What is Behind a Vinyl Pool Liner?

Vinyl-lined pools attract owners’ attention because of what they can see most clearly – the huge water barrier that covers a mass surface. Vinyl liners have a sheet of vinyl that sits between the water and the floor and walls of the pool, and an underlayment of sand and other materials are trowelled into place beneath the liner to make sure everything stays secure. It’s important that these elements of a vinyl pool liner are constructed by an experienced professional. If not done correctly, the pool liner can develop wrinkles and soft spots. This normally occurs if water seeps in behind the liner and consequently, the liner will lift and float.
