As someone that has built pools, I disagree.
A concrete or Gunite pool (gunite is basically cement with sand as the aggregate vs gravel),is held together with rebar. It can and will float like a boat regardless of what happens around it.
This home owner spent a lot of money to build a pool in what is basically rock. Soft rock, no doubt. Concrete/cement is stronger than limestone.
There are three things that can cause major problems for a pool builder. Rock, fill and water. Both rock and fill can be dealt with, but not without additional expense. Water is the worst. I’ve built pools under all three conditions and the “Pool from hell” was built in/on an underground stream.
In the video and photos, I think that if the pool was built properly, it would not crack and would fall into the lake whole.
Thanks. Do pools in Texas need to be drained periodically? And how do they do that? I’m guessing they don’t just dump it over the edge?
Then again, that whole area is going to end up in the lake at some point. Just like where I live - although I’m probably good for another 1 million years.
