Pool liners come in all different kinds of shapes and materials, but one of the most common types is one made from vinyl. These liners are typically constructed of high impact vinyl and plastic composites. Vinyl pool liners play a key role in your swimming pool maintenance, and they give your pool a layer of protection.

Vinyl pool liners feature a bead in the outermost layer, which allows them to fit into the track along the bottom of the pool coping. This liner is placed over a sand, concrete or vermiculite layer and rises up to meet the pool walls, which are usually supported to prevent sagging or bowing. These walls are built up on the panels of your swimming pool and can vary in size and shape, which leads to a variety of vinyl swimming pool liners.
