Hi All! Newbie here! I am looking to level a concrete slab that has settled in my 42 year old home. I have already contracted a foam-jacking company which has filled the entire underlying void with high-density poly foam to stabilize and prevent any further settling. The slab currently has a 1 1/2 - 2" variance at its lowest point. The room is approx. 550 sq ft. I am trying to achieve a level to where I can lay wood-look tiling to finish the floor. Self-leveler seems like a viable option, but would need to be poured in abundance to fill those deeper variances. Is there anything I can do to make up most of that space and then finish with a top coat of self-leveler? I also understand that many self-levelers can be extended with an aggregate. Any recommendations on a method to achieve this? Most say can be extended up to 4-5" with aggregate. That would be overkill. The neighboring bathroom and laundry room also have a minor slope to the floor that is 1/4-1/2" at most. Self-leveler should be able to remedy this issue. I would like the floors to tie-in/flow nicely from one room to the next. Thanks in advance!

Contact a company that does "mud jacking". They might be able to lift the lower sections.
If you simply use a self leveling product on the top, your ceilings will be different measurements from the finished floor and it will not be level to the world.
