Nothing but rain all week and progress is going slow. I was hoping to have the pool up this weekend but that's not going to happen. The rain will continue throughout the weekend. We had some heavy rain last night and this is what the dig site looked like this morning after about 2-3'' of water had been absorbed into the ground:

Maybe I should just turn this into an inground project . So how much bleach to clear up that water?

I think I'm pretty much level so my next step will be to lay out the foam. I read through a lot of builds and there are so many different ways to set up the base that have worked for people.

I think I've decided to go this way:
first layer - Landscape paper or tarp
second layer - 1" XPS foam
Then pool (maybe another tarp on foam)
Since this pool will only be used for 2 months max before coming down I was thinking I may be able to get away from using pavers. It seems just having the legs sit on the foam has worked for a lot of people especially where there is hard compacted ground in place, which I have (cement like clay). The only problem is, I don't know if I'll have enough foam outside of the pool's diameter to accommodate the legs. I know 8 4x8 sheets will be enough for the pool but does it give enough foam for the legs to move out a little? Any feedback from people that would know would be great.
