Sinking Piling on Beach House

m1234's picture

FIRST TIME POSTER......NEED HELP PLEASE!!!!!!!!!

I need to level the sinking floor on my beach house. One of the pilings has sunk 4-6 inches, and is making all the front sliding doors difficult to operate. Has anyone tried to shim between the top of the piling and the floor joists? What is the preferred method to jack up the low spot?

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!
