   several methods of jacking and cribbing, i have heard of some using wall jacks or pump jacks with the right rigging.

   your big problem i think is getting the sinking pile solid. who built it? when? see if any liabilities are expired, you maybe can get the pile crew to rejet?

   then after getting pile solid is the problem of re-attaching pile to structure and meeting code requirements, ya can't just throw a few blocks in there and call it good, it needs to be secured and spliced in a way that won't weaken structure to pile original connection.

   where are you at?

   I HAVE JUST STARTED THE PROJECT. THE HOUSE IS 25 YEARS OLD. I HAVE
   OWNED THE PLACE FOR 3 YEARS, AND HAVE NOTICED NO FURTHER SINKING.
   THE PILING IS IN GOOD SHAPE.
   I CAN GET COMPLETE ACCESS TO THE AREA. THINK I WILL START SLOWLY
   JACKING IT UP. I AGREE WITH YOU, THE KEY IS A PROPPER ATTACHMENT. I AM
   IN A HURRICANE AREA. ANY ADVICE?

   ya don't have to yell at me, my advice is to jack it up slowly. don't want to break anything getting it back to where it started. it came down slow and it should go back up slow.

   you will need to devise a system with which you can apply upward pressure, hold, and then increase and hold again.

   as far as reconnecting i would want lots more info, (detailed description of current condition with numbers) then i would propose my ideas to an engineer or the local building department to see what will be acceptable.

   again i would want to make sure the pile was done settling before i made a permanent fix. you saying it looks like it has stopped doesn't give me much reassurance in that area.

   is this an interior pile or is it on the perimeter?

   i would rig up a temp support so i could jack it back up to good slowly, and make sure to batten down the hatches before end of july, are you gulf coast or southeast? i am in southeast myself and i predict we wont get hit till 2008! you heard it here first folks!

   Didn't someone once say something about building your house on sand??

   I am no expert on this, but if the house has been there for a long while it must be somewhat settled.......

   I'd get a couple house jacks and lift the thing back into place......then I'd dig down to the bottom of the post (sand right?) where the bottom of the post has lifted I'd spread the weight out as much as possible......4' by 4' concrete pad/railroad ties/ etc.

   The house is floating on sand, so you got to spread the load on that post........shimming always screams ....f---up. do it underground....er under sand.

   excellent point, i didn't think of that.

   i have seen pressure grouting done to underpin/shore other foundation types, why not piles.

   i'd be willing to bet that its surrounded by a slab, we still didn't get answers to the question about whether its an interior or exterior pile, and the more better information supplied in the asking, the more better the answering.  

   there are a lot of things that come to mind, but i require some interest from the person asking the questions (you need to participate) or i feel like i'm talking to myself. copying and pasting the same answer to two different people in the same thread, cmon! we arent going to do all your thinking for you without at least a few strokes!

   I'm extremely interested in this topic and hope you are still active on this forum. You seem to be knowledgeable and I need some advice.
   I have one piling in particular I would like to repair and level if possible. Unfortunately, it is an interior piling. So, I am located on the gulf and the ground is basically clay around the house so I assume the same for under the concrete slab surrounding the pilings under the house.
   My goal is to:
   1- stabilize/secure the house around the piling to be repaired with 5-10t jacks
   2- break up the concrete around piling (as wide as necessary :/ )
   3- dig as far down as we can through the clay (hopefully it isn't all clay)
   4- expose the damaged area per the Simpson strong tie specs and jacket the piling and complete the necessary steps there
   5- ***need help here*** if I can jet around the piling (if that is even a good idea), while jetting put some pressure on the jacks (small amounts at a time of course) like a 1/4 of an inch per day I think? Let it, and the house settle in between days. Essentially, I'm trying to raise the original piling back into the original position.

   My questions are:
   - will this work?
   - what do you recommend if it isn't jettable?
   - how should I stabilize the piling while ground is dug up to avoid it returning back to the same spot? I'm sure we won't be able to dig down deep enough to get under the piling. Our downstairs where the pilings are is enclosed.

   Had the same problem on my beach house - the front porch. 2 inches. I jacked up the structure - bottle jack on a 3' piece of 4x8. And then my front door didn't close! I ended up getting within 1/2 of level, cutting it some shims in my door and balancing out the chaos. I Formed up concrete to get the pier to the new height, and I added a second new pier two feet from it.
