Leveling concrete slab
I have a 2 bedroom one bath addition on a slab. The slab has cracked and is very uneven after so many northeast winters (40+ years). I would like to keep the addition but am having issues with doors and floors because of the slope. As well as the addition slowly pulling away from the main house up in the joists. What is the most cost effective way to level the addition safely?
Thanks for your input.

Mud jacking is probably going to be the best approach although maybe helical piles would also work. It all depends on the soil types in your area. To get the easiest and correct answer you should probably contact a civil/structural engineer in your area.

There are too many unknowns for anyone on this forum to provide meaningful solutions to your house's problems. If the slab concrete is junk, mudjacking will definitely not work. Also, I've never seen helical piers successfully used with conventional concrete slab construction, either, as most slabs aren't designed to maintain their integrity between stemwalls that are being lifted by exterior helical piers.

Your description of the slab's condition makes me think that wouldn't be very practical nor feasible. Totally different story if the slab was sound and adequately reinforced, with little or no cracking. Any chance you could include a few pix, to let us see what you're seeing?
