How Does Pool Plaster Get Damaged?
Few people give it much thought, but there’s a great, unsung “hero” in the safe, reliable operation of a swimming pool and that is the pool plaster. When it gets damaged, this can create some big, expensive problems for you until the situation is sorted out. So what exactly is pool plaster, and how can it get damaged? We’ll look at that now.
Separating Your Home From Your Pool
While the basic premise of a swimming pool is “a big hole with water in it,” you can’t just leave it at that, otherwise all swimming pools would be created with a shovel and some enthusiasm. Pool plaster is a waterproof substance that is applied to the swimming pool once the hole has been dug and the materials have been laid out. It is a layer of water proof substances that is designed to make sure that the water stays in the pool.
Without pool plaster in your swimming pool, the rate at which you need more water to replenish your pool would make it financially impractical for most people to keep one. Water leaking through a pool would contaminate the surrounding ground with the pool water chemicals, and the water itself could damage the concrete, tile, or other aspects of the yard you have around the pool.
While pool plaster is designed to protect your pool for years, that doesn’t mean it’s impervious to harm. Neglect pool plaster for long enough, or subject it to certain conditions, and, like most materials, it will reach a breaking point. At that juncture, you’ll need a swimming pool repair service to restore your plaster and enjoy a fully functioning pool once more. There are a few ways that plaster can become damaged.
Water is a natural medium for chemical reactions, so when things enter the water, this can alter the chemistry within the pool. That altered chemistry can sometimes damage pool plaster. The addition of rain water can alter water chemistry in a pool. Too much evaporation and then replacing the evaporated water without considering the chemistry will inevitably change chemical levels. Even falling leaves, or cut grass blown by wind into the pool or bird droppings can alter this chemistry.
Remember, your pool may essentially be a big hole, but once you line it with stone and tile, put plaster on it, and then fill it with countless gallons of water, it’s a very heavy object, and, like your home, it’s still sitting on top of soil. Soil is soft and malleable and prone to movement over the years, which can create empty spaces that used to be solid ground. In the same way that this can cause a home’s foundation to shift and eventually crack, the same can happen to swimming pools. At best, if this happens, very minor, hairline cracks in plaster can occur, which don’t mean leaks, but can provide a safe haven for algae, which then alters the water chemistry. At worst, the cracks can mean leaks, which get both serious and expensive. This is why you should always have your pool’s plaster taken care of by a swimming pool repair service.
