Above ground pool in ground?

Answer:
This is very possible, and has been done by many above ground pool owners. It provides the same look and benefits of an in-ground but at a fraction of a price, you can even create a deep end in an above ground pool by adding an expandable liner that can give u an additional two feet of depth. I purchased a pool from www.1abovegroundpoolsdirect.com, and they were able to assist me with this worthwhile idea. Best of luck!

Sounds like a sales pitch to me. I have personally seen a dozen or more of these failed pool installations. The reason they ALL fail is really quite simple.
Hydrostatic pressure. The walls of an above ground pool are not made to withstand even the smallest amount of pressure that is caused by groundwater. Even someone who has no knowledge of our industry can, with a little thought, understand why the concept is doomed to failure. If your pool is located in the desert, there is no reason to continue reading.
Let me help the "thought process" and possibly save someone thousands of dollars by just using common sense. There are 4 types of in-ground swimming pools: Concrete, gunite, vinyl liner, and fiberglass. They all share one thing in common: the walls.
They are built or manufactured in such a way as to withstand hydrostatic pressure. The wall of each pool is the first 3 1/2' down from the top of the pool. In other words, no matter how deep the pool may be, the first 3 1/2' is the wall and everything else is called the bottom.
Concrete and gunite pools have a one foot thick wall; the rest of the pool is only 8". Vinyl liner pool walls, usually made of galvanized steel or fiberglass are only about 1/2" thick, but they are anchored to the ground with "A" braces every 8 feet. A concrete pier is then poured on the end of each "A" brace, and a concrete collar is poured at the bottom of the wall all around the entire pool. Fiberglass pool walls are 5/8" thick and made with many layers of fiberglass, vinyl ester resin, and gel coat creating an extremely strong laminate.
All this with just one purpose in mind: to withstand the hydrostatic pressure that will begin attacking these walls the very first time it rains or snows. Common sense tells us that this rain and snow must go somewhere, and the obvious answer is "into the ground". Water actually moves underground thus the term: hydrostatic pressure.
With this in mind, check out the walls of an above ground pool. Consider how well they will handle hydrostatic pressure compared to a foot of concrete or any of the other wall listed above. Now you can make an intelligent decision about how not to waste several thousand dollars.

Installed out of ground in ground many times - works great and all have lasted at least 10 yrs. just don't keep it empty for too long or earth may cave.
