I have done a lot of reading here. Thanks for all the information provided here. Now I have a question. This is the second year that I have set up my intex 32*16 ultra frame pool. I used the same pavers as last year, which are 8 inches wide*16 long *1 1/2 high. Last year I had 1 or two blocks sink on the front end and tip so that the end of the support was at the front of the block, but I let it go and had no problems.
