If you are considering installing a pool in your backyard, you have a few choices. Among those choices are a cement/concrete pool, or a fiberglass drop-in pool. Most pool installation experts would recommend a cement/concrete pool, as a fiberglass one will need more repairs over its lifetime. Here is why a fiberglass pool will need more pool repair services later on.
Fiberglass Eventually Wears Out
If you live in the same home for at least twenty years, you will find that your fiberglass tub will need to be replaced at least once. Cracks develop in the sides and/or bottom of the tub from the weight of water and the weight of people standing on the bottom. The cracks become more pronounced the longer you leave them be, and then you begin to deal with water damage underneath the tub.
The same holds true for fiberglass pools. The areas where people can stand and touch the bottom are usually the areas that get a crack first. The sides of these pools will crack if something really heavy slams into them. Thankfully, the only water damage you have to worry about here is a flooded underground.
Drop-in Pools Are One Uniform Unit
Drop-in pools are one complete unit. If they do get cracks, it is difficult to repair them without creating bigger problems with the unit as a whole. The cracks have to be sanded smooth, filled, and sanded again. Then the filled cracks have to be sealed to make the filler waterproof. If the job is rushed, the vibrations from a faster sanding job reverberate through the entire pool, which could then cause more cracks to appear if the structural integrity of the drop-in unit is sketchy.
You could also have a drop-in pool that is two pieces, which is even worse. The seams of these two pieces have to be constantly checked every season before you fill the pool to make sure they are still watertight. Thankfully, your pool service contractor can do that after the pool is emptied for winter and just before it is cleaned.
Shifting Ground Breaks the Pool
You will find that most pools in California are cement or concrete. That is because shifting ground, or ground that quakes, causes the supporting ground underneath a fiberglass drop-in pool to drop off. Then the pool is not adequately supported, and it begins to shift downward on some areas. Sooner or later the lack of support in these areas underneath causes the fiberglass pool to crack. When that happens, nothing short of an excavation and removal of the drop-in to level the ground is going to fix the problem.
