Fiberglass is used for in-ground swimming pools and provides for outstanding and durable support when properly installed. It's known to be stronger than concrete and can withstand shifts in the earth without putting stress on the structure like a gunite or concrete pool may encounter. Fiberglass however, must be pre-formed to meet the buyer's needs and cannot be altered once made. It's installed into an already excavated hole in the ground dug prior to delivery.
Fiberglass is molded from a single sheet material that's bonded to the shape and design you request. The installation of a fiberglass pool is relatively straightforward once the hole has been dug. Most of the preparation is done before the pool arrives. Upon arrival, the installers will level the pool and back-fill the surrounding areas to finish the job. The different types of fiberglass pool lie in the shape of the design. Buyers pick a design that is best suited to their needs and preferences.
The only difference in fiberglass pools lie between manufacturers. Several companies manufacture fiberglass pools and they all claim to be the best, but in reality they are all made from the same materials. The only difference between manufacturers might be the difference between fiberglass coatings used to protect the pool walls. But even that's less likely as most manufacturers use a universal coating meant to protect the pool from corrosion and water damage.
Fiberglass pools offer an alternative method to install an in-ground pool. The pool comes already manufactured when it arrives to your home and is installed in any shape you need. Algae growth is less likely on a fiberglass pool surface because the bacteria cannot bond to the fiberglass structure. Prices of fiberglass pools, like all other pool types, are mostly determined by the size of the pool itself. They are also less likely to crack than concrete pools and do not require a liner change as vinyl pools need occasionally.
