How to insulate a concrete porch?
I have a big outdoor porch and part of it is above an enclosed swimming pool room. It is concrete porch and has porcelain tile on 2 inches of cement subfloor [mud].
When it rains and during winter [snow in Michigan], I have problems in the swimming pool room.
How can I insulate the concrete slab if i remove the existing tile? I want to take the tile out, insulate[foam or something], waterproof the area, and reinstall something, either porcelain or some kind of slate or blue stone.
Is there some kind of product or method to insulate the concrete slab and then mud over and waterproof and install tile over?
