Needs some "underliner ideas"

[bparks]

My wife had the great idea to use 2'x2' interlocking closed cell foam flooring squares. They often sell them in packs of 10, with different bright colors for kids play area flooring. the ones we found were all black, I think they were 1" thick. Got the at Sams club. They are closed cell, so they don't absorb water, and stiff enough that the weight of the water doesn't collapse them. Had them under our sofpool for three years, and other than the dirt they were about like new when we sold it. Wasn't the cheapest route to go, I think it was a little under $200 for our 18' round pool. Really felt great under foot though, and very durable.

Edit: this picture shows what I'm talking about, probably exaggerated the thickness above
