If anyone knows there way around concrete, I sure have a question:

I want to to some patching and touchup on my concrete driveway to try
and postpone the inevitable replacement.

Does new concrete adhere to the older concrete? One pad at the
entrance to the garage has drooped, and so I have about a 1.5 inch bump
to drive over. I just want to smooth that with cement from the Home
Depot, knowing that it will continue to drop a bit further, eventually
crack off, and require full replacement of the pad one day. Just hoping
to postpone the inevitable due to finance issues.

If I smooth that bump, will the concrete "stick" to the driveway, or
will I just be creating a sort of angled piece of concrete that will
slide off the existing surface?

Hope I explained that okay, as I don't know anything about concrete,
other than I know that fixing my driveway will one day cost me a
fortune :-)

Thanks,

Mark

It won't stick very well but short of replacing a larger section of the
driveway, its the only patch you can do. Buy some of the higher
strength concrete at Home Depot, etc. Get Rapid Set if they have it. It
sets up fast and has a higher PSI rating.
