I have a concrete square in my front driveway. How can a bring it out of the ground without breaking?

It has come loose and every time i drive over it rattles. I want to bring it up somehow and put more concrete underneath so that it becomes settled in the ground. It is an uneven surface.

  1. Cost effectiveness, remove said piece and pour a brand new piece. Trying to lift said piece of concrete without damage, the equipment, rental, and the labor will be more than just pouring brand new piece.

  2. There are companies that offer mudjacking services to raise up sunken concrete using hydraulic pumps and drilling holes in the concrete slab in various areas…then injecting concrete or grout into the holes under pressure to jack up/raise the slab…the concrete or grout then cures to make the slab solid again.. Might be a better option than doing it yourself….check the local Yellow Pages or call some concrete contractors or concrete firms for references.

    If you really want to DIY, you might try lifting the slab with prybars or 10′ long sections of one 1/2 pipe, block the slab in place and then fill in underneath with sand, gravel and/or concrete or mortar as best you can …push the material in place with a pushbar made from two X 2 lumber and some smaller boards nailed to the ends…then lower the slab carefully and hold in position until the concrete sets. I’ve raised a number of concrete porches or walkway/drivewayslabs for repositioning and it’s pretty easy with a couple guys and some pipes, blocks and leverage. Just be careful not to get under the slab with hands or arms, etc..and block it in position.

    Mudjacking info….

  3. You can rent a bobcat. Just saw some guys removing old sidewalk the other day but they weren’t concerned about keeping it in 1 piece & the scoop apparently was big enough to get the sections in 1 at a time.

  4. I’m going to guess it’s a smaller square because your car moves it.

    I would suggest putting an eyelet in the middle and picking it up with an engine lift.

    Engine lift can be rented, or bought at Harbour Freight for $179, and you’ll need a hammer drill and bit, plus the eyelet, so your total diy cost is $300.

  5. I would guess this is the typical three feet x three feet square and 4 thick. A square yard of concrete weighs 150 pounds per inch, so you are talking 600 pounds or so. Why bother? Break it up, lay some sand, and pour a brand new one.
