Last year, I had a sidewalk that had sunk a bit. I do not remember the numbers, but it was similar to 1/8" on one side and say 3/4" on the other, perhaps a bit less. The city told me to fix it so I purchased Quikrete Concrete Resurfacer . It was not cheap (over $20 for 40 pounds), but I only needed 3 bags. Loved it.

There is a dip in my sidewalk, it has always been there. The problem is that water accumulates there and in the winter I get an ice patch. I want to raise the sidewalk, figured I would do the same thing. The dip is not because the side walk sunk, it is because that is how it was laid (I think). Been that way for the 16 years (or more) that I have been here.
Call it 10 foot long, 48" wide, and the center is down 2.5" I figure that I need roughly 15 bags (600 pounds). OK, perhaps it is between 12 and 15...
I started looking at my local home depot and lowes (have not looked at minards). They now carry Quikrete Re-Cap concrete Resurfacer for about $27 a bag.

I read in a review that this was more difficult to work with in that it is very finicky compared to the concrete resurfacer. I did not pursue that since it looked like Sakrete has a similar product (takes longer to cure) that would save me a bunch of money.
I keep seeing Sakrete Top'N Bond Concrete Patcher, which is listing at $17 for 40 pounds with about the same coverage. This would save $150 (plus tax)

Problem is that Lowes near me stopped carrying it. I might be able to drive 50 miles to get some (ouch).
I was looking at these specific products because if I break this out, then I need to figure out how to get rid of the concrete, and it will take a lot more concrete to break out the existing and then build it up so that it does not have that dip. I will have rather thin layers near each end....
Any suggestions?
Oh, while talking about concrete...
I need to cut out the main floor drain in my basement and replace it. OK, use a diamond blade and cut around it, then see how far in I need to go before I get something that I can connect to; will be no more than 3 feet unless the elbow in the cast pipe is broken then I would need to replace a section of that pipe. The main pipe is known to be at least mostly good because it looks just fine when we shoved a camera down the main line. No clean-out on the existing floor drain so no idea what that looks like from it to the main drain a few feet (less than 3) away.
Never done anything like this, but, what kind of concrete would I use to patch up that hole after I poured in my gravel around my new line?
