Options to raise concrete driveway
I have a concrete driveway that needs to be raised from zero to about 4 inches. The current concrete is in good condition. Just have water issue on it where need to park. I think where it needs to raise by 4 inches can pour additional concrete on top of it with rods drilled into current to prevent it moving. Now the from zero to about 3 inches thick must remove that concrete. Unless there is a material I am not aware of that could be used to build it up. Do not want to use asphalt.
Suggestions?

Options to raise concrete driveway
Oldguy, thank you.
Mudjackers? Is that the people who jack up a slab that has settled or such? I have seen add for a company here who does using some sort of fluid that hardens pumps up such slabs. kt

Options to raise concrete driveway
oldguy thank you very much. I do like your drawing and can understand it very well.
I spent a good bit of time tracking down and talking with a company who jacks up slabs and he did not suggest I do it on what I needed raised. He had at least two concerns and I will give your method a try if redoing a drain does not solve it which will cost less and not look odd as the raised slab would. He uses an expanding foam at about 1600 PSI that they inject through holes in the slab also but the foam does the lifting not as much by the 1600 PSI as the foam expands as it dries and that does the lifting. He said the problem for him is as much as I want to raise it, get it on right slope for the size of the slab with be tricky as when he injects the foam and it fully expands he is not able to add more if it needs to be lifted higher and for the size of the slab he thinks it would crack when he begins to jack it asking one corner to support the full size of that lift till more is supported.
You know as I typed that I now wonder how correct he was, makes me think he did not want the job. Maybe bigger than he likes to do for think sidewalks was he big preference.
