Leveling Floor Help - End of rooms are off by over 1 inch (**pictures**)

Hello,

I'm new to this forum and I would appreciate any help I can get. I'm closing on a fixer-upper house next Wednesday and I need your help. I had a house inspection already, and the foundation seems fine. But, the slab in the back two rooms are not level. The inspector (he's done over 6,000 inspections so I trust what he says, also was a referral from my Realtor) believes the slab was actually poured 1 inch too low in the back two rooms when the house was built in 1982. There are no cracks in the windowsill, or on the exterior or interior walls. Just one very thin hairline crack in the middle of the room.

The back two rooms are actually level in half of the room. About in the middle is where the back half of the room starts dipping, and at the end wall it dips to just over 1 inch.

I'm really tight on my budget right now and I don't think I can actually lay laminate down because of the 1 inch gap. The gap starts out small halfway in the middle of each 10x12 room. It slopes 1 inch in just 6 feet.

What I'm thinking about doing is using some self-leveling concrete underlayment. Such as the one at Home Depot here:

Custom Building Products LevelQuik RS 50 lb. Rapid-Setting Self-Leveling Underlayment - LQ50 at The Home Depot

I've heard great reviews about this. Will this product work in my case? If so, how many bags do you think it will take? Any suggestions/help I can get on how to use this product would be greatly appreciated. Or, do you have any other ideas for a quick cheap leveling fix on my two bedrooms?



(You can see the baseboards are straight across, but are up 1 inch from the floor in this picture).



Thank you so much! Any response is appreciated.

-James

Does the dropoff start where the crack is? Is the surface the same height on each side of the crack, or is one side lower.

If you have never used self leveler before, do not attempt to use rapid set. Use the Level Quik ES, as it'll give you a lot more open time to work with. Do your homework on slc. You'll need a helper, as you need to work fast, and have everything ready to go. You have to dam off any openings, as this stuff will run like water and find every crack, crevice and hole to run into. Don't forget to use the recommended primer on the slab before pouring. Follow the instructions to a T. Do not try to make the mix thicker or thinner than recommend.

You'll have to carefully measure the area to determine how may bags you'll need. Buy more than you need, as you do not want to run short while you are pouring. Return the extra bags if you have any. You mentioned a budget issue. Know that this stuff is expensive as all hell, and youll likely need a lot.

Do an internet search, as there are some good articles out there to read on slc.
