Hi everyone. We have an Ultra Intex 16' and spent a week leveling our sloped ground. Finally got it!!! Put our extruded polystyrene down then a tarp and hubby has put the pavers on top of that....now I am thinking they should be buried flush? Is it ok to have the pavers on the insulation...pavers are about 2" high or do we need to bury them level? Thanks!!!!
