I am installing an intex 12'X24'x52" rectangular pool. I am confused about what kind of base to put under the legs. Intex says to use 15"X15"x1.2" pressure treated wood, or steel pads or reinforced tiles. I can't seem to locate PT wood that is 15" wide, and I've read that the wood breaks under the weight.. I have no idea where to buy steel pads or reinforced tile. I've also read in various threads that 1 inch patio pavers break. Is there a consensus on the best thing to support legs on this type of pool? I read in a few thread that 16'x16'x4 is a good choice. But, I have to special order those (not carried locally.) Do 1.5 pavers work? Any tips on where to find steel pads or reinforced tiles? This pool has 18 legs to support. I previously had a 15' round intex on this spot, but we never used pavers. I want to get the pavers right the first time so we don't waste time/effort/water. Thanks for any insight you have!
