Slab concrete crack fix, anyone tried it?

[Slednut]

I looked on Amazon, the reviews are mixed, some say it works great some had a problem with it not setting up. One guy said it was still tacky after 10 days.

I have some cracks in my driveway after a dump truck made many trips over it when we were building our addition. I always figured there's really nothing that would keep the cracks from getting worse with time.

Driveway cracks are always there to stay, only cosmetic patches are available. These must retain an amount of flexibility in order to compensate for changes in the environment. There has never been anything I am aware of that makes the crack as strong as it was originally, w/o tearing out the entire driveway and putting in a new proper one.

I used this on my parents driveway years ago. It worked great. It stays flexible so it will move with the concrete. It doesn't match very well on theirs but it is better than the crack.
