How much for the break-up and removal of the old slab? I believe that my neighbors paid in the $1500 range for their redo of the same size pad. I have too many fun project lined up(building master Bdrm closet shelves and drawers) to allot time for this. At the price I received I'm going to give the injection a try. The price is reasonable and for the time it would take me to attempt this myself I'd rather free up that time.

Burying 'construction debris' is a big no no on any job site. I'd get it out of there and start fresh. The rebar idea is good advise IMO

4x10 is almost 3x as many 80# bags as 7x2 (23 vs 8).

I would've just paid the $225 for 1 cu ft of delivered concrete at that point and used a wheel barrow to dump it in.

($125 for 1 cu ft + $100 delivery fee is typical for anything under 5 cu ft) these days.

When I added my patio is it took about 30-40 mins to get the concrete on the ground and that was a 10x12.

How much was the injection? $1500 sounds extreme, I would never pay that, I can't believe these places get that much for concrete work. Blows my mind. The quote to add on my patio was $1800 I did it for under $300 including everything (2x6's, trowels, etc.).

The mudjacking works very well, and lasts. And the company you're in contact with is one of the most honest I have ever worked with. Excellent all the way around.

I agree with bjohnsonb. Concrete Raising of NC did a great job on my concrete driveway. Very professional and highly recommended.

For those you think you're going to be better off ripping out concrete and pouring a down a new slab, think again. In many cases, a builder does not compact the soil around a house well enough before pouring concrete for the driveway or sidewalks. The soil will continue to sink and you'll probably have to do the same thing again -- but the key is that it's much less expensive to do another concrete jacking rather than pouring a whole new slab of concrete.

I will add that it's been a couple of years since I had my driveway mud jacked and it still looks great. So depending on your situation, you might only need to have mud jacking treatment once.
