    polyurethane mudjacking

    I have a void under my garage and a sinking slab under the deck. I have seen some companies doing polyurethane mudjacking. Does anyone have experience with this?
    Is it better than mortar?
    What's the price difference?

    I plan on getting some quotes next week.

    I had three sidewalk area mudjacked for $200 the whole fashioned mortar way. One slipped back to its old position. I say try the new stuff.

    Re: polyurethane mudjacking

    The poly works damn good. I've seen it used on commercial jobs under slab, and plumbers use it to fill voids under showers and tubs.


    That rug really tied the room together, did it not dude?

    Regardless of which you choose......mudjacking just buys you time. Eventually you will need to repair the base that is failing. If you can afford to do that now....I suggest that. If not....then mudjacking is the way to go until you can afford to fix the problem properly.

    That's not necessarily true. If water is causing the issue (like a poorly placed down spout), if you correct the water issue and then mud/sand/poly jack the slab, you likely could find the repair to be essentially permanent.

    This was the issue for my patio. I extended the down spout beyond the slab (which used to discharge directly into the patio and then run into the control joints) then into drain tile. I had the slab sand-jacked. It's been over 7 years and the slab hasn't moved a bit.

    Re: polyurethane mudjacking

    Mudjacking is just a bandaid that will fail over time. Honestly, you might need to get a geotechnical engineer involved to do some soils borings. You could have expansive soils. We have had quite a few projects where we've had to repair foundations that are sinking/moving because of expansive soils.
