Indoor swimming pools provide a convenient and controlled environment for year-round swimming, especially in residential developments, private clubs, and hospitality facilities. A critical component of these pools is the PVC liner, which serves as a waterproof membrane that prevents leaks and maintains water quality. Over time, however, PVC liners may suffer from wear and tear, chemical degradation, or mechanical damage—resulting in leaks, wrinkles, and visible surface damage. Prompt repair of a damaged liner is essential to avoid water loss, structural issues, and increased operational costs.
