So, deciding on the base for the new pool going in and I am leaning towards using crushed limestone, unless someone can give me a good reason as to why not...
I need to fill in about 4+ inches of elevation to where I want the pool to sit and as it turns out I am planning on using limestone for the paver base (since it sets up like concrete after it gets wet and dries out), and I have found references to people using it for a pool base as well, which would totally simplify things for this project. I have also found some offhanded commentary that the limestone will react with the liner and bases/walls if you have a all-steel pool, but the one I have is resin bottom plates and rails with steel wall and top plates and upper reinforcing ring, as well as using foam on the walls, foam flooring and foam cove, so I don't even think that concern applies, does it?
Now, even if I use limestone, should I plan on using 12x12x2 pavers under the uprights? For pavers it is commonly accepted that the limestone, once wet, compacted and dried out is almost like concrete, so if that applies, and since I am using a vibratory compactor along with the proper amount of moisture to compact every 2" of lift, is there any reason to use pavers under the uprights?
Personally, it is only a $30 or so expense for the pavers, so I don't mind doing it, but for the extra work is it buying me anything? If it is "common and accepted" practice to just do it regardless of the aggregate, so be it, it will be done, but I know that the AquaLeader instructions state that for the "best installation base" to use a compacted crushed aggregate for a 2ft ring with the pool wall centered in the middle. Their instructions make no mention of using pavers at all if you put a crushed aggregate ring where the wall will be.
Again, any and all input is appreciated.
