Grinding NEVER fixes the problem.
All you do is just Kick the Can down the road because you haven't addressed the main issue, the problem under the piece that has sunk. It will just keep sinking and you grind again and again.

When you have a piece of concrete that has sunken down, how does grinding off the good piece fix the bad piece?
Think about it, Let's say you have a brick mailbox and a car knocks a brick out of one side. Do you knock a brick out of the other side so the sides match or do you fix it?
Year one you Grind.
Year two or three it goes down more and you grind again.
A Year or so later the problem returns because you haven't addressed the main issue. Now you can't grind anymore so you must replace the whole section. You end Paying Triple.
Companies that do grinding have Job Security. They know the problem will return in a year or two at the most. For that reason they DON'T warranty their work. They put you on a regular two year schedule and sell you again and again.
See some examples below.
Grinding NEVER solves the problem.
Grinding never solves the issue. Here it created a low spot that will surly pond up and cause an issue in the winter.
Same here, a ponding issue and the trip hazard isn't really gone.
Ponding as seen here.
Again the ponding issue.
Typically cannot grind a curb. What's not seen is the drain just over the curb line. Leaving this will eventually take out the sidewalk, curb and even the drain.
The sunken section will keep going down and the grind will happen again, and then again, and eventually the whole area will need to be replaced. It's to the point now that there is a pond in the winter.
The trip hazard isn't gone but we managed to stabilize it. Too bad we weren't called in earlier.
Couldn't raise it properly because of the grind. There will now always be a slight ponding issue at the bottom.
At least we were called in before this got worse. It dropped, they ground, it dropped again so they decided grinding wasn't going to work. We stopped the deterioration.
This section had been ground down TWICE. Note the problem, grinding down the piece next to the one that has dropped NEVER solves the problem.
The root of the problem needs to be solved with ROADBASE. Mud, Sand or Foam will not do the trick as those ALWAYS sink again.

Another example of grinding not solving the problem. The settling is caused by the lateral line from the hydrant going under the concrete. Until the root of the problem is fixed all the grinding in the world will not solve the problem, it will jsut keep going down.
Just do their THIRD grind. We see this a lot. They are starting to run out of good concrete to grind.
See now why the grinding guys have job security?
