So we are having our entire 2 month old concrete deck tore out and going with concrete pavers. For those in the know how important is the geotextile membrane? From what I can find it needs to be on the top of the native soil. Reason I ask is we will need to remove 4.5-5" of base gravel and the entire drainage system to do this. If it's a must I will. If I recall the original excavation was 8-9" below the top of the coping. So I should have adequate base @ 4-5", I figure I may need to add another inch of base. If I need more I could go with the thinner pavers.
So drainage system. Currently I gave about 20 round spot drains astound the pool, looking at photos of pool decks it appears my guys put way too many drains in. Are there any challenges with round spot drains? Would I be better off with something like the deco drains, on the perimeter?
