Your pool holds a bit over 14,000 gallons. A gallon of water weighs approx. 8 pounds, so that is 112,000 pounds or 56 tons of water you have there. Draining 4" is like spitting in the wind -- yes, it reduces the weight by a few tons, but there's still an awful lot left.Well not good we had a rain storm last night into early this morning now we have several busted pavers so I drained about 4" of water just to be on the safe side . I knew I shouldn't of went with compression sand ,so I guess it's going on a concrete slab now .
Yes but wood is much more forgiving and will bend instead of cracking.Pressure treated wood can be used. It's what's under the wood, pavers that creates problems. If the subase under the wood or pavers is not compacted it will settle, crack the pavers. ��
