How do we level different floor heights on cement slab?

We removed walls to combine several rooms. Found one room has 1/2 inch more concrete than all the rest. Plus ceramic tile in 2 areas is same height as the high room. Jackhammer the 8X10' area? Or leave tile and pour over all the area fresh concrete to level the whole area? This level wouldn't match the rest of the house. Help! I just want a matching floor without tripping hazards.

    Have you checked into applying self-leveling concrete. Perhaps you could pour that into the low level area?

    I have a whole house of unleveled concrete floors. They are wavy and bow to the outside edges creating a mound. I have floated tile in a small area but the whole house? The tile guy at Lowes told me to use a liquid leveler. You pour it on and spread. When it is completely dry, down goes the tile. Again, You Tube shows how to do this. WikiHow is another resource I use.

    I read an article about a woman's first experience with this liquid leveler. She failed to consider and no one explained that the leveler is a LUQUID. If there are rooms below be sure to seal all cracks with concrete patch and let it dry before pouring the leveler. If one doesn't do this, the leveler will drip through to the ceiling in the room be low. Then you have to redo your ceilings.

    For me, I anticipate my flooring project to take a couple weeks to a month. I have 3 large rooms to do. They are very unlevel. I have never done this before and I am working alone. I work slower these days but I get it done.

    Use floor leveling compound.
