Floor leveler. $40 for a 40 pound bag. Not saying it’s the answer but should we feel sad for those that can afford that? Young women felt very sad when Princess Di died. Mother Teresa died around the same time. Different reaction(none). What happens when the next tragedy hits the Kennedy family? Gotta admit our Leaning Tower of Pisa is raising eyebrows. Only the classless would laugh-heh heh.
Nobody will notice that the wall is 3” shorter on that side of the room.
Floor leveller is not going to help with the increasing tilt of the entire building. In fact, it will make the problem worse by adding weight to the side that is sinking.
The developer and all involved (especially the building inspectors and foundation engineers) with the construction should be held personally responsible and the building needs to come down before it collapses.
