Vinyl Pool Liners
A vinyl liner pool has a custom made sheet of vinyl between the water and the pool structure. This is in contrast to a gunite or shotcrete pool which uses plaster as its waterproofing membrane. Vinyl liners typically lock their top edge, called a bead, into a track located on the bottom of the coping, which is at deck level. Underneath the liner is a sand or cementitious floor, specified in dimension to the "cut" of the liner that is to be used. The floors come up to meet the walls, which are commonly 3 ft by 8 ft panels made of galvanized steel or thermoplastic. These walls are supported from behind so that they won't bow out against the weight of the water. All of the wall panels are secured together to make up the perimeter shape of the pool. For this reason, there are some limitations to the possible shapes of a vinyl liner pool.
Why Is My Vinyl Pool Liners Losing Color?
The original color of your liner will fade with the use of sanitizing chemicals and the effects of the sun. High concentrations of harsh chemicals should be avoided. This will remove the plasticizers which give liners their resiliency, leading to brittle vinyl, which leads to new liners. The chemical makeup of modern vinyl allows manufacturers to create liners that are now much more durable and resistant to chemical, solar and algae problems, however, your liner’s color will inevitably fade over the years.
Is Your Vinyl Pool Liners Leaking?
Not an uncommon problem. Liners are typically manufactured in 20 mil thickness (28-30 mil option). Although resistant to punctures, it can and will happen. Especially as the liner ages, losing its resiliency. If you are fortunate enough to see a small hole in the liner, simply patch it with a vinyl liner patch kit. If the hole is underwater, buy a "wet" patch kit. This service can also be performed by our professional technicians–simply contact us today. If you are adding more than one inch of water to your pool per week, discounting splashed-out and backwash waste water, you probably have a leak. Do not allow leaks to go unchecked. Leaks can wash out supporting backfill behind the walls, corrode the walls, and may wash away sand on the floor, creating large sinkholes. It is not advised to drain your vinyl liner pool, or allow it to leak out below the level of the walls. The water in the pool holds the liner tightly against the walls and floor. If the water is removed, the liner must be reset with a vacuum to suck the liner into place while filling. Otherwise, large wrinkles may appear when filling a loose fitting liner. In addition, an empty liner pool may allow rainwater to seep in under the walls, washing away and destroying the specifically contoured shape of the floor. There also exists the risk of a wall collapsing or caving in.
A pool liner lasts on average between 10 and 15 years. If you have suspicions that yours might need replacing, give us a call today!
