How Does a Pool Liner Attach?

Pool liners are necessary for both above-ground and in-ground pools. Pool liners are critical as they act as a barrier between the wall of the pool and the water inside the pool. Many inground pools have tiled walls which eliminates the need for a liner. If you opt for a vinyl pool liner, its important to remember that you will also have a layer of foam that acts as a buffer between the liner and the pool wall.

If you’re in the process of replacing your liner, doing it yourself can help you save a ton of money, however it’s important to remember that these jobs are always best done by a professional.

What is the purpose of a swimming pool liner?

Pool liners are surfaces attached to the walls and floors of swimming pools. They provide support for the pool by keeping water inside. Their appearance of a pool liner also aids in augmenting the aesthetic appeal of your pool. There are a variety of pool liner types including vinyl, cement, fiberglass, tile, and gunite.

Various Attachment Methods:

Attaching the liner to your pool can be done in a variety of ways including:

  • Hung: This method is most commonly used for in-ground pools.

  • Unibead: This method can be used for above-ground and in-ground pools.

  • Overlap: This method is primarily used with odd-shaped pools.

The type of pool you opted for will determine your attachment method. It’s important to consider whether your pool is above ground, underground, or oddly shaded when choosing your attachment method. For more clarity on the attachment method that’s right for you, we suggest consulting an expert.

Understanding the process:

When a pool liner is installed for the first time, the air between the pool structure and the underside of the liner is usually removed with a vacuum to ensure that the liner is in the proper position. Afterward, water is added, and the liner is held in place by the weight of the water.

Through seepage, over-filling, or flooding, water can flow behind the liner and equalize the pressure, allowing the liner to move. These are called “floating” liners which can easily be avoided by ensuring the installation process has been done correctly.

Groundwater can also occasionally lift whole pools from the ground if the surrounding drainage is inadequate. Following the removal of the water source, the water will slowly drain away, but it is important to ensure that the liner is repositioned in the same place. Depending on how much groundwater is present, the water may take a few weeks to drain away.

How can I secure my pool liner?

  • Utilizing an industrial wet and dry vacuum is the most effective method for positioning and securing your pool liner. To ensure an exact fit, the vacuum will be used to pull the liner down the walls. When securing your liner, it’s important to consider the following:

  • Make sure all the pipes connecting the skimmers, inlets, main drain, and vacuum point are taped securely.

  • Use tape or wet towels to close the gap around the swimming pool hose, then start the vacuum cleaner.

  • As soon as you turn on the vacuum, the liner will be sucked back into the walls and floor.

  • The base of the walls may be tense if the liner has not been sucked fully. When the pool is filled, this will correct itself as long as the tension is even across the pool.

  • You should remove the creases along the linerlock by turning the vacuum off and sliding the liner along the seam.

  • Once the vacuum is turned back on, check to see if the liner fits properly.

  • Fill the deep end base of the pool with 75mm of water once the liner is completely installed.

  • Remove the drain fitting at the deep end of the pool.

Are you prepared to attach your pool liner?

Installing your pool liner can be done on your own if you do your research and have the proper tools and supplies. If you don’t feel confident in your ability to line your pool on your own, it’s best to consult a professional that can help you get the job done properly. Consulting a professional will ensure the job is done correctly so you don’t have to worry about your liner lifting or tearing.
