Swimming pool liner
Liner is a PVC coating system for pools. It is an inexpensive way to waterproof the pool. It has the advantage of being comfortable to walk on and is long-lasting.
Pool liner has revolutionized the construction of swimming pols. It is the most popular way of coating pools throughout the world. Before it appeared, it was expensive and complicated to waterproof a pool.
Liner a highly resistant PVC coating. It consists of a large pocket which is fitted flush against the walls of the pool, and as it is flexible it can is efficient even for pools with irregular shapes. It is easy and inexpensive to install and is perfectly leakproof. It is kept in place by the weight of the pool's water. It is pressed against the walls of the pool, thus taking its form, and it is soft and smooth. The pool must always be filled with water, as it is the water pressure which holds the liner in position.
There is a very wide range of pool liner. The least expensive are the thinnest ones, having a thickness of 0.45mm. minimum. The most expensive can be up to 0.85mm. thick. The thicker the liner, the longer it lasts.
Generally speaking, a good liner will last around 10 years. If your pool is used intensively by children, you can opt for a liner which is reinforced by the presence of a sheet of polyester which is inserted between two sheets of PVC.
Many colours are available, depending on the manufacturer. Sky blue is the classic colour, but liner with decorative prints are becoming more and more popular, giving a touch of originality to the pool. Friezes can also be added to plain or printed liners to personalize them even more.
All liners on the market are treated with polyvinyl chloride, a perfectly resistant material, which protects them from the effects of ultra-violet light, allowing them to keep their colour longer. Other treatments, like that against the development of fungi, can be added. You can also treat against bacteria, staining, abrasion (by applying a varnis), and so on...
