It’s not just about aesthetics; Failure to renovate a liner can damage the pool and cause leaks.

The renovation of the liner

The liner is placed on the pool support. This waterproof bag is made of welded PVC layers that adapt to all pool shapes.

If your liner is simply punctured, you can simply repair the hole with the appropriate equipment, without having to empty the pool.
