How Is A Fiberglass Pool Installed?

A fiberglass pool is molded in the factory and installed into an excavated hole by experts.  If you want a pool within the shortest time possible, then this is an ideal option. Furthermore, fiberglass has a superfine gel coat finish that is not only durable but also stain resistant. Another advantage associated with fiberglass pools is that they are non porous, which means they harbor lesser algae compared to their concrete counterparts.  One common question that lingers on most people's mind is how a fiberglass pool is installed. Below is a brief overview of the process.


When pool contractors arrive in your house, they will draw the design of your fiberglass pool on the ground using paint. They will use the dig sheet provided by the manufacturer to determine the excavation depth of certain points of the hole. These paint inscriptions are known as hash marks and will act as the guideline to ensure the desired depth stipulated by the manufacturer is achieved during excavation. The team will use an excavator to dig the hole and the skid steer to move the gravel and dirt from the site.

Laying the Foundation

After excavation, the next step is laying the foundation upon which the pool will rest. A gravel base is preferred as opposed to a sand one due to certain reasons, such as preventing pool settlement and leakage.  Problems with sands are attributed to the fact that it is not possible to completely compact it and thus it puts pressure on the sidewalls of the pool after some time, resulting in leakages. A layer of gravel with a thickness of 2 inches provides a stable foundation to rest the pool. One of the most critical aspects of this phase is to ensure the gravel foundation is at a perfect level. Contractors set the gravel using a laser level to achieve the exact elevation.

Setting up the Filter system and plumbing

The filter system is primarily made up of filter and a pool pump. Circulation of water in the pool is carried out by the pump, while the filter helps in removing particles and debris from the water. Other elements found in the filter system include the pool light switch, valves for controlling water flow and chlorinators for salty water. The filter system is set up away from the pool by an electrician, preferably in the house. Fiberglass pools will come with their own plumbing system consisting of rigid PVC pipes and plumbing straps. The crew will install the plumbing system on the pool shell before setting it into the excavated hole.They will inspect all the fittings closely to ensure there is no leakage.

Back filling

The pool will be lifted using a crane or an excavator and set out on the gravel foundation. The crew will repeatedly lift and reset the fiberglass pool on the foundation until they achieve the desired level.  After this, the empty areas around the pool are back filled with gravel. It is recommended  to use the 3/4 to 1 inch of crushed blue stone that is free from fines, such as stone dust as the back fill because it drains easily.  The next step is to circulate water into the pool through the already installed filter and filter system.

Pool patio and fencing

Once the team inspects the back filled fiberglass pool and ensure all the systems are working, they will install a patio and coping around the pool top. The patio and the fiberglass are fused together using rods to ensure structural stability. After the patio is complete, the final step is building a fence that completely surrounds the pool as stipulated by the national building code regulations.

If you want to install a fiberglass pool, all you need is to contact reputable pool contractors who will carry out the process promptly. For pool contractors, contact a business such as Elite Pools and Spas.
