When renovating a pool or even installing a liner into a new pool, you need to consider the type of liner for the pool you are using. This question is also more than just “is it above ground or and inground pool” question. Most people are aware that PVC pool liners are available in different thicknesses. The main difference is that 0.5 mm thick liners are normally for above ground pools and the 0.75 mm pool liners are typically used to line inground pools. What many people are unaware of is that there is also a reinforced version of pool liners available.
To answer this question properly, you need to understand how pool liners work. The PVC membrane used to make a pool liner is a flexible PVC fabric. It is made to the shape of a pool, and the weight of the water in the pool will keep the liner in place. This is why it is a bad idea to leave a pool empty, as the pool liner will shift. In most situations, this method works very well for securing a pool liner in place. However under certain conditions, say for example indoor pools (that may well be heated), the pool liner can ‘absorb’ water. When the pool liner begins to absorb water, it starts to expand and after a while the liner will wrinkle. The wrinkles typically appear at the bottom of the pool first, but can appear anywhere.
The affected area of vinyl that has wrinkled will eventually start to weaken, and when seen up close cracks can be seen. These tiny cracks if left will eventually form larger tears. As the process is irreversible, once this happens, the lifespan of the liner is greatly reduced.
Using a reinforced Liner
For pool installations where the risk of the pool liner wrinkling is know it is best to use a reinforced PVC pool liner. The Acqua di Lusso range of reinforced pool liners feature an internal reinforcement layer that helps keep the liner stable. These reinforced pool liners are a 3 ply layer design comprising of a PVC base layer, a layer of reinforced polyester mesh that is capped with another layer of PVC. All three layers are permanently fused together to form a homogenously pool liner membrane that can stabilise the pool liner against expansion and shrinkage.
Installation of a Reinforced Pool Liner
The Acqua di Lusso range of inground and above ground pool liners are like other traditional pool liners in that they are fully pre-welded and shaped inside a factory. The liner is then stretched into place onsite.
Reinforced pool liners have to be fabricated onsite, inside the pool, as the reinforced layer does not allow the liner to be stretched and formed to the pool shape. Sections of Acqua di Lusso are laid into the pool, with overlapping seams welded together to form a water tight joint. Edges are also sealed to prevent wicking and finish off the water proofing process. This process also means any shape of pool, including steps and benches can be accommodated.
So if you are looking to install a PVC liner in an indoor pool or other situations where wrinkling may occur, we recommend the use of a reinforced PVC such as Acqua Di Lusso Reinforced.
