I hope I am putting this in the correct forum.
I just wanted to see if anyone else on here has had experience with leveling a tilting concrete slab? I have a 10' x 10' slab at the bottom of the deck stairs. I dug under it in a couple places and put jacks under it. I raised it up so that it was level if not a tiny bit more than it needs to be. My thinking is to add some slurry under it and then when I finally set it back down that it should be slightly tilted away from the house so water will run off away from the house. I have it cribbed up with blocks at this time. I have drilled four pilot holes thru it in locations that I think will be best for adding slurry. I will rent a core drill next week and punch thru some 2" holes where I have already drilled pilot holes. That's where I am at now with with project but I wanted to see if the way I am going about it sounds right to you all. I am planning to feed the slurry of sand and gravel and cement down thru the holes and pack it in there with a ram. I am also planning to shovel some under the edge where I have excavated and then using some sort of ram, pack it under from that position. I'm sure hoping this will work because in order to get a pumping rig in here to do it, it will cost 1-1/2 times what I paid for my table saw. : ( I just can't afford to spend $1000 to level a slab. If I have to, I will use some foam under it. Not that I want to.
