I have an 18X33 pool that is about 10 years old needs a new liner and some TLC. A main drain was installed several years before we bought the house. The liner was very 'wrinkled' around the main drain when we bought the house and it was obviously floating a little. I found a couple holes and patched them as best I could. The liner stopped floating. Last summer, my daughters friends came to swim and they 'cleaned up' the pool by removing the 'tape' they found at the bottom of the pool. That was the end of the old liner.
I drained the pool before winter and I removed the old liner this week to prepare for the new one. I will be installing the liner with my dad's help.
The straight sides of the pool are leaning out. The lean is more noticeable when the pool is filled. There is a deck around part of the pool and one side wall leans on the deck when the pool is full. The opposite straight wall has a more pronounced lean. However, the buttresses were buried under several inches of landscape rock and that wall is immobile. I have researched oval pools and I believe some lean is to be expected over time due to the weight of the water and inevitable settling of the landscape stones. I also noted, after the liner was removed, that a couple of the landscape stones underneath the side supports are no longer level...possibly due to ground heave. I was also surprised to see that the sand base was extremely thin in some areas and dirt was visible. The straps were not buried in the sand. In addition, the sand was rock hard in several locations and broke apart in sheets.
Anyway, should I attempt to re-level the sides of the pool by replacing the landscape stones under the buttresses...or should I just let it be? I'm going to need to purchase some sand. I have heard masonry sand is often used as a pool base. Is this correct? Also, can anyone give me a sense of how much sand to order if I want to add 1.5 inches of sand to the bottom of the pool.
Thanks in advance.
