Types

• There are a few types of liners available for pool surfaces. Aboveground pools generally require a vinyl lining that is a part of the structural integrity of the pool. These are available in overlap or beaded styles. The overlap style requires copings to hold the liner in place.
  
  Inground pools are available in fiberglass, where the fiberglass shell acts as the pool's liner. Gunite inground pools are composed of a concrete form covered with a plaster lining. Inground pools can also be vinyl-lined, though the liners have a higher maintenance than the other types of inground pools.
  
  

Features

• Vinyl pool liners come in a variety of thicknesses. Thicker liners are less likely to tear easily, and they last longer than the thinner liners. Thinner liners have a lower price and may serve the immediate purpose of having a swimming pool. They are generally more suited for short-term pool usage, whereas the thicker liners can last for many swimming seasons.

Prevention/Solution

• Extending the life of a pool liner requires preventive measures to slow down the liner's deterioration. Balance the pool water to keep contaminants under control and to prevent damage to the liner. The parameter of the pool must be checked for any buildup of debris, and the pH, alkalinity, calcium and free chlorine have to be measured for adequate quantities in the water. Use pool chemicals in moderation to maintain your liner. Add chemicals separately, and do not mix them.
  
  

Warning

• Do not completely drain your pool because the liner can shrink, or it may tear at its stress points. Clean the liner regularly with mild cleansers formulated for liner care. Also, keep your pool filter system in working order, to purify the water and prevent chemical buildup in the pool. Lastly, immediately patch any small holes and tears with special pool liner repair kits to avoid further damage to your pool liner.
