Among the options available for lining the walls and floor of your swimming pool, today we will focus on PVC liner.
This material consists of waterproof, flexible films normally used to retain chemical products, liquids and waste. In fact, it is commonly used in landfills, since it reduces waste as compared to using soil.
Because it is a material that is waterproof and malleable, it is capable of adapting to the contours and changes in the ground and immediate surroundings.
Also, there are more options than ever for liners, with designs and prints for the pool, adding a bit of appeal to the standard, plain liner.
However, while the characteristics indicated above are apparent advantages, PVC liner has a number of disadvantages. For example, its resistance to ultraviolet rays is much lower than that of glass mosaic, meaning its lifetime is quite limited, especially when used in swimming pools. That is why this material has normally been used as liner underground, where it is not exposed to sunlight.
This material has another disadvantage: its propensity to wrinkle when the pH of the pool changes abruptly.
Furthermore, for this material to remain properly tense/stretched, extreme care must be taken when filling the pool with water, because the liquid is the only element capable of keeping it firm. Otherwise, it is very likely that unsightly wrinkles will appear on the walls and floor of the pool.
Likewise, this material requires constant monitoring of the waterline, because variations in the waterline may cause marks and color variations in the liner.
