I mean, no waterproofing is going to be just as bad as laying concrete on top of.... *checks notes.....concrete board that's on top of foam and sand.

Part of me wants to post this to r/tile.... they'd have a field day.

I dont think you know how this works. As i said earlier, you cant rubberize a somewhat damp basement with concrete walls. Concrete needs to breath, especially in basements. And to be real, why do you see a need for a waterproof system in a basement with concrete everywhere? Really no point.

The ground is solid. Thats always a first step, even if you build a parking garage. The 2 layer foams, with boards on top, which are pretty sturdy if youve never worked with one, is kinda tough. And 12mm slab ontop which also filled gaps and what not. Dont be that guy, it holds up my bathtub with no problem, and my daughter jumps and plays without a crack.
