ilililhy1 does it work? Perhaps.does it look like a professional did it ? No.

Grab a hammer and break a few ceramic floor tiles in pieces big enough for shims...they will never deteorate...

Roofing shingles can emit toxic gases into your living spaces. If your use of them is sparse, then the danger would be negligible and relatively safe.

Jay Smith yeah shingle won't work they will let your joists sink into the shingle

I have considered your proposal and have concerns about ceramic tiles breaking under uneven pressure from heavy objects being placed in unfortunate areas after the fact.

dumbest comment ever. tile will break like glass and make noise just the same

Asphalt shingles

Self leveler would not work with a discrepancy of 2 inches. The drying process alone would take forever and be subject to shrinkage.

Jay Smith what if u add gravel to it. Allow drying for 24hr

In a house this old, the foundation would most likely be stacked stone. Current code would not allow this to be set back to level without replacing the basement wall with cinderblock or cement. The cost effectiveness is lost when this is factored in. The solution in this video is viable and permanent as long as the material used is placed over the original floor joists, and glued and screwed. The only problem with lost space will occur with the inconsistency of the height of the walls. A "settled" foundation is far sturdier, than one that has been replaced, and yet to "settle", with everything being equal.

fixing the foundation would be more costly and wouldn't promise you anything in the long run. The best fix is always to start new but its not always the cheapest or easiest.

You don't do it in every room, only where it's about an inch or worse difference between the highest and lowest points, that's the most cost effective and easy way to fix that gap. Many contractors do it and the home owners are not even aware of it.
