Concrete pad leveling

Options
Anyone here have a concrete pad re-leveled?

My garage pad has a cracked and sunken section that would like fixed. If you have had it done, how were the results and what did they charge?

One of my neighbors said he heard it was between $3-4K for it to be done, and if that’s the case I could probably just have it ripped out and replaced for nearly the same amount!

    Mud jacking for just a slab seems impractical unless it's a load bearing issue but I guess you you need to figure out why it subsided.

    My buddy used to own a concrete leveling business and I think he charged around $400-$500 per slab, but that was over ten years ago. He used lime to do it, but now some use spray foam. Not sure which one is better.

    Groundhog or chipmunk problem eh?

    My very limited experience is jacking the aqueduct and it was way more economical and faster than demo and replace.

    Find a company that uses polyurethane injection. They come in, drill holes, squirt in the juice. Not an eternal fix, but damn near. The technology has changed quite a bit in the last ten years.

    The ones I’ve seen around here are the ones where they drill holes and poly fill.

    The issue was an old water problem.

    We have done a lot of drainage work around our house...

    Replacing the pad does seem like overkill, but if I’m close to the same cost, why repair when you can just have new, right?

    Yes, that’s the ticket.

    It is overkill. Let me know how that goes. Have you priced concrete by the yard lately? Let alone labor costs since everyone’s so busy.
    It will be much cheaper to go the poly route, and hold up pretty well.

    I know for sidewalk work, our bill is $7sqft finished plus concrete.
    A yard of the grey stuff is roughly $120.

    It will really come down to how much the price difference is.

    This is also a 40 year old slab, so I’m also considering the fact that it’s not in the best shape to begin with. I’m going to make some calls this week.

    Makes a big difference if it’s not in good condition.

    Concrete doesn't deteriorate over time. It only gets stronger. Now freeze thaw and vibrational stress is it's enemy.

    Being in NY, we have plenty of freeze/thaw cycles.

    40 years of cars parking on it. Snow, ice and rain dripping on it and the massive amounts road salt over the winters.

    It’s a salvageable pad, but I’m only going to go through with a repair if the cost makes sense.

    If you do replace it have them add fiber to it. It will never crack.

    Never is a very definite word. Only saying because I’ve seen it. If you don’t want concrete to crack, use asphalt. ;)

    And that stuff (asphalt) often cracks up here in the Frozen White North (at any rate). Any of you who know the term frost heave have likely experienced it. ;)

    Extremely good bed prep can minimize it -- but it is pretty much inevitable.
    Concrete's pretty much anathema up here -- not utterly unused, but none too common.

    Dirt is still pretty popular for pavement road surfaces here -- and gravel for driveways and parking pads.

    I used to promise every excited new home owner two things before they went to the closing table- You’re concrete will get hard, and it will crack.

    Update:

    Got the quote to have it done, leveling the pad and sealing the crack back up will be $1,900.

    Definitely less than replacing the pad.

    This is the polyurethane leveling to fill the voids and bring the pad back together.

    Once it’s repaired and leveled, I might have the surface epoxied.
