removing 4x4 post from concrete slab
Posted on 2/18/20 at 8:33 pm
Posted on 2/18/20 at 8:33 pm
The previous owner of my house installed a small concrete patio on the side of the house. They sunk 3 4x4 posts into the ground at the corners of the concrete. To be clear, the posts are within the perimeter of the slab - not on the outside of the perimeter. One of the posts is warped and I'd like to figure out a way to get it out of there without completely messing up the slab.
The only thing I've really come up with is to saw all the posts off at the base, try to saw them a bit deeper, then put a small fill of concrete on top. I'd then replace all three posts on the outside of the slab.
Any ideas? TIA.

Cut it off and drill/chisel the post out

Cut posts level with slab....or as close as you can get. Drill hole wide enough for a sawzall blade. Put long sawzall blade into hole and cut towards edge of post. Repeat in different directions. Question is how deep is post? Probably 12 to 15" so you need a drill bit that long and a sawzall blade that long.

Id probably just cut it off at the slab and put a steel pole bolted to the concrete in its place. Pictures of the existing condition are invaluable when these questions come up.
For future posters, put pictures in your posts if you want an accurate guestimation otherwise just pay a contractor to do the work.

I would cut them flush and use a 4"x4" post base or pedestal for the new posts

If you have what is called a farm jack (see below) or have a friend who drives a lifted jeep, you can likely pull it out. I've done it with wooden fence posts in concrete.

I got one out one time with a sledge hammer (to hit wooden post to break seal where concrete was attached to wood) and a farm jack like this from tractor supply.

I drilled a hole in the post and attached a block of wood to it with a 1/2" bolt and jacked it right up out of the slab.
Was not difficult.
