Hi all new to the forum and relatively new to a long term pool. Currently have a intex easy set with a 1000 gph filter n pump, 2.2 kw heater. All seems to be running good. The kids are loving it. My questions are as follows. Our back garden is small and have a decking and patio, then grass. The easy set is in my opinion its too small. The biggest i would want is 4m x 2.5m and im thinking about making my own pool to fit perfectly on out brick paved patio, i was planning to use euro pallets and 100 x 100 structural timbers completely around the pallets 3 rows of them one at bottom, mid and top. M12 coach bolted together. Will this be strong enough to support. The weight of the water approx 9500 litres as id like to avoid angled braces sticking out if possible?
