This concrete slab is not thicker than 1 to 1.5in thick. This is the same thing that I drilled in the living room for the fireplace steel framing. Jumping on the floor in the middle of the living room, the floor does bounce (but again I am 200# ..). I dont believe it is structural, but rather insulating against noise, fire, moisture and most of all to offer a flat and somehow rigid surface for flooring.. Nowhere in the house does it feel like solid 4 to 6 in concrete floor with rebar..
Please re-assume me in regards to structural. I really dont want to mess with structurals!
Since the first tiles were removed within minutes, I have decided to remove all tiles and start fresh. The DW is easily removable (its a new DW that I installed myself in May 2012). There is about 1in left of space underneath so theoretically speaking I could raise the floor up to an inch before the DW no longer fits in the cabinets.
around next weekend, I will have removed all lower cupboards and pantry, all appliances, removed all tiles and then I will be ready to scrape as much of this thinset as I can.
To remove the leftover thinset, a grinder would do? This is gonna make an awful amount of dust!!! Better tape off every cabinet remaining and door openings or else I will have silicosis...
