I have several flights of steps that are concrete. These are just 2 or 3 steps from the ground level to doors of the house. Solid concrete I think, some with mexican style tiles on top. The steps are not connected to the house but unfortunately some are connected to outside concrete pads further outside. Over the last 30 years or so, all those steps have started to sink a bit into the ground. Most by 4 to 6". So they are now slanted inwards towards the house. Some have cracked or cracked the attached pad. Depth towards the house is something like 4 to 5'. Width (parallel to wall) ranges from 6 to 20'. Height above the ground 2 to 3'. I imagine we are talking many thousands of lbs each.
So I will need to lift those back up and keep them there. This does not seem trivial. Of course I'm contemplating Portapower type devices to lift things but I likely should also think about the underlayment and reinforce/rebuild that so it does not sink again later on. That would not be easy for the big ones.
So, any suggestion on what techniques to research here? I remember seeing some vids of people lifting driveway bits with foam. Is that a realistic option?
