I have a concrete driveway that is 15 months old. About 4 months ago the surface began to loosen and finally just crumble away in various spots from the size of 1-2" up to 6 x6" and it appears that the entire surface is going to follow suit.

Any suggestions of what is causing this and the best approach to repair. So far, a law suit is all that will affect the builder.
