Types of swimming pools
Now we come to the types of swimming, there are many different types of pools and they are described differently, but i will stay with the 3 main types used here in the UK.
Above-Ground Swimming Pools
This type of pool is often the cheapest kind to install, they are typically made of , plastic panels, steel panels or in some cases even timber. they generaly have a liner fitted after construction, this is sometimes refered to as a “bag liner” ( i will explain this in another topic). These type of pools are often sold in a kit form and with some basic DIY knowledge can be quite easily installed. They are a great cheap way of putting a fully functional pool in your garden and having lots of fun. They as it suggests the least desierable of pools as they have many long term disadvantages to more solid Fibreglass of concrete construction pools. They are much less durable and of course if just stuck in the middle of your garden, they don`t look as good.
In Ground Liner pools
This type of pool here in the UK is often built from concrete blocks. A whole is excavated, foundations put in place, the pool wall constructed. Then the pool walls and floor are rendered to create a smooth finish, a smooth finish is eesential to prevent anything puncturing the liner from behind, once the water is added. Particular attention has to be given to excess ground water with these designs and a hydrostatic pump will often have to be fitted to take away any excess ground water.
Fibre Glass Pools
Fibre glass pools are mostly made in one piece, they are then gel coated and vynil resins used to create a very smooth surface. They can come in many different shapes and sizes and for this reason they are very popular.
They can be installed very quickly, either fully in the ground, partly or totally above ground. This has an advantage if you are in a very high water table area.
Concrete Pools
This type of pool is by far the most expensive and time consuming to construct. Today they are often built from to skins of concrete blocks which have re-inforced steel bars connected to a very thick foundation, the cavity that is formed is then poured with concrete to form a very very strong wall construction. This type of pool is often built if you require a tiled pool, tiled pools have to have a very strong surface, because if there is any movement at all they will crack and fall off and the water retention properties will be severly compromised.. Often this type of pool is only used for indoor pools. Typically for hrdrotherapy pools were non-slip surfaces are very important, also tiled pools can withstand very high temperatures. Vinyl lined pools do not like the water temperature to high or they will start to destabilize and their active life will be shortened quite considerably.
This type of pool has many advantages over above-ground pools for many reasons
