naw, this is an old thread but that guys floor there is not the foundation. I was searching for this answer myself and landed here. just to clarify ...my floor in our kitchen and is not on the ground floor there is a bedroom directly beneath it. SO NO FOUNDATION! I pulled up our tile and found this exact thing to a tee. seemed/looked more like they poured concrete over the foam part of carpeting which petrified the foam, then they tiled it. I am curious as to what he hell it is? i've been around for some time and been on multiple types of jobs and ive never seen anything like it. why it is so thick is beyond moronic. anyways yeah guess the only alternative is to get leveler or a bag of cement and fill the holes, after it sets use a grinder to help smooth where needed Im guessing. because taking it all out down to the wood would mean having to take out all of the existing tile too ( there may be cement board at the very bottom screwed to the floor itself but I dont want to find out.) I hope that anyone that comes across this doesnt listen to those other bits of "knowledge" its some sort of concrete type adhesive thats super thick - not a foundation, although it may have been directly applied on top of a foundation slab.
