired of looking at the same liner you have in your pool for the last 15 years, you can easily change to a new pattern. With today's technology, this type of pool can be designed to fit virtually any size or shape you want.

These pools can be designed to offer you different depth options. The shallow end could be 42" or 48". The three most popular deep end depths are 5', 6' or 8' (at least 8' is needed for diving) but other depths are available. With today's standards, if you want a pool to have an 8' deep end, the pool size must be at least 16' wide and 32' long.

Which one is best for you? Compare options, features, and your budget when you make your decision.
