What is odd is that the wall came out of the track and moved to the inside. Also, the it came out of the track under the deck. fwiw the deck didn't move the pool.
Over the winter the uprights heaved, and as a result, the wall came out of the bottom track. It is over a 10' span. The uprights have also come loose. The rest of the pool is fine.
How bad is this, and will it collapse?
